Dear Yousician team,

I am writing to request that you consider adding a feature to your app that allows users to evaluate the condition of their guitar strings. It would be very helpful if the app could:

Provide an assessment of the lifespan of guitar strings
Indicate when it's time to replace the strings
Provide information on the quality of the sound of the strings
It would be great if you could include this feature in the Yousician app, as many musicians use your platform to learn and practice guitar.
