User reviews

Does not display correctly in horizontal mode…

…which is how I use my iPad. Other than that, I agree with everything Steve8pi wrote. This is an elegantly designed app. I want to give it 5 stars. But, the text overflow in horizontal mode, while it doesn’t make it unusable, is irritating to an eye.

Great Tool for Musical Inspiration

This is a handy tool to inspire chord progressions, and quite informative, as well. It’s easy-to-read and comes in quite handy when I’m stuck on a song. The Turnarounds are also helpful; I don’t believe I’ve seen them offered elsewhere.

For efficiency's sake, I do wish audio was also provided; but it’s not a dealbreaker at all. At this price for such a solid app, why complain?

Nice reference sheets

Handy reference sheets for chord progressions. Don't expect it to play music. That's your job. This is purely a compact but comprehensive reference tool. Works well on my iPad. Has many progressions organized well. My only suggestion for developers would be to use lower case for minor keys. Instead of "I-V-II", use "I-V-ii". I think that's more common.
Thanks for a useful app!

Response from developer

Thank you for your rating.

Not good enough

Sorry, but for 99p this is not good enough, just a list of chords. No way to play them to try them out, nothing. Just a sheet of chords depending on what scale you choose, nothing you can't get on the internet for free. Doesn't even tell you what notes are in each chord. Pathetic

Response from developer

I'm sorry the app wasn't to your liking. The Prog Machine has no sound. It is specified in the app description in the App Store "There are NO MIDI or AUDIO FILES.” This app was designed to show a huge amount of chord progressions on screen. In fact, this offers the largest amount available in a mobile app.
