I want to be reminded to give back 2 dollars to Joe next time I pass near his home.
Is there an Android app for that?
- Let me define an alert with a text, a latitude/longitude chosen on a map, a radius.
- Open source, because I don't trust any proprietary app with my location information.
- Don't consume too much power. Probably the hardest part. Recognizing Wi-Fi networks could be a workaround: I create a few "known places" (for each of these places, the app stores the list of Wi-Fi networks available at that place) and can use them later for alerts without activating the GPS.
- Preferably using OpenStreetMap data, but other maps are OK too.
