  • Useful but annoying.

    By Perktimus
    The different tunings and instruments are great! When you have tuned all the strings, a loud sound and “congrats!!!!!1!!!” screen appear, which is actually kind if annoying, because sometimes you want to go back and fine-tune strings. What is considered in tune by the app can be quite noticably off.
  • Stupid trial

    By emgaming445
    I’m disappointed in this app because u have to pay a LOT of money. I just want to enjoy life and play my instrument but I have to pay just to tune it!¡

    By mmmmm,mm,mm,mjjjfffff
    Don’t click unless you want to be charged a membership fee of 1x per WEEK. it took me 2 hours to cancel after being sneakily charged $8+ a week!! Don’t download this app
  • This app requires $8 per week to use. Don’t download. 1 star is too many.

    By satls
    The ui and features of this app are unusable without paying for an $8 per week subscription. I feel upset that apple even allowed this app on the store and that it was at the top of the list for tuners. I would give this app negative stars if I could.
  • Rip Off

    Way too much money for this app. It starts free and then they charge like eight dollars a week if you don’t unsubscribe. Problem is I can’t figure out how to unsubscribe. They don’t make it easy. If anyone can help me I would appreciate it.
  • Unethical!!!!! Do NOT touch the “get” button!

    I echo all the other recent ratings that warn to steer clear of this app.
