What a bunch of money-grubbing capitalists

This is literally a guitar tuner app. It shouldn’t cost money for a one time payment, let alone a subscription. This is an absolute outrage. I could not be more dissatisfied with this application. I gave it one star cause I couldn’t give zero. Karl Marx would never allow this capitalist oppression of the proletariat.

Terrible pricing

8 dollars a week? That comes out to about 416$ a year. You guys are insane for even thinking about charging that. I hope you guys decide to make the app free

Impossible to use

The app makes it impossible to use without either signing up for the free trial (in hopes you forget and they can start charging $8 A WEEK) or signing up without the free trial immediately. I understand app developers need to make money. But most tuner apps do this by locking alternate tunings, chromatic tuners, etc behind a paywall. Not the entire app. If that’s the case the app shouldn’t be ‘free’ with in app purchases because it’s literally unusable without doing the trial or paying the weekly subscription immediately. What a scam. This used to be my go to tuner app.

Changed to subscription based 👎

This used to be my favorite tuner. Easy to use and accurate. I had installed on my previous phone and it still works there but I’ve upgraded to iPhone 12 and now when installing the app it wants me to pay $8 a month to use the app. That’s horrible, considering I will probably only tune my guitar once in a blue. At this point, it makes more sense to go to the guitar store and buy me a tuner there. One time payment beats a monthly subscription lol

Paying for a tuner?!?

Are you kidding me? You want me to pay for a digital guitar tuner with a subscription? What?! Why not just charge once for the app itself and be done with it?

Only 3 day Trail before subscription

No permanent free function whatsoever. Just a 3 day trial with 7.99 a month fee for a darn tuner. Much better free apps available.
