FourForty 1.0.4

Imagine performing in front of a large audience when suddenly a string on your guitar slips out of tune. In such moments, relying on a tuning app may not be the most practical solution. However, with FourForty, musicians can develop the ability to accurately tune their instruments using their ears alone.

FourForty is designed to enhance your ear training for guitar tuning. By playing a note and determining whether it sounds sharp, flat, or in tune, users can refine their auditory skills through focused practice. This approach fosters the goal of enabling musicians to tune their guitars independently of electronic devices.

The app is equipped with a variety of features:

• Intuitive and user-friendly interface
• Training mode that challenges users to identify tuning discrepancies
• Standard guitar tuner option for those who prefer a quick assessment
• Progress graph to track improvement over time
