## What is Piano Tuner(Home Edition)?

This is the world's first piano tuner that can accurately and stably detect the full-range 88-key pitch deviation. With the impact piano tuning lever, the piano tuning will become very simple and efficient.
The app is relatively low cost. If you have one or two pianos and want to tune them by yourself, this app is the right choose.  If you tune more pianos, the developer's Piano Tuner Pro Edition app is more suitable.
By the free app, you can detect the piano tuning curve, tune all C and A2 keys,  and experience the product actually. In addition, when a tuning curve has been detected, you can evaluate simply how much your piano is out of tune. 
After the in app purchase, you can detect all notes for tuning a piano.
The Home edition app can store one tuning curve for each piano. You can detect tuning curve any times within 90 days of purchase. After that, every 90 days you can re detect tuning curve only one time. If the piano strings are not replaced, there is no need to re detect a tuning curve.

Features:
More than 0.1 cents detection accuracy.
The Unisons Tuning mode can further help piano tuning DIY.
The Full Range mode can reliably recognize the full range pitch of the piano and simplify the operation.±6 Semitone mode is relatively faster and has better anti-jamming ability, can adapt to the sound quality is not good and the noise environment. The Manual mode has the strongest anti-interference ability and the fastest response speed.
The tuning curve can be automatically estimated with just a few keys detected.
It is more direct and accurate to display the deviation value by numerical figure. This makes there no need to keep a close eye on the display screen when a piano key is struck, and the app will keep to display the detecting result after the end of the tone.
Detection is fast and reliable. When detecting bass tone, it is only about 3/4 seconds to start showing the results. The treble tone even if the time is very short, can be accurately detected. 
Can indicate whether there is a significant beat interference.
Only built-in microphone supported.

### 5/5 — Pretty good tuner!

*2026-03-29, version 2.5*

I paid for the full version. Yes, it will crash sometimes when you update your iOS. If this happens, simply delete the app and install it again.

### 1/5 — Crashes instantly on iOS 13.4.1

*2020-05-15, version 1.96*

I’ve used this app in the past to measure my piano’s tuning, but the current version is literally unusable on current hardware and latest iOS version. Hope the developer will update quickly.

### 1/5 — Worthless.

*2019-11-21, version 1.88*

Wasted my money completely. There’s no strobe-type visual aid, only slowly reacting small numbers. Whoever made this has clearly never tuned a piano in their life.

### 1/5 — Not intuitive

*2019-07-05*

The interface is not intuitive at all.

**Developer response:** You’re right. After functional development, I really need to improve user interface and interaction in the future.

### 2/5 — Spelling mistakes throughout

*2019-04-29*

Careless

### 2/5 — I Can’t Tell What It Does

*2018-04-01, version 1.72*

The description is intriguing but when I launched the app and played note on the piano it said what note it was, but that it couldn’t do anything without a purchase. It’s is too expensive to purchase on a “gamble” that it might help me tune my piano. The description said it would tune 12 (or 13?) notes on the free app but in reality, there is a whole host of pre-settings you need to make, or the 12 or 14 notes are “secret” notes you have to discover somehow. Either way, there is no obvious way to really use the app without gambling $100.  Unless you can find someone who already paid the $100, I don’t know how you can test it.

### 1/5 — Worthless.  Don’t waste your time!

*2018-03-25, version 1.72*

Can’t seem to do anything without making a purchase.  Don’t waste your time.
