About

I am a solo Android developer, and I make LifeTrail. LifeTrail is a GPS trail recorder that runs in the background and draws your routes as a speed-coloured trail on a map. I built it because Google took the Timeline view out of Maps and every replacement I could find wanted me to run a server first. The part I enjoy most is the awkward part: foreground services that survive OEM battery managers, GPS that keeps drawing when the signal drops, and saying plainly what does and does not leave your phone. I post about the technical details and the privacy trade-offs. Ask me anything.

LifeTrail - Auto-records everywhere you've been. No account, no ads.

A private GPS trail recorder for Android. It logs your walk, run, ride or drive routes in the background, then replays them on a speed-coloured map with monthly recaps. Your trail history stays on your phone — no account, no backend of our own, no ads.
