ThumbTrek
Today's trek
1.84 km
Thumb distance across four feeds
ThumbTrek
Strava for scrolling. Turn Instagram, YouTube, X, and Reddit into a trek — meters, streaks, share cards, and friend boards.
A trek, not a guilt trip
ThumbTrek measures distance, not doom. No blocking, no lectures — just the map of where your thumb already went.
Grant Accessibility once
The service only listens for scroll events in apps you choose. It never reads screen content.
Scroll like you already do
Pixels become meters using your screen density. Instagram, YouTube, X, Reddit — plus any app you add.
Check the board when you want
Streaks, records, shareable PNG cards, and fully opt-in friend or global leaderboards.

Built for the long scroll
Local-first storage, signed sideloaded updates, and a social layer that stays quiet until you opt in.
Self-updating APK
Checks GitHub Releases over Wi‑Fi, verifies SHA‑256, then asks once to install. No Play Store required.
Opt-in social
Friend codes, weekly boards, anonymous handles. Nothing leaves the phone until you say so.
Honest numbers
No user calibration sliders on competitive scores — everyone measures the same raw trek.
Install in a minute
Grab the latest signed APK from GitHub Releases. Allow install from your browser once, then ThumbTrek can update itself.
Android 8.0+. Sideload only — not on the Play Store yet.
What we see — and don't
Scroll distance stays on-device by default. Cloud sync is for leaderboards you choose to join.
Never read
No screenshots, no feed text, no URLs. Accessibility is scoped to scroll events on opted-in packages.
Stored locally
Day-by-day pixels live in Room on your phone. Export CSV anytime from Settings.
Shared only if opted in
Weekly / monthly / all-time totals sync to Firebase after you flip the Social switch.
