Works perfectly, but can eat battery

It works as advertised, no question. I used it in a 10 day trip to costa rica. I set it to record location every 1 minute. For a full day use, that turns out to be way too often and my phone battery died around 3pm... With 5min recording, things were much better. No other real issues. It doesnt really have an indicator for whether it has a gps lock, so use the maps app to get a lock before switching to this app.
