Crashes instantly on iOS 13.4.1
Response from developer
During the continuous upgrade process of this App and iOS system, under certain circumstances, this App will crash during startup. You only need to delete the App and download it again to run normally. In addition, please go to Settings > Privacy, scroll down and tap Analytics, then tap Share iPhone & Watch Analytics. In this way, developers can receive app crash reports from apple in time, and improve and repair these bugs in time.
Worthless.

I know that no matter what kind of tuner is used, someone may not be able to complete the piano tuning. So my app allows users to tune 15 keys for free so that they can evaluate whether themself can complete this task. The instructions in the app also remind the user to determine whether to purchase after tuning these keys.
Not intuitive
Response from developer
You’re right. After functional development, I really need to improve user interface and interaction in the future.
Spelling mistakes throughout
I Can’t Tell What It Does
Response from developer
I am sorry for the bad experience that my app has brought to you. The version you use does not clearly state which keys can be tuned when not purchased. Instead, you need to "discover " them by changing the key in non Full Range mode. Now, the 15 keys that can be tuned without purchase are clearly stated. These keys are all C and A keys except A4 key.
Worthless. Don’t waste your time!
Response from developer
Sorry there is no clear indication in that version which 11 keys can be tuned. The 15 keys that can be tuned without purchase are now clearly stated. These keys are all C and A keys except A4 key.
