Kritus Support

Kritus helps you develop your ear by listening and playing back notes, chords and phrases on guitar or piano.

Contact

For help, email marcus@marcuslabs.ai. Please include your device model, operating system, Kritus version and a description of what happened.

Microphone access

Allow microphone access in your device settings to check the notes you play. Kritus processes microphone audio on your device without saving or uploading it.

Sound and practice

Check Kritus’s mute button and your device’s media volume. Use a quiet environment and keep your instrument within reach of the microphone.

Your progress

Progress is saved on your device. Kritus has no sign-in or cross-platform cloud sync. System backups and device transfers depend on your operating system settings.
