💡 Costs & licensing model:
The app can be downloaded for free on this website (as well as in the Google PlayStore and Apple App Store) and can be tested extensively (the first special programs, symptoms, and experience reports accessed are permanently free of charge).
An annual license for the full version can be purchased for 20 € – directly here via our shop. Note: When you make a purchase, an account is automatically created on the website and you will receive an email with your username and a link for setting a password. To log in to the app, you will need this username (or alternatively your email address) and the newly set password.
If you would like to support the initial version and further development, you can send us a grant amount - many thanks!
💻 Availability & downloads:
- Android (tested on version 8 and later), Harmony, and others – below or via the Google Play Store (Note: Aurora as store does not work)
- Windows (tested from version 10 onwards)
- Linux (x86_64 architecture, others upon request)
- Apple-Version (iPhone, iPad, MacBook) only in the App Store
Android, Harmony and others: Download the 5bn.apk file directly to your smartphone and then run it to install the app. Alternatively, you can download and install it from the Google Play Store. If your phone doesn't have Google, use the version from our website, not the Aurora Store.
Windows: Download the 5bn_windows_setup.exe file on Windows. You will probably receive a warning message saying “Your computer has been protected by Windows” before installation, as Windows does not recognize our 5BN app (and we cannot afford to pay hundreds of euros per year for certification). Simply click on “More info” and then “Run anyway.”
Linux: Unzip the file and then, if necessary, grant execution rights using “chmod +x ./5bn.x86_64”.
