AAT does not automatically remove downloaded map tiles. This is to...
- reduce network traffic as much as possible.
- reduce battery drain.
- speed up the map view.
This means that you have to remove old tiles manually from time to time.

Where to find files?
AAT let's you create and view files in GPX format. This files are exchangeable with many other applications. They can also be edited in a text editor. These and other files are stored in subdirectories of the data directory. You can choose the location of the data directory from the settings. The structure of the data directory is as follows:
aat_data/activity[0-4]- tracked activities
aat_data/log- activity that gets tracked at the moment
aat_data/nominatim- search result from OpenStreetMap Nominatim
aat_data/osm_features- OSM Features original file and parsed files
aat_data/overlay- overlays such as planned tracks or search results
aat_data/overpass- queries from the OSM Overpass server
aat_data/dem3- cached Digital elevation data from the Shuttle Radar Topography Mission and other sources
AAT lets you query the Overpass API. Any result of a query can be saved to
aat_data/overlay. It then can be displayed as an overlay inside the map-view whenever needed.
[amenity=restaurant] will get you list of all restaurants located inside the area that was visible on the map-view before opening the Overpass dialog.
AAT uses the formula
time[hours] * MET * weight[kg] to calculate the kcal used for a specific activity.
MET stands for metabolic equivalent. The higher the value, the more energy you would use
for this specific activity. A complete list of activities and MET values can be found here.
Both MET and weight can be provided in the settings dialog. The MET value is leading the activity's name. For example:
6.8 bicycling, leisure, moderate effort
