The idea that a guitar tuner app should cost $400/year is ridiculous. This app is worth $5 one time, the subscription concept is pure scam.

So long, and thanks for all the tuneups

This used to be a free app, and I used it happily—if only occasionally—for several years. Imagine my surprise when I find out I’ll need to start paying money, and there’s apparently no free mode (just a 3-day trial; no thanks). I guess nothing lasts forever. So long, Guitar Tuner. Hope you make a big pile of cash. Now where in my gig bag did I lose that tuning fork…

What a joke

I’ve been using this app for years and today I got a notification that I need to update because it’s no longer compatible with my phone’s iOS. I update and reload the app and now it’s asking me to pay a subscription fee?? Moreover, it now only has the standard tunings included and I have to watch a 30 second add just to tune in Drop D??? What an absolute disappointment from a convenient app that I loved. If you really wanted money so badly, why not just sell the app for a one time $5 fee? This greedy ad and premium subscription model that’s dominating the app store is so disgusting. Deleting the app. You guys should seriously be ashamed.

Don’t use this

This app is complicated to use and if you cancel your subscription like I did it somehow still charges you. I got this app over a year ago used it once didn’t like it unsubscribed but it is charging my card twice the amount it should have charged in the first place. Don’t waste you’re time or money on this.

Downloader Beware! $8 a week unclear billing

I downloaded this app as it makes you think it’s free. Then I realize months later I am being charged $8 a week. No guitar tuner app is worth $8 a week. Downloader beware! My guess is that most of the good reviews are people that haven’t realized the are being charged $8 a week yet! This is a scam and they are making millions!

This app isn’t worth your time...

For anyone reading this review you cannot even look at what the app has to offer because of the fact you are forced to do a 3 day free trial or just pay $8 a week and if you do this subscription you would have to pay $417 for the whole year. If your a beginner trying to learn how to tune a guitar you should youtube the basics on how to do it then find a simple guitar tuning app instead. Thank you for anyone who reads this and DON’T DOWNLOAD THIS GAME!

Have used this app to tune my kids ukele’s. Disappointed when I opened the app only to find a subscription is now needed. Bye bye app!

Paywalls for individual tunings

Trash app, give me a break that each tuning is a payable unlock and now a subscription? How do I delete this app off the app store? Zero stars.
