This is the support page for Interval and Interval min. Most application problems can be solved by either restarting the device or reloading the application from the app store. If neither of these resolves your problem, and it is not addressed in this FAQ, then please email support This is our general support line, so if you email us please tell us which app is causing the problem, whether it is the iOS or Android version, and as much detail as you can about the problem.
I downloaded the app and the app store says it's installed, but I can't find the icon.
This is not an app problem, and sometimes happens with certain devices. Power down your device and then power it back up. The app icon should now be visible.
Which mobile devices are supported?
The Android version will run on any phone or tablet using Android 3.0 or later. The iPhone, iPod touch, iPad version requires iOS 14.0.
What's the difference between the paid and free version?
The paid version can be played offline and contains greater chord variation. The free version requires an Internet connection, shows advertisements, and uses a reduced set of chords.
Can I use different instrument voices to play the chords?
Yes. Currently grand piano (the default) and church organ are provided. Change the instrument in the settings (the Settings app for the iPhone, iPod and iPad version)
Why would I restart the game?
If your score was lower than you'd like because some of your answers were wrong and you want to start from the beginning again.
