Baseline: Skincare Tracker

Is your skincare routine actually working? Stop guessing and stop buying products that do nothing. Baseline is a private skincare tracker and skincare journal: take progress photos you can really compare, log your AM & PM routine, and see what changed — week by week.

DAY 0 VS DAY 28 — SEE IT FOR YOURSELF
Take a guided photo on day 0. A face outline and a lighting check help you line it up the same way every time, so your before and after are actually comparable. Skin renews about every 28 days, so on day 28, 56 and 84 you take another photo and see the two side by side or on a slider. Unretouched — no filters, no auto-enhance.

YOUR FIRST READ
After enough comparable photos, Baseline gives you a plain-words read of what changed: fewer visible spots on one cheek, redness about the same, little change along the jaw. It tells you what it can see — and what it can't.

TEST ONE PRODUCT AT A TIME
Add a new serum and Baseline makes it "the change being tested" for four weeks, with a countdown. Adding a second new product mid-test? You get a gentle heads-up, because two changes at once make it impossible to know which one worked. At the end, decide whether you'd buy it again.

48-HOUR PATCH TEST
Start a patch-test timer when you add a product. Baseline reminds you to check.

AM & PM ROUTINE IN TWO TAPS
Morning and evening routines in step order, with amounts and wait times. Check steps off in the app or from the home-screen widget. A streak that forgives a missed day, earns freezes and never punishes you.

ROUTINE CHECK WITHOUT THE FEAR
Baseline flags layering clashes that are actually established — a retinoid with an exfoliating acid on the same night, benzoyl peroxide with retinol, too many acids — and always says why. It won't repeat myths like "vitamin C and niacinamide don't mix". Works as a retinol tracker too.

YOUR SKINCARE SHELF
Add products in seconds with barcode scan and brand suggestions: Minimalist, Dot & Key, The Derma Co, Plum, Foxtale, Re'equil, CeraVe, The Ordinary, La Roche-Posay, Paula's Choice, COSRX, Beauty of Joseon and more. Open dates and use-by reminders. Finished a bottle? It moves to your empties with your verdict.

PRIVATE BY DESIGN
Your photos stay on your phone. Backup is optional and goes to your own Google Drive. An account is optional and never syncs photos. No face is ever scored or graded.

FREE TO START — NO QUIZ WALL
Free: your full routine, shelf, every photo, one product test at a time, the day-28 compare, backup and export. Pro adds every later checkpoint, any-range compare, several tests at once, unlimited ingredient lookups, no ads — and a report to bring to your dermatologist.

Baseline is not a medical device and does not give medical advice. It records your routine and your own observations.
