SkinStreak

Skincare advice is everywhere. Proof is rare. SkinStreak is the routine tracker that checks the ingredients in your products for clashes, keeps your nightly streak alive, and measures real change with your own photos, so you finally know what actually works for your skin.

HOW IT WORKS
- CONFLICT CHECKER FIRST: add any product and a 68-rule engine instantly flags clashes, like retinol mixed with the wrong actives, with severity, evidence grade, and a fix. It runs in under a second, right on your phone.
- SCAN THE SHELF: point your camera at any barcode to pull the full ingredient list, or type it in manually. Everything you add lands in your Cabinet.
- TONIGHT, SORTED: your evening routine appears as simple cards, skin cycling included, and clashing products are automatically separated into morning vs night.
- STREAKS THAT FORGIVE: swipe to check in each night. Missed a day? Streak Freeze (two a month) protects your streak with kind words, never guilt.
- LIGHT-CHECKED SELFIES: a guided selfie with an alignment frame; LightGuard catches bad lighting before it saves a photo that would lie to you.
- MEASURED, NOT JUDGED: redness, texture, and visible spots, including acne flare-ups, measured on device and calibrated to your Fitzpatrick type. Trends are shown against your own baseline. There is no number rating how you look.
- A SUNDAY RHYTHM: a Sunday photo reminder plus gentle notices 24 hours before a trial ends and renews.

AI FEATURES
Deep weekly scans use AI to explain your measurements in plain language. This app uses your own API key for AI features if you bring your own key from any compatible provider, and AI features are unlimited with your own key, no usage limits or in-app token purchases. Your API key is stored securely in the Keychain on your device and never sent to our servers. AI never changes your numbers; it only explains them. All measurements are computed on your device.

SkinStreak provides general wellness information, not medical advice. Your photos and measurements stay private, and you can delete everything with one tap.
