tower

• no Google Services dependencies, only necessary permissions (fine and coarse location, internet, foreground service)

• connects to several online map providers

• acceptable performance on slow GPRS-EDGE networks; may find coarse location by phone cell without GPS; may create waypoints with GPS without phone and internet connections

• displays and saves cell info ( MCC, MNC, LAC, CID ) and the signal strength ( RSRP/dBm )

• all waypoints are stored on a memory card and may be organized in any number of files (by regions etc.)

• waypoint lists may be exported or imported in the GPX format, compatible with many navigators and software

• finds location only by explicit user's command, so is very mild on the battery

• capable of writing tracks (by means of a foreground service) and exporting them in the GPX format

• tracks from other devices (GPX files) may be viewed along with your data

• NOT implemented: map offline caching, routing, editing tracks, photo and video attachments, serving cold beer :)

• for pure open distributions, that lack API keys and access to some services, there are options to enter user's own keys
