Chord/Scale Identifier:
A great tool to find chords and scales that meet a bunch of notes. Dial in some notes of a melody, for example, and let FretBoard tell you, which chords and scales include these notes.

FretBoard Ultimate:
This is the "everything for free forever“ pack! You get all the current features, and everything we will release in future updates as in-app purchase for free. Never pay for a feature again.

If you have paid for the former version of FretBoard:

As FretBoard is so long in the AppStore, we released two versions years ago, the first was the free tryout version (blue icon), the other was this full featured paid version (brown icon). Now you can update to the same feature set as before following this procedure:

1) Download the old app version 2.0 (brown icon). Launch this app once.

2) Download the new FretBoard (with the new icon). Launch this app. It will prompt you to purchase the Pro version for free via in-app purchase. Yes, it is a purchase, but it is free. We need to do this, to save your purchase in the Apple keychain for the future.

3) Finally delete delete the old brown version from your devices.

4) We want to say sorry for the above procedure, but it was the only way to migrate your payment of the old version to the new code. Thank you for supporting FretBoard with your purchase. We love you.

What's New

Version 2.0.2

* Translations have been fixed
* Increase font size for iPad
* Minor fixes

FretBoard 2.0 is a complete overhaul of the well known FretBoard 1.x version. There is not one line of code that we did not inspect, optimised or enhanced. The whole user interface was refined to meet the current iOS standards and to work on all current iOS devices including all iPhones and iPads. And of course we listened to our users and added some of the most requested features. Enjoy!

If you own the former paid version, please update that one first for your free upgrade to this version!

Great up date

Crazy ride

Works great like the new look. Not confusing at all. Most complaints are not correct. Works great. Have used it on hand spring to iPad . Thanks for the hard work.



Thanks guys, got everything back I wanted on fretboard without paying more.

I see your app's 10 string instrument!


I found your app by searching with the term 'open tuning'. I'm using it with a beautifully sounding left-handed Cuatro Puertorriqueño, and it's native tuning of G4 G4 D4 D4 A3 A3 E3 E4 B2 B3. What I value most in your app is your knowledge of it's left- handed chords, which is why I consider it valuable! My music book is for right-handed players, and is a pain thinking in reverse.

I noticed the app is in need of an update, but it's still useful as it is, until it freezes. The question is- buy as is? It looks like the app is not being updated, thus I'm hesitant 😕. Reviews are pointing to other apps, but I really appreciated the extensive instrument lineup and their tuning and want to buy your app. So if you don't want to update your extensive one, perhaps now you know where your knowledge is desperately needed. No one has an app like this for a Cuatro Puertorriqueño. That is the term I used to search, and found only a Venezuelan Cuatro, useless for my purposes, since I need an app for the Cuatro Puertorriqueño. I would pay for an app for those left-handed chords. I would want to at least hear them with their beautiful native sound.

Update: I've just checked your website, and saw an update is scheduled for Sept. 2nd, 2017. Looking forward to it! 😆
