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.)

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...

Hi! You don't have to pay if you don't want to! You can still use the free restricted version of the app. The new subscription offered in Tuner Pro is totally optional but allows you to have access to all the app’s premium features. :) Alice

Forced to Subscribe

I got this app to tune a guitar that I painted as a gift for someone. However, upon opening the app I was forced to start a free trial. Do not respond and say the subscription is ‘optional’, because it’s not. There is no way to close out of the subscription screen. When I discovered this, I decided to go ahead and start my free trial since I would be deleting the app after I tuned this one guitar, since I don’t have any guitars of my own nor do I know how to play one. When I tried to start my free trial, however, it wouldn’t let me because I didn’t have enough money on my phone for the app to steal once my week was up. I find it to be very misleading and unfair to label your app as ‘free to use’ and then force people into a subscription. To everyone looking for a guitar tuner, do not get this one if you want a free tuner. Go find a different app. To the developer, please either fix the issue of being stuck on the subscription screen or stop labeling the app as ‘free to use’.
