Supported Phones: GPS Trails Pro is designed and optimized for the Android phones.

Battery Life: While we optimize our code to cut down on power requirements, continued use of the GPS running in the background can dramatically decrease battery life. For longer dayhikes or overnight trips, we suggest packing lightweight battery packs to charge the phone.
