Works great but overpriced & not obvious how to cancel

First, the good - the app works really well and makes it easy to tune a variety of instruments. There are a lot of options and looks like a great tool for serious musicians, but I was just using it to tune my kids’ guitar and ukulele. Super easy to use, totally idiot proof.

However the bad is pretty bad. The weekly rate is quite high at $8/week. The yearly is more reasonable, if you know you’re going to use it a lot and want to make the investment. The thing I take issue with is that there are no instructions on the app to tell you how to cancel. However there is lots of info on this in the app reviews, which is where I found it...after spending $24 on it. The weekly price is pretty ridiculous in my opinion, and the lack of transparency in how to cancel the subscription is not accidental and in fact is predatory.

App developers, you can do better. This is a great app! There is no need to be shady!

Wow, an developer who forces you to start a free trial, UGH!

I saw a referral to this app from an ad and it looked decent to use. Unfortunately it doesn’t allow you to use FREE as offered. To even use/ test this app you are forced to start a free trial. As others have mentioned their frustration when charged the $7.99 plus tax per week and then having to unsubscribe from their service I’m astonished that Apple would allow such a setup which will cause users to have a bad experience. Users should not ever have to get into this position of having to be conned into using a free trial. The app developer should offer the app free to use with out having to finagle the situation to where a users has to waste their time to unsubscribe after the free trial is over. Why does Apple and the app develop screw users by putting us into such a position? If the app developer decides to remove this requirement that we have to use the free trial to get access to their app then I’ll give it a try. If not I’ll be posting this warning and a thumbs down for their app because of this issue. Users should not be forced to start a free trial just to test the app when it’s being advertised as a free app with in-app purchases. It’s not really a free app with in-app purchases if you force people into a situation where they are subscribed. Being subscribed is not free, it’s only free for the first week... that’s almost like a bait and switch...

Functionally Fantastic....Too Costly

I play a Hammered Dulcimer and the fully chromatic tuner function is what I was interested in. The tuner functioned fantastic, was super accurate, and was easy to use. From a functionality perspective I would give the app five gold stars. However, the weekly high cost of $7.99 sadly prevents me from continuing to be a customer. That’s a pretty steep ongoing cost, much higher than many streaming music and video services on the Internet. I could, and likely will, purchase a top of the line dedicated hardware tuner at the music store for a one time cost for less than a few months of your ongoing cost. As a retired person with a fixed income I can not justify the ongoing expense. So, due to an unusually high ongoing cost I have to give your app a seriously lower rating. Would you please reconsider your funding model to make the cost more reasonable and consider a one-time cost of about two or thee months of your ongoing fee? (Just a suggestion to achieve the five gold star rating the app should have.)
