Is OpenDocument Reader free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does OpenDocument Reader require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is OpenDocument Reader safe to install?
We link to the exact APK published by Thomas Taschauer. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update OpenDocument Reader?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.

1. Tap the Download APK button above and save the file to your device.
2. Open your device Settings → Security (or Apps → Special access → Install unknown apps) and allow your file manager or browser to install unknown apps for this one file only.
3. Open the downloaded at.tomtasche.reader.apk file from your Downloads folder.
4. Tap Install and wait for Android to finish.
5. Open «OpenDocument Reader» by Thomas Taschauer and grant only the permissions it actually needs.
6. Revoke the "unknown sources" permission once you are done installing.
