Baseline: Skincare Tracker
Skincare routine tracker for Android
Find out whether your skincare is working.
A skincare routine tracker and journal: progress photos you can really compare, one product tested at a time, and your own ratings on day 28, 56 and 84.
What Baseline does
A skincare routine tracker and journal: progress photos you can really compare, one product tested at a time, and your own ratings on day 28, 56 and 84.
Photos that are actually comparable
A face outline lines every photo up with your first one, and Baseline checks alignment, distance and light before you take it. If the light is wrong, it says so instead of guessing.
Checkpoints on day 28, 56 and 84
On day 0 you take a photo and rate five things yourself: oiliness, breakouts, redness, texture and dryness. At each checkpoint you do the same again and see it side by side with day 0.
One change at a time
Add a new product and it becomes the change being tested for 28 days, with a countdown. Add a second one mid-test and Baseline warns you, because two changes at once can't be told apart.
A diary for everything else
Flares, periods, travel, sun, illness, stress or poor sleep: tag the day, so you know what else might explain a change before you blame the serum.
A closer look
A measuring tool, not a diagnosis
Baseline records what you use and what you see. It never scores your face, and it never pretends to be a dermatologist.
- Photos stay on your phone, and go to your own Google Drive only if you turn backup on
- An account is optional, and it syncs text, never photos
- Ads are never shown your skin data, and only appear on two screens
- See everything it holds in one place, and delete it all from inside the app
When people reach for Baseline
Someone starting a retinoid
Retinol or adapalene takes weeks to show anything. Photos and ratings on day 28, 56 and 84 show what actually moved, and the routine check warns about acids on the same night.
Anyone who keeps switching products
A new cleanser, a new serum and a new sunscreen in one month, and no idea which one helped. Baseline tests one change at a time for 28 days.
People with sensitive skin
A 48-hour patch test timer for each new product, with a reminder to check behind the ear or on the jaw before it goes on your face.
Someone seeing a dermatologist
Months of comparable photos, your own ratings and a list of what you used when, instead of trying to remember at the appointment.
Anyone with a crowded shelf
Open dates and use-by reminders, so the vitamin C opened last spring doesn't quietly go off in the cupboard.
How this differs from most skincare apps
| Most apps | Baseline |
|---|---|
| Scores your face with an AI and calls it your skin age | Never scores or grades a face. You rate five things yourself |
| Uploads your selfies to a server | Photos stay on your phone; backup goes to your own Drive, if you choose |
| Every product change at once, no way to tell what helped | One change at a time, tested for 28 days, then a buy-again verdict |
| Warns that vitamin C and niacinamide don't mix | Flags only clashes that are established, and says why |
| Before and after photos in different light | Alignment, distance and lighting checked before the photo is taken |
| A streak that resets and scolds you | A forgiving streak with freezes; missing a day costs nothing you logged |
Useful within a minute
Step 1: Take your day-0 photo
Line your face up with the outline. Baseline checks alignment, distance and light, then you rate oiliness, breakouts, redness, texture and dryness from 1 to 5.
Step 2: Add your routine
Put your morning and evening steps in order and add the products on your shelf, by brand, by barcode scan or by name.
Step 3: Check in and wait
Tick off steps from the app or the home-screen widget. On day 28 Baseline asks for a new photo and the same five ratings, and shows them beside day 0.
And it also does
- A 48-hour patch test timer for each new product
- Routine check for retinoids with acids, benzoyl peroxide with retinol, and too many acids

Questions
Can't find the answer you're looking for?
Does Baseline diagnose skin conditions?
No. It records what you use, what you see and how you rate your own skin. It never scores your face. For medical questions, see a dermatologist.
Why day 28, 56 and 84?
The outer layer of skin is commonly said to renew in about four weeks in young adults, and more slowly with age, so most products need at least that long before any change is fair to judge. Each checkpoint opens two days early, and repeats the same photo and the same five ratings as day 0.
Where are my photos stored?
On your phone, in the app's own storage. If you turn on backup, a copy goes to a hidden app folder in your own Google Drive. The optional account syncs your routine, shelf, diary and ratings, never photos.
Which ingredient clashes does it flag?
A retinoid with an AHA or BHA in the same routine, benzoyl peroxide with retinol or tretinoin (not adapalene, which is stable with it), benzoyl peroxide with vitamin C, two or more exfoliating acids at once, and a retinoid or acid with no morning sunscreen. It never flags vitamin C with niacinamide, which is a myth.
Does Baseline show ads?
Free users see a banner on two screens, the shelf and insights, and only after the consent question where the law requires one. Ads are non-personalised and nothing from your record is passed to them. Pro, or the one-time Remove ads, takes them away.
What if I miss a week?
That's normal. Every seven days of check-ins earns a streak freeze, up to two saved. A missed week resets the count, but your photos, history and badges stay.
Can I delete everything?
Yes, from inside the app. Delete everything wipes the phone straight away, and can also remove your Drive backup and your synced account. You type DELETE to confirm, so it never happens by accident.
Baseline is not a medical device and doesn't give medical advice. It records your routine and your own observations. For skin conditions, see a dermatologist.

How long does skincare take to work? Give it four weeks at least
Most products need four weeks or more before any change is fair to judge, longer as skin ages. How to test one product properly, with photos you can compare.
