About Alpi Maps
Alpi Maps is an open source map app for iOS and Android. It is designed to help users plan a hike in advance and then use map data offline during the hike. The app is based on OpenStreetMap data and offers many map styles and overlays, including ski trails. It also manages GPS to provide a precise location when needed, with the stated aim of keeping battery use low. The source notes that continuous background GPS use can greatly reduce battery life.
The default vector map source, AmericanaOSM, is not provided by the developer. The developer stopped a shared free instance after it exceeded its usage limit. Users who want this source must set up their own instance through an AWS account, using the CloudFormation template, the us-east-2 region and the bucket name described in the source. On Android, offline map data is expected in an SD card folder named alpimaps_mbtiles.
