Hi there,
recently there has been a post here about Colota and thought you might be interested in a short summary about Colota.
I am tracking my position since several years now mainly with Owntracks (and now Colota) and a simple postgres DB/table.
I am a fan of the indieweb and eat what you cook and with already some million location points collected I recognized some pattern in existing GPS trackers I wasn’t happy about:
- Battery consumption
- Duplicate points while staying in the same location for a long time
So I decided to build my own GPS tracker and called it Custom Location Tracker.
Improved battery consumption should come from disabling GPS entirely in so called “geofences” which are basically circles you draw on a map in the app. With GPS disabled in these you also won’t get duplicate points while staying at e.g. home or work.
The app is still quite new (actively developed since early 2026) but has already quite a lot of features which basically all came from user feedback. E.g.:
- Automatic Tracking profiles which apply different tracking settings while e.g. being connected to Android Auto, moving slower than 6km/h or while the phone is currently charging.
- The app works fully offline (map will not be visible then) but you can predownload map tiles from a tile server I selfhost or use your own tile server.
- You can define how locations are synced to your backend. E.g. only for a specific Wi-Fi SSID every 15min, once a day or with every location update.
Overall the app’s focus should move to be a mobile location history app. So basically Google Timeline in a mobile app which also supports selfhosted backends (as backup).
The app is fully open-source AGPL-3.0, has no ads, analytics or telemetry and only sends data to your own server (if you want to).
You can download two versions.
- Google Play store which uses Fused Location Provider and therefore uses Google APIs. Also works with the sandboxed version by GrapheneOS and microG.
- FOSS version which uses Android’s native GPS provider with a network location fallback. Available on IzzyOnDroid and hopefully someday on F-droid.
Both can be also downloaded directly from the repo.
Hi mxdcodes. I have been using your app for the past month in a sort of testing phase with Darawich. I have used GPS Logger and Reitti since October last year, which is still running, but Colota offers a lot more exciting possibilities of data collection and so I’ll probably switch across pretty soon. I got hit by the bug a while back of it stopping once entering a geofence, but I saw that got fixed promptly so thanks for all of this.
I love all that you and others who code for the (wider) selfhosted community offer, so let me say that for every person criticizing your app and all the effort you have put in, there are hopefully 1000x more of us who are truly grateful for what you and others do. I find it odd that people who are concerned about having their location history hacked by someone are actually wanting to record their location history in the first place. Seems the obvious answer is to… not track your location history with ANY app.
Keep up the good work!
Thank you, really appreciate it! Glad to hear Colota is working well with Dawarich for you so far. Feedback and criticism are always welcome. Most of it has led to real improvements in the app. A casual forum thread is just not the best setting for deep technical discussions, where context shifts quickly, everyone has a different background and nuance gets lost.
