About this app
GUNR - Data On Previous Engagements is a place to save information of previous visits to the range, training, or engagements. Gather information so that you can re-apply it in future when facing the same conditions. Verify ballistic data provided by other apps, by capturing your D.O.P.E. when on the range. Capture Distance, Wind Direction, Wind Speed, Slope, Time of day, Weather conditions, Notes, Photos, Windage and Elevation by using the device's sensors, or by entering it manually. Use the app for free, or gain access to the filters by buying a subscription. Real time filtering by entering ranges for Distance, Wind Direction, Wind Speed, Slope, Temperature, Humidity, Pressure, Notes, or Location name. View all captured values in a table, or go to the detailed view for more information on that entry.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
Price tracking
Price intelligence
