The shooting line has no signal. Everything works without one; sync is a convenience, not a requirement.
Arrowdex is an archery training app for archers who take their progression seriously. Made by one developer in Bottrop, Germany.

Paper scoresheets crumple in the quiver, sight marks live in a notebook at home, tuning notes on the back of a receipt. Arrowdex puts all of it in one place, on the shooting line, offline.
It started as a tool for one archer and grew into a training companion for clubs and coaches: plans, mental training, matches, leaderboards. The goal stayed the same: understand what your numbers actually mean.

Built in Germany under GDPR. Analytics are anonymous and opt-in, export is one tap, deletion is in the app.
Numbers read like an instrument: exact, plain, without cheering.
Recurve, compound, barebow, longbow and traditional, each with the tuning, divisions and words it actually uses.
If it’s on this page, it’s in the app today. Nothing promised, nothing mocked up.
The log is free for good. Pro covers what costs money to run: servers and sync.
