Yes! As of September 2026, there are free Apple & Android apps you can install on your home screen.
You can make a shortcut on your phones' home screen: in iOS, open up the site using Safari and click on the share button (the square with the arrow pointing up) and click on the "add to home screen" button. Make sure the "Open as Web App" option is turned on. An icon will be created that goes directly to Undebt.it.
On an Android, the process is the same. Open up Chrome and login to the site. Click on the settings dots and select the "install and create shortcut" option.
You can optionally turn on push notifications too. From the device where you are logged into the app, go to the My Account page and then to the Options tab. There is a section where you can toggle on and test out push notifications for the device. Repeat the process on each device that you would like to receive push notifications.
Note that you won't find the Undebt.it app on the Apple App Store or on Google Play. If you see an Undebt app on the app store, it is NOT mine. Following the instructions above is the only way to install the app.
