The Recent Formulas section shows the last formulas you modified. Tapping one of these will automatically take you to where you left off.

The Macerating Perfumes section shows the latest fragrances you created and how many days are left before they’re ready to use.

The calculator shortcut takes you straight to the Estimations Calculator inside The Lab.

The Upcoming Alarms section serves as a visual reminder. This is most useful when your notifications are turned off.

First, you'll notice a handle to the left of the screen. Tapping it opens the Formulas Drawer. All unfinished formulas are here. When you want to work on a formula, select it from this drawer or tap the + button to start a new one. Once a formula is selected, The Lab reorganizes itself.

A second handle appears to the right of the screen once a formula is selected. This is the Oils Drawer. You can add oils from your supplies to this drawer for quick access, then *remove them when you no longer need them. To remove an oil, simply press and hold the targeted item.

(*Removing oils from here does not delete them from your supplies.)

To add drops to the mix, tap an oil from this drawer and select the number of drops you wish to add from the wheel. In order to avoid losing count, you are limited to adding no more than 10 drops at a time. After each addition, the lab updates itself and plays an animation, reminding you to swirl the bottle and blend in the new ingredient.

The droplet above the amber bottle shows the total number of drops in the mix, while the white label shows its equivalent in milliliters. Tapping this droplet also opens the oils drawer.

The list at the top left is the Formula Steps. Each time you make an addition to the mix, the timestamp and oil details are registered as a new entry. Tapping an entry tells you the number of days that particular addition was allowed to *mature for.

(*When two oils sit together, they meld more and more over time.)

The list at the top right is the Ingredients List. Each time you modify the mix, the list updates accordingly. Tapping an entry tells you that ingredient’s percentage within the mix.

Hint: If a list is too small to read, place your finger on top of it without triggering the scroll, hold it for one second, then slide it up/down to enable Magnifying Glass Mode.

The box under the ingredients shows the Top, Middle, Base ratio. Tapping these will tell you that type’s percentage within the mix.

The box under the steps shows the three key estimations of the final product. The NCA and EFV values update as your formula progresses, while the DC can be modified at any time through the *clipboard. (*See the clipboard tutorial.)

Desired Concentration:
the targeted concentration.

Necessary Carrier Amount:
the carrier volume needed to reach the desired concentration when finishing the formula.

Estimated Final Volume:
the volume of your final product once you mix the amber bottle’s contents with the necessary carrier amount.

Hint: If you forget what the initials stand for, press and hold to display the full name.

The Lab consists of 3 stations:

Timer (left)
Mixing (center)
Calculator (right).

To *switch between stations, swipe the screen. ← →

(*To temporarily prevent switching, tap the purple lock icon.)

The Timer Station allows you to set alarms, which can be useful when you want a formula to mature for a specific number of days before proceeding further.

To set an alarm, simply tap the timer, enter the number of days (left) and hours (right), then tap the Start Button above it. You will notice the button changes from "Start" to "Stop", indicating that the timer is running. If a timer shows "00:00" but the button still says "Stop", it means there are less than 60 minutes remaining. You can stop a timer at any time by tapping the Stop Button. Otherwise, you will receive a notification when the time is up (as long as the Allow Alarms setting is enabled). Since timing in perfumery is crucial, the notification cannot be dismissed until it has been opened.

Above the timer is a Sticky Board. You can temporarily attach journal pages to this frame to use as guidance or inspiration at quick glance. While a page is on the board, tapping the top right button takes it down while the top left button takes you to the journal.

(Since the timer and sticky board cannot be used while no formula is selected, attempting to do so will redirect you to the Mixing Station.)

The Calculator Station is where the math is done for you. Sometimes you need to know a fragrance’s exact “measurements” in advance. This calculator was designed to compute three variables dependent on each other:

Final Drops: total number of fragrant oil drops

Final Volume: oil drops + carrier amount

Concentration: carrier/oil ratio***

Checking the radio button to the left of a variable will lock its current value in place. Modifying one of the two remaining values will automatically adjust the last one. Here are a few examples of how the mechanism works:

Find out how many fragrant drops you need for a 100ml bottle of perfume with a concentration of 20%:

1. set the Final Volume to 100, then lock it. The volume will now remain unchanged.

