Built for Android

Native Kotlin. Material You. No middleware tax.

On-device TensorFlow Lite

Hair Score runs locally with NNAPI acceleration. No upload, no cloud round-trip, no exposure of your photos.

CameraX alignment

Frame-to-frame alignment uses CameraX with depth and exposure metadata for sub-pixel registration.

End-to-end encrypted backup

Optional Google Drive backup is encrypted on-device before upload. We hold no decryption keys.

Material You theming

Dynamic color picks up your wallpaper palette. Light, dark, and high-contrast variants ship by default.

Tasker and Routines

Trigger your weekly capture from Tasker, Routines, or a Quick Settings tile. The phone handles the rest.

Foldable-aware UI

Optimized layouts for Galaxy Fold, Pixel Fold, and tablets. Timeline and Hair Score show side-by-side on the larger screen.

Android questions, plainly answered.

Which Android phones are supported?
Folicle requires Android 12 (API 31) or later. That covers most Pixel, Samsung Galaxy, OnePlus, Xiaomi, and Motorola devices released in the last three years. We test against Pixel, Galaxy S, and OnePlus reference devices each release.
Does it require a Pixel or Samsung flagship for the Hair Score?
No. The on-device model runs through TensorFlow Lite with NNAPI acceleration where available, and falls back to CPU on older hardware. Hair Score quality is identical across supported devices, only the inference time differs.
Is there a Google Play page yet?
The Android app is in pre-launch. Join the waitlist and we will send you a Play Store internal-testing invite when your slot opens, and a public Play Store link the day we ship.
Can I switch between iOS and Android without losing my history?
Yes. Both apps share the same data model. Sign in with the same account and your zones, photos, treatments, and Hair Score history sync over end-to-end encrypted backup.
