Anyone know of a way or an app that will keep the GPS on my phone turned off but will turn it on say every hour for just about a minute? I will be in the Alps next week for some long days and not guaranteed of charging every night too. I would like to run Endomundo and have it record say every hour so that friends in the UK can track us. The battery will normally only last about 5/6hours if the GPS is running.
I know I can turn most other things off, screen brightness down etc to save the battery

Chris
