Imagine you are playing guitar in front of thousands of people and suddenly one of your strings goes out of tune. This is not the time to whip out your favorite guitar tuning app but fear not! Because you have been practicing with FourForty you can tune with your ears alone.
FourForty is here to help you tune your guitar using your ears. Just play a note then guess if you are sharp, flat, or in tune. We believe with practice our users will be able to tune their guitar without a tuner. Imagine that, never having to use a guitar tuner again! EPIC!!
- Simple and easy to use
- Training mode where you guess if you are sharp, flat, or in tune
- Regular guitar tuner if you are not in the mood to train
- Graph to monitor your progress over time
