"Offline GPS Tracker Professional" is a unique and powerful tool, which offers a lot of features, and internet connection is NOT required for this app.
The app shows and stores all GPS (respectively GLONASS) data. This data includes date, time, altitude, latitude, longitude, speed (in all popular formats: m/s; km/h; mph and kn/h), accuracy and number of received satellites. This data is saved directly in the app's internal database, which can be read and edit directly in the app. When you save the data, you can additionally also add your own notes to the data. When this app calculating you position, GPS and GLONASS (if supported by your device) satellites are combined - this results in an optimum calculation of your position.
The unique thing about this app (compared to everyone else) is that this app works absolutely offline. Other apps ask the data wholly or partly from over the Internet. This app does not. You do not need Internet connection and no network coverage to use the app. The application relates solely to the sensors of your device. Ideal for use in the field, at sea or in the aircraft.
In addition, the UI of this app has been created so, that the use of this app uses so little power as possible.
Bug fix: added text formatting for playback of saved data.
