Helpful 🤗👍🏼

This is really handy as my guitar tuner has broken and I have tried an other app and it picked up my third string as a second string. It is easy to use and understand I DEFINITELY RECOMMEND FOR YOU TO TRY👍🏼👍🏼

Excellent BUT far too expensive

Excellent app. Easy to use. Accurate tunings. Wide alternate tunings.
Only drawback is the prohibitively expensive unlock price, which is literally 5X what it should be. I would have rated this app five stars if the price was reasonable. It is literally far cheaper to buy a hardware tuner than unlocking this app for a few months. Twelve months of subscription could buy a new guitar with a tuner onboard.

Forced Subscription

Really enjoyed the app until it randomly forced me to sign up. The app is labelled free but it is not! You can’t use any of the features without a subscription. I understand the developers need to make money but forcing a user to pay for a free app is confusing and false advertising. I honestly would pay for the app if it wasn’t done in such a sly manner. The app is perfectly fine but the selling tactics should be reconsidered.
