## What is Fretter?

Tired of all those chordfinder apps that just give you the standard results every app gives you? Fretter is the new kid on the block. And it's great. Ugly, but great! 

We didn't sit behind our computers typing in all those chord diagrams, no we spent our time better. We came up with a way to give you lots of great correct diagrams, without needing us to do boring stuff: Fretter teaches your iPhone basic musictheory and with that knowledge it has the power to give you every possible diagram there is. Want to see how to play Cmaj7/F# on a Guitar with a Dropped D tuning? Fretter knows how to search for it! (We didn't try, but if it's possible to play, it will definitely show up. Yes, we're lazy. :) )

Still, Fretter is great. And it does awesome stuff like reverse chord lookup (for the creative geniuses among you), and you can also strum the diagrams to hear how they sound. Easy if you want to find the perfect sounding Dmaj9 or whatever strange chord you need!

So, what are you waiting for? Fretter!

For a more formal description, please continue reading.

Looking for ways to play all those chords on your guitar, banjo, ukulele or mandolin? Interested in a reverse lookup function? Fretter: the ultimate chordfinder!

Fretter doesn't rely on a database with diagrams, instead it calculates all the possible diagrams for a given chord/instrument/tuning combination. It's algorithm is optimized to only present to you the chords that you can actually play as a human.

Because Fretter is build this way, you can select any tuning and still have all the possible chords presented to you.

You can easily select a basic or advanced chord, optionally with added bassnote, and go to the diagrams. Each diagram has extra information about the chordnotes and the intervals used.

A very nice feature is the audio playback. You can hear how the chord variations sound so you can easily select which variant you like the most.

Also included is a reverse lookup option. Nice if you are a bit adventurous and you are coming up with your own chords on your instrument, but don't know how they are called. Fretter can help you here by providing you with the correct naming.

If you are looking for a chord reference app: this is what you need.

"Where this app stands out though, is not in its vast reference of chords; it is in it’s reverse look up option."

### 5/5 — Helpful and flexible

*2026-02-18*

This application offers finger shapes for chords on a variety of instruments including guitar, ukulele and mandolin.  Multiple options appear for forming chord shapes up and down the fretboard (for the type of instrument you select).

In addition, a particularly handy feature is the reverse look-up.  On an image of your instrument's fretboard, you can indicate finger positions, and let the app identify one or more names for the chord shape you've indicated.

### 5/5 — Powerhouse

*2026-01-13*

Love it. Use it constantly. Simple, clean UI. Super configurable with multiple instruments, alternate tunings, reverse chord lookup, I love this thing. It’s not been updated in years but I still use it daily. Only wish it contained sections for each musical key that included diatonic sets, commonly used out of key chords, and scales/modes.

### 5/5 — Fantastic App

*2024-09-08*

I tried the free version, then bought the paid one less than a minute later. I wanted something for noting down chords when I was coming up with guitar parts, and the Reverse Finder feature is amazing for this even in alternate tunings.

Thank you to the developer. Great App.

### 5/5 — Wow!

*2022-03-30*

Just got this app and I love it already. All kinds of options, chords for different instruments, different positions for chords, and you can even put your own positions in manually and see what that chord is.

### 2/5 — NOT ABLE TO VIEW IN LANDSCAPE ON IPAD

*2020-06-14*

The app features are great, mind you, but oh so annoying to read in portrait when my accessories are in landscape.  How difficult would that be?

### 5/5 — Best chord app out there!

*2018-06-24*

This is my go-to chord finder app!  I never use my old chord books any longer.  The reverse chord finder is awesome.  You get multiple voicing for each chord and also you can listen to how each sounds.  I highly recommend this app for any level of guitarist.

### 5/5 — Just what I needed :)

*2013-07-04*

I have been looking for an app like this and this one is perfect. I can tap the board to put in the cord I'm playing and it tells me the cord. As a bonus the look is pretty cool and I plan to copy and paste it onto my sheet music so it's easy to follow. I also like the fact that you can use different tunings and capo too!!! Pretty sweet.

### 3/5 — So so...

*2012-12-31*

Good enough chord finder - appreciate the intelligent algorithm and all - but the reverse chord finder is pretty flaky on guitar and ukulele. In standard tunings it wouldn't find single string chords like C on the uke, nor some basic chords like Am on the guitar. Not confident that it would accurately name chords correctly at all in open tunings (which I use a lot). Upgrade, please, to earn more stars.

### 5/5 — Buy It!

*2012-12-13*

Get the paid version.  Reverse finder crash bug is fixed.   I just did a bunch of reverse lookups tuned 1/2 step down, with drop-Db.  Handled it no problem.  You can even strum the chord to hear what it sounds like.  Two updates since September, so they keep it fresh.

### 5/5 — Amazing app!

*2012-04-06*

Best guitar app everywhere! Helped me so much with my first year of jazz band and I had to learn all these crazy chords. Fretter had them all!! Every guitar player should own this app. Well worth the $2!