2. Set the Concentration to 20. The value of the Final Drops will update automatically.

3. Your answer is 400 drops.

Find out how many milliliters of perfume you will end up with if your current drops are at 43 and your desired concentration is 15%:

1. Set the Final Drops to 43, then lock it.

2. Set the Concentration to 15.

3. Your answer is 14.33 mL of perfume.

Find out what concentration will you reach if your have 120 fragrant drops and hope to fit your perfume in a 20mL bottle:

1. Set the Final Volume to 20, then lock it.

2. Set the Final Drops to 120.

3. Your answer is 30%.

The Clipboard becomes visible at the bottom when a formula is selected. It contains your formula’s name, starting date, concentration, collection, and description. You can modify most of the clipboard's contents at any time.

The starting date is set the moment you add the very first drop to a new formula. You cannot modify it. Tapping it will tell you the total number of days your mix has matured for as a whole.

While the description field’s intended purpose is to describe the formula’s final scent, you can opt to use it for taking notes or logging your progress instead. Keep in mind that its contents will be saved to the final recipe once the formula is completed.

When selecting a concentration, remember you have the option to create either a perfume or a blend. A blend is a mix of fragrant oils at 100% concentration; no carrier. Finishing a formula as a blend will add a new object to the supplies in the Oils section, while finishing it as a perfume will add a new object to the Perfumes section instead.
Modifying the clipboard concentration also modifies the DC, NCA, and EFV values. (*See the DC, NCA, EFV tutorial.)

When you start a new formula, you may notice your concentration adjust by itself when you attempt to set it to your desired value. This is normal. It happens when the app computes a necessary carrier amount below 1 drop, which is physically impossible. As your formula progresses and your drop count increases, so does your concentration threshold.

The button at the top left of the clipboard is the Brainstorm Button. Tapping it will save the current recipe as a brainstorm entry inside the journal. This feature can be used to create save points as the formula progresses.

The button at the top right of the clipboard is the Finish Button. Tapping it will prompt you to select a fitting bottle, a carrier (if applicable), and a cover picture for your finalized product. You also have the option to set a price tag. Once the formula is completed, its recipe page is added to the Journal.

Formula pages are read-only, which means you cannot modify nor permanently delete a completed formula. You can, however, *archive a formula by long-pressing it. (*See archives section.) New pages can only be added to this section by completing a formula in The Lab ~ Create.

These pages can be used to recreate the scent and mix new batches by pressing the Remix Button at the bottom right.

You can choose to *remix the original quantity or increase it by a multiplier. This allows you to either create multiple products at once, or one single product in a larger dose. (See remix section.)

Brainstorms work like ordinary notes. Whenever inspiration hits you, note things down on a new brainstorm page inside the journal. You can then attach it to The Lab's sticky board to use as reference for a new formula later on. You can delete a brainstorm by long-pressing it.

The journal comes with an optional lock, which can be set by *enabling the option in the Settings.

(*Once enabled, access to both the Journal and The Lab will be protected by a password. See the lock tutorial.)

The Remix Drawer to the left contains the unfinished remixes. When you want to work on a remix, select it from this drawer or tap the + button to start a new one. Once a remix is selected, The Lab reorganizes itself.

The list at the top shows you the steps to follow in order to successfully replicate the scent. Each entry has two sub-steps: the added drops and the waiting time. Perfumery is all about timing. Simply adding the same ingredients but neglecting the time intervals will not guarantee the exact same final scent. For this reason, it is recommended to keep *alarms enabled in Settings so the app can send out the necessary reminders. (*See the alarms tutorial.)

Once you add the indicated drops and check the box for that step, the Timer starts automatically. You will notice the list of steps does not allow you to proceed further until the waiting time is up. If you fail to add the next drops in time, the list still allows you to continue, but each delay affects how closely the final scent matches the original. Following the list's strict steps allows you to replicate the scent to a T.

