## What is insTuner?

***Featured on Apple's "New and Noteworthy","New", in US, UK, Australia and many more stores.***
*** Featured by FWA Mobile "Mobile of the Day" ***

insTuner is a chromatic tuner that helps you tune instruments quickly and accurately. It also features a Tone Generator just like a pitch pipe with four different wave forms. 

With advanced DSP (Digital Signal Processing) algorithm, it is highly accurate (±1/1000 semitone or ±0.1 cent precision). Rather than providing only one mode like other tuners, insTuner supports different tuning modes applicable to different situations, such as Instant Tuning Mode for quick tune and play, Fine and Strobe Modes for accurate tuning, FFT Mode for sound analysis etc. What's more, many advanced features are provided such as Concert A calibration, historical temperaments and transpositions, which make it more powerful than other tuners. 

insTuner is well-designed and easy to use. It features a unique "fixed" note wheel, which helps you to find the position of detected pitch easily. You can also use it as an electronic pitch pipe to tune by ear, matching the generated tones. 

It is suitable for tuning acoustic or electric guitar and bass, ukulele, mandolin, banjo, bouzouki, bowed strings, woodwinds, brass, timpani and more. In fact, almost any instrument that sustains a tone can be tuned using insTuner. It supports Built-in Microphone as well as Line-in and other audio interface such as Apogee One. Clip Microphone is supported too.

"Best tuner I've ever had. I'm a professional clarinetist, and I've told all of my musician friends to use this app." 

"I highly recommend this app and who can beat the price. My violin teacher compared it to her personal device. She wants an ipad to get the app for her personal use. " 

"I have the iPhone 5 and play tenor sax, I compared this to a 40 dollar tuner and its perfect..." 

"As a high school band director, I use this tuner more often than my strobo tuner. Besides the obvious portability, it is actually a bit more sensitive than the multi thousand dollar strobo and I Iove the multitude of options!"

### 5/5 — Good tuner

*2026-07-06, version 2.5.3*

Good tuner. Easy to use.

### 5/5 — Sehr universel ...

*2026-01-25*

Voll und ganz zufrieden !!!

### 5/5 — Helped tune first guitar

*2026-01-01, version 2.5.3*

So far it was free and helpful.

### 4/5 — Great for years (5 stars) but lately

*2025-12-25, version 2.5.3*

Have used (and recommended) this app for years..   a variety of useful options  with intuitive layouts , making it easy to customize the experience.     However, lately the app  consistently crashes and closes when selecting the settings icon … sometimes the chromatic tuner will crash and freeze while using.

### 1/5 — The app crashes immediately upon opening

*2025-11-21, version 2.5.3*

I purchased the pro version of this app several years ago and was initially very satisfied with it. However, the app no longer works and crashes every time I try to use it. I have attempted every possible solution and even reached out to Apple Support. They provided general advice, such as performing a hard reset of my phone and reinstalling the app. Ultimately, they informed me that they don't have control over developers and did not share any contact information for the developers. The developer's website is inactive, and I could not find any contact details. I recommend not wasting your money on this app.

### 4/5 — Pitch

*2025-04-11*

Hallo! Mir ist gerade aufgefallen: man kann zwar (per Trick) zB 441.5 Hz einstellen, gemessen wird aber trotzdem 441 Hz. Das ist schade. Kann man das verbessern?

### 2/5 — App Crashes

*2025-03-16, version 2.5.3*

I recently deleted an older InsTuner App and replaced with a new purchased version because the old version crashed as I selected the settings icon. The new version works to begin with , but eventually crashes much like the previous app.

### 5/5 — Reliable tool

*2025-01-15, version 2.5.3*

I constantly use this app when gigging or teaching.  It’s on all my mobile devices, along with the metronome by the same developer.

### 2/5 — Disappointed

*2025-01-10, version 2.5.3*

App is not working properly. Paid for the app and when I try to access the settings the app just closes!

### 1/5 — Bad update

*2024-11-10, version 2.5.3*

Crashes constantly
