JamBox - the musicians app for chords and scales on stringed instruments.

Specify a chord and the app will provide you with extensive information on fingering, handle lengths, the notes contained in the chord, blank and muted strings, Barrée sizes supplemented by the music-theoretical groundwork such as scales and intervals. In addition to various stringed instruments, the output of the desired information can be influenced by individual parameters such as own string-tuning and max. fret width. JamBox is not data-based - it calculates all the information on music-theoretical algorithm. By that JamBox Pro is even more flexible than the tension of your strings!

Almost perfect I've tried many scale apps before but this one shows all info I need on a sgs4 screen. I'm rating it 4/4 as I think it can be improved by allowing color changes for the root and intervals. Also the fretboard could be a bit larger which could be accomplished by removing the bottom line which shows "chords and scales"

Eugene Galyaev

Just got repaired Working great on Sony Xperia Z. Thanks

Bart Rabelo

Working Fine Again Working perfectly on Android 4.4.4, thanks for the update.

Morgan Cummins-Hussey

Glitchy and unstable. Have been using the light version for a while and loved it. Thought I'd upgrade but this just gets stuck all the time and glitches. Will give it a while longer to see if it can be fixed. Also being able to scroll across and zoom in on the fret board would be fantastic.

James Ellis

Getting refund. Bought this because of the banjo, but it only has 4 string banjo for some odd reason. When you include 5 string banjo with lots of tunings, I'll consider buying again.

matt shade

Good tool for guitarists This app needs the option to lock the screen in landscape, and an option to save custom tunings. Add more scales please.

A Google User

It could be great, but... It won't even open with the new kitkat os!

Julian Jones

Desperately needs fixing! Works fine after first install but when you come back to it nothing works at all. Considering I paid for this one thinking it would be the best I'm very disappointed. Please fix!

Lőcsei Bence

Needs fix I love that you can set the instrument, I need that, but unfortunately it won't start on my Nexus 10. I don't want a refund, this is the best scale app I found, but a fix would just be fantastic.

A Google User

good but would be best! I used to start singing with the shaking of the phone with jam box, so sad to not to see that feature.

Richard Curry

Don't bother Won't open now. Says it unfortunately stopped. I want a refund!

Caleb Heights

A Google User

Helpfull App For beginners and novices who do not have a good knowledge of music theory

Cesar Barragan

Freezes! It's freezing on me! Please fix! I paid for the app.

Riff Raph

Too many glitches Too many glitches just get the free one it's better.

Gary Gagosian

Stopped working no support This would be good app if it stayed compatible with the latest android version. My app stopped working on my Nexus 7 and Nexus 4

A Google User

Somethings wrong though Worked for a while, now freezes when "calculating variations" droid x

A Google User

The lite version is better Going back to the lite version. It's faster and the interface is better.

A Google User

Horrible App constantly freezes on calculating variations. Even if it works it takes so long that I can figure the chords out manually. Is it so hard to build a cache of the most used scales and chords so we don't have to wait? Your programmers should resign and go back to dishwashing.

Ran Ross

Will Not Open Jambox Pro won't open on Android now. It used to work fine. Please fix! I get an error message stating "unfortunately jambox has stopped" Edited comment for accuracy.

Mark Bishop

Missing key components In open D tuning the chords displayed is virtually nil. In banjo mode it is missing the simpler chords such as D7 in the first position. For an app that calcilates the chord shape and scale it is lacking for what I required. The cost was cheap but needs some major work.

Cesar Acosta

It's great I would love it if u can look up arpeggios on this app other then that it would be great

A Google User

Another winner Awesome app! Just would be nice for it move to SD. Probably a future feature.

A Google User

Avoid! Have to clear catch every time just to use. Asked for a fix with no reply. They took my money quickly. When it works it is slow. Wish it was fixed. But no luck. Avoid it. Save your money.

Myles Chapman

Problems Stuck on 'please wait, calculating variations'. I'd like my money back!

A Google User

Better than the free version

Michael Baker

Won't open on my HTC One! Please fix! I'll re-rate when I can actually use the app. I have now payed for something I can't use...

A Google User

Promising Looks to be a great update. Seems like the developer has some exciting things planned.


Same problem new user I think this might have been a great program, but it has serious problems - like it never works. I bought the app and it never worked. I got a black screen and was never see the UI. I wonder if INTERMED GMBH will fix their app.

A Google User

Uh Freaking May Zing THIS is what I have been looking for! This is the best app ever! I LOVE IT! It's so incredibly helpful to me to find a scale or a chord--I can do it in a snap. Amazing app!