The Finish Button at the bottom right is disabled until the progress bar is complete. The progress bar advances with each checked step.

Tapping the enabled finish button will prompt you to select a bottle, carrier (if applicable), and cover picture. If a multiplier was selected, you have the option to use either one or multiple bottles, as long as the capacity and quantity available allow it. You can also reuse the original cover picture and price by checking the option boxes.

These shelves can hold both perfumes created by you and commercial ones you may own. You can use this section to keep track of your perfumes’ notes, their scent profiles, or to mark your favorites.

Scent profiles show up as hashtags. You can use this feature to put different labels on your perfumes such as #fresh, #floral, #sweet, etc. To add a scent profile, type a maximum of 13 characters next to the +. Once you tap the + button, the label appears next to a - bellow. Tapping the - removes the scent profile. You will notice each entry comes with a light/moderate/heavy selection. You can use these to organize the hashtags by intensity.

When it comes to your own creations, you can also track the maceration time. The Timer Icon at the top right corner shows the amount of days you must wait until the maceration process is complete and the product is ready for use.

Once you open the drawer of a self-made perfume, you can tap the bottom-right button to go straight to that perfume's formula recipe within the Journal section.

When adding a commercial perfume, you have the option to list the notes contained in the fragrance. You can either distribute each note to its respective T/M/B category, or skip the hassle by selecting Uncategorized from the drop-down.

To add a note, type its name next to the +. Entering the first three letters opens a list of notes currently recognized by the app. If the note you wish to add is not shown, you must add it manually by going to the Library section. Once you select a note from the list, it appears next to a - bellow. Tapping the - removes the note.

Once you open the drawer of a commercial perfume, you can tap the bottom-right button to save that perfume's list of notes as a brainstorm page inside the journal. This can be useful when creating dupes of commercial fragrances. Simply tap the Brainstorm Button of the fragrance you wish to replicate, then go to The Lab and attach that page to the sticky board, so you can follow it as you work on the formula.

All perfume names and brands are used for identification purposes only. This app is not affiliated with, endorsed by, or associated with any of these brands.

These Guides are meant to ease you into the world of perfumery. Things may seem confusing at first, but once you get a grasp on the T/M/B ordeal, everything else falls into place. You might still confuse maturation with maceration, but it's nothing a quick glance back at the guides won't fix.

This app comes pre-equipped with over 400 perfumery Notes. These notes are used when adding new oils to your supplies and new commercial perfumes to your shelves. As the art of perfumery expands and new notes come to light, you are able to add new ones at any time. Notes you add yourself are considered custom notes and can be identified by the asterisk symbol. Custom notes can be edited at any time. Default notes on the other hand, cannot.

Oils are categorized as notes and blends. Notes represent one specific ingredient, such as vanilla, lavender, or jasmine. Blends are a mix of a multitude of notes typically meant to evoke an ambiance or an impression, such as tropical forest, fresh linen, or baby powder.

Every single drop is monitored. Every time you add drops to a formula or a remix, the amount is deducted from the supplies. If an oil runs low, the number of drops turns red.

When adding a new oil as a note, typing the first three letters of the name will open a drop-down list of notes currently recognized by the app. Tap the note that matches what you're searching for from that list to select it. If you cannot find it in the list, either add the oil as a blend instead, or go to the Library section and register the note yourself.

When adding or editing an oil, you can set the volume to either drops, ounces, pounds, or milliliters. Once you confirm the changes, however, the volume is converted and displayed as drops and milliliters by default. Avoid switching between units other than drops and milliliters when editing used oils, since the exact number of drops will be lost in the conversion.

A carrier can either be an oil or an alcohol, creating oil-based and alcohol-based perfumes respectively.

The volume of carriers is tracked the same way drops are for fragrant oils. Every time you use a carrier to finish a formula, the amount gets deducted from the supplies. When the volume gets critically low, the number turns red.

