Better - Still Room for Improvement

I appreciate the developer taking the time to re-do the app. I like the format and the way the chords are displayed. I play guitar and noticed that the common ways to play some of the chords are deeper in the options. They should be the first option displayed. Keep up the good work. Hard to complain too much when an app is free.

Hi, sorry I’m a bit late but thanks for this feedback!

I agree that there were some issues that I’ve hopefully fixed in the latest version. All the chords are generated by an algorithm (since I want it to work with any instrument -!; tuning combination imaginable) and sometimes it got a bit mixed up, I’ve put a tonne of improvements into it now and a bunch of tests to check for errors.

I’ve also tried to have it sort them with the easy, common ones first in the new version, although sometimes a few which are impossible to play will slip through, which I am working on filtering out.

If you’re still interested in using it then drop me a message if you have any other comments!

As a dual musician I have never found a more functional app for chording charts that I could use and have that same information in a different format for another instrument! This is the only app you need, no switching between apps anymore!

Thanks so much for this review!! (I know it was 3 years ago). I’ve just got round to releasing a new version with quite a few improvements and will be making a few more in the coming weeks. Drop me a message if you’re still using it and have any comments!

Too many wrong chords

Too many wrong chords make it entirely unusable

Thanks for this feedback, (I know it was a long time ago), I’ve just released a new version though with a lot of improvements if you’d like to try it!
