Thank you :)
I understand your concerns, this is something every additional app would have to deal with.
For me it is ok to have GPSLogger running all the time, I think for what it is doing it is quite easy on the battery but I do not use my phone actively that much and I am happy if it survives a day which it does.
no, that would not be a problem as soon as the other image library has an api reitti could query. It just happens that I am settled with immich and had no other needs at the moment.
If you need a specific one, drop a feature request and I will have a look.