When adding or editing a carrier, the volume can be set to either drops, ounces, pounds, or milliliters. Once you confirm the changes, however, the volume is automatically converted to milliliters, as this is the default unit in perfumery. Avoid switching between units repeatedly when editing used carriers, since the exact amount of milliliters will be lost in the conversion.

There are three types of bottles used in perfumery:

Atomizers: allow you to spray alcohol-based perfume. The most common and modern option.

Roll-ons: allow you to smear oil-based perfume directly onto skin. This is how perfume was traditionally applied.

Stoppers: prevent air from entering the bottle. There are different types of stopper bottles. Some come with built-in pipettes, some with glass sticks, some with intricate openings allowing the oil to drip out without spilling. Whenever you buy fragrance oils, they come in stopper bottles.

We have created a pre-made list of quality yet affordable boutiques that we personally tested and handpicked for you. Nonetheless, you can always remove ours and add your own favorite brands instead.

Since different vendors have different products available for sale, check the appropriate boxes when adding new links. You can then use the tabs at the top to filter through and shop for specific items.

Boutique links lead to third-party websites. Scentsaga is not affiliated with these vendors and does not process or handle any payments for purchases made on external sites.

The app’s most important feature next to The Lab itself is its alarm system. Receiving reminders when timers run out is crucial for the precision of perfume making. Nonetheless, you can opt out of this feature by disabling the Allow Alarms option. This will not, however, prevent the timers from working. Likewise, the home page will continue displaying any upcoming alarms.

Enabling this lock will prompt you to select a 4-digit pin. Once locked, you must use the pin every time you wish to access The Labs or the Journal. This feature is meant to give an extra touch of security to your hard-worked recipes, potentially protecting them from snoops, rivals, or curious toddlers. Make sure you don’t forget the pin! This is an offline app and password recovery is not an option. In case you do forget it, going to Paid Options allows you to disable the lock setting for a fee. (See paid options section.)

Important notice: the lock feature is not foolproof security. It is intended as a basic precaution which works best against those with limited technological knowledge. The most effective security remains protecting access to your device in its entirety.

Opening or closing drawers, adding drops, turning pages, and sliding the clipboard up and down each triggers an appropriate sound. Turn it all off by disabling this setting.

This app currently supports English and French. More languages may be added in the future.

The Export menu option allows you to

The Import menu option allows you to

The Get Transcript menu option allows you to

By principle, no finished formula can be permanently deleted. Likewise, no oil that was registered as an ingredient to a formula can be deleted either. Since this can become inconvenient when trying to keep things tidy, you have the option to set formulas and oils aside into the archives instead. Archived items can be recovered at any time.

If you ever add the wrong drops to a formula by accident and there's no up-to-date backup to fix it, you have the option to undo the mistake for a small fee. Simply go to the Paid Options section and tap the Formula Drop Undo. Then, select the name of the botched formula and a popup will tell you exactly which drop addition will be removed. Once you proceed, a transaction screen will open to complete the purchase. Once the purchase is complete, the accidental drops will be reversed. You can use this feature as many times as you need, the first ever transaction being free!

If you're an experienced perfumer, you might have your own preferences when it comes to note classifications. You might, for example, typically treat lily-of-the-valley as a top note instead of a middle note, as the app does by default. For this purpose, we offer the advanced option of modifying default notes for a small fee. Simply go to the Paid Options section and tap the Edit a Default Note. Then, select the note you wish to edit and make the necessary modifications. Once you confirm the changes, a transaction screen will open to complete the purchase. You can use this feature to edit as many defaults as you like.

Keep in mind that only the note in your currently selected language will be modified. If the app's language is set to English, for example, the French version of that note will not be modified. This feature can come in handy if you ever wish to change the modified note back to the original.

As previously mentionned, if you ever forget the password to your lock, there is no way to recover it. You can, however, bypass the password and remove the lock entirely by going to the Paid Options section and tapping the Reset Your Password. Once you press the reset button, a transaction screen will open to complete the purchase. Once the purchase is complete, the restricted sections will be unlocked and you can set a brand new password (or opt out of the locking fonctionnality entirely.)
