lavatories VS gpslogger

LavSeeker: LavSeeker shows toilets listed in OpenStreetMap

For location history I use https://gpslogger.app. It's open-source, can be found on F-Droid and has many settings.

I realize tracking takes some battery life. But I already run two GPS trackers on my phone (Google Maps tracks location, also I have GPSLogger. They both use a very small amount of battery. Eufy is using a lot more.

Or you could use a more efficient GPS logging app. eg GPS Logger. https://gpslogger.app/ It has settings you can adjust to save power, eg reduce the frequency of recording points. Then you can export a GPX file afterwards to upload to Strava.

GPSLogger (version 127): A lightweight GPS logger, battery efficient, GPX/KML, add notes, share, upload.

Haven't used strava or komoot and my answer probably is too late, sorry. But I personally used "GPSLogger for Android" on longer trips. Works pretty well, you have several options to tweak the performance and therefore your battery life.

I like GPSLogger for Android to log the trip to GPX https://gpslogger.app/ but haven't found anything I like to save it visually

My method, FWIW, is to attach a small Bluetooth device to the bike (I have a speaker, but anything you can power on or off works). I have an Android phone with Tasker and GPSLogger, and I have a Tasker profile which starts logging when it connects to the specific Bluetooth device, and stops logging when it disconnect. It's a bit of a janky setup but it does record my rides pretty consistently without having to actually handle my phone.
