This page is the only official point for TopoDroid download:
Latest
TopoDroid v. 6.1 can be installed side by side with the obsolete GooglePlay version, 5.1.40.
The GooglePlay version will not be updated, because TopoDroid will not satisfy the GooglePlay
"security" (access to file system), and "deployment"
(signing by Google) requirements.
From Nov. 2022 the app on GooglePlay will not be available to Android 11 and later.
On Android-11 and later you must grant the app access to storage: instructions
The app base-folder is Documents/TDX.
Survey data are in the subfolder Documents/TDX/TopoDroid,
which contains the TopoDroid database, and a folder for each survey.
It has also the folder for the project files thconfig,
and the folder for zip archives.
Each survey folder contains the files of the survey: sketches (tdr),
images, etc., and the exports (out).
The app files (drawing tools, log-file, firmwares, resources,
and the device related files, including the device database) are in the app
private "Files" folder.
Zip archives of old TopoDroid surveys
can be imported in the new TopoDroid folder with the "import" function.
Error reports and feedbacks are welcome: include app version and Android version.
For bugs include also the output of the command "adb logcat | grep topodroid".
Note. Translations with more than 60 untranslated strings are
dropped from the app, until they go below 20 untranslated strings.
To verify the integrity of the app, check the MD5 sum before installing the apk:
