Hands-free tuning for guitar, ukulele and other musical instruments. Designed for novices and pros, fully featured, easy to use. Pro features are split into low cost upgrades so you can build your own tuning experience and buy only what you need.

Unique features help you work out the chords to new tunes, visualize the pitch and consistency of the human voice, violin or other instrument, or answer the questions "what notes am I humming", "what are those chords", "am I hitting all the notes in tune", "is my vibrato consistent" etc.

Multiple visualization modes:

Instrument: Combination chromatic ribbon tuner and string/note display for easy instrument tuning. Includes standard Guitar tuning for free with a custom tuning editor and database of common tunings for Guitar, Violin/Fiddle, Mandolin, Ukulele, Banjo, Bouzouki and Pedal Steel available as an upgrade.

Stage Tuner: A large, clear tuning display, optimized for hands-free operation at a distance and incorporating a true radial and waterfall strobe for unbeatable fine-tuning accuracy and responsiveness. Tap the display to change modes.

Chord Matrix (upgrade): Grid-based estimation display of common chord types (maj/min, maj7/min7, dom7/dim7), ideal for quickly determining the 'strum along' chords for a tune where the chords are reasonably clear.

Pitch Spectrogram (upgrade): Scrolling display of live sound analysis, showing the perceived pitch of a wide range of sound types (including human voices and singing).

Tone Generator (upgrade): An 8-octave, polyphonic keyboard display that enables you to play reference notes in the musical scale. Includes a selection of tone waveform types and the ability to quickly switch between single-note or multi-note mode.

Strobe Tuner (upgrade): A true 6-band, multi-mode strobe display combined with a chromatic ribbon tuner for rapid and extremely accurate hands-free instrument tuning. Tap the display to change modes.

Split Screen (upgrade): Split the screen and use any two tuning views at the same time (e.g. Pitch Spectrogram plus Chord Matrix for transcription work). Please note, this upgrade is only recommended for tablets or devices with large screens and only for users who have purchased one or more tuner view upgrades.

These visualization modes are easily accessed by swiping the screen left/right (or up/down, depending on the screen orientation). When available, split-screen mode is enabled/disabled by pressing a toggle button on the main display.

Best tuner! But getting old...

Don't let the "guitar" in the subtitle fool you: this is an awesome tuner for any sort of string player, keyboardist, or wind player. I use it to tune harpsichords and organs in all sorts of temperaments. It's extremely fast and accurate (see below for caveat).

The only issue is that on newer iPhones the dial marks "in tune" as being 1.5 cents sharp. (It even reads its own produced sound as sharp.) Otherwise an awesome, awesome app.

My favorite feature WAS that you could plug in headphones and play a reference tone while it also listens through the microphone. BUT PitchLab does not support headphones through lightning adapter or Bluetooth (like AirPods) so this feature no longer works on newer phones.

I wish wish wish the developer would modernize headphone support, fix the 1.5 cents sharp offset, and for good measure add the clock back into the upper corner. But I still haven’t found a better app around. I’m looking...

The app is now so old that none of my current devices are 100% compatible. I still haven’t found any app that fully replaces it, but I’m sad and frustrated. I would pay for an update in a heartbeat!

Started out great. Now what?

I can see the developer gave up on this awhile back. Too bad, originally it worked really well. 3 issues for me, in chronological order:
1) I paid for the app for the VU Meters tuner. 12 individual VUs that we’re awesome. One day they were just gone without warning, never to be heard from again.
2) Years after buying and using the app daily, yesterday I had to restore my iPad, which I’ve done to phone and pad many time since buying this app. Upon reinstalling and opening I get MICROPHONE ACCESS FAILED. ALLOW ACCESS IN SETTINGS. Cool. My other tuner is in the list and allowed. This one won’t appear, so now what? I’ve reinstalled, reset, reinstalled, reset, etc... It ain’t there. Dead in the water.
3) Now I see there is no support or working contact for the developer. It’s a shame because I liked this and recommended it often (always explaining that the best of the tuners disappeared without explanation after he took my money).

My fave tuner but stopped working

As others have reported, this tuner is awesome if it works on your phone. I recently upgraded to ios 13.1 from whatever was running on my iPhone 8 Msx and it stopped working. I get an audio error saying that the microphone must be enabled but it's already enabled in my privacy settings. This is different than what others are reporting where they get the error message but can't actually find the app in settings to enable. I really really miss using this app. It was a highly accurate and really visually appealing way to tune my bass. Too bad.
