TopoDroid is an Android app for cave surveying.
It is designed to work with DistoX and DistoX2, but can also be used without it, by entering the survey data manually.
Other devices are not supported.

Version changes with old apk.

Beta testers
Topodroid has an open beta program.
TopoDroid requires the following permissions:
    INTERNET (to install translations of the use manual)
In addition certain features are disabled if the following permissions are not granted:

If you experience problems running TopoDroid make sure these permissions are granted to the app.

DistoX important note
When you select a DistoX from a scan, TopoDroid tries to pair with it automatically.
TopoDroid has several BT connection settings: if you experience data transfer problems try setting "insecure" socket (see the user manual for details).
If you cannot find your Android device with a DistoX using TopoDroid, you should try to connect (and pair) to it using the Settings app. If even that fails you cannot use TopoDroid with the DistoX. This is not a problem of the app, but of your system implementation of bluetooth functionalities.

Automatic Station Name Assignment
It has been reported that the automatic station name assignment sometimes gets screwy.
Apparently this is a problem with the caching of the app by the Android system.
If it happens, close the app and clear the system app cache (with the Settings app).
Then restart TopoDroid.

TopoDroid and the other speleoapps are  free and ad-free,
and will remain so.

Android operating system and its SDK are fast moving on.
New hardware is needed to continue the app development
and to keep it up to date.
