The One Minute Changes app is a free app from to help beginner guitarists using my Beginner's Course keep track of the amount of chord changes they can do!

All the chords used in the course are built in, but you can add in your own too, see statistics and it will automatically pick the chords you struggle with most if you ask it to!

If you dig it, please check out my other apps :)

Needs some bugs fixed (new version)

I just upgraded to the new version and am not totally happy. First, it erased all of my prior scores and selected chords which is annoying, but I'll live. Second, the countdown and time-up alert sounds are waaaay too quiet now and it's almost impossible to hear them over my playing - even with the amp at fairly low volume. You had a volume slider before and if anything they were too loud, but that was far better than now. Please fix this. Thirdly, the score increase and decrease buttons don't auto count when you hold them anymore, now you have to hit them once for every count which is totally tedious. This needs fixed too. Lastly, the best score display is tiny. Why can't it just show in the score box like before? All minor things that can be addressed, but considering how much I use this app they really are annoying. Otherwise, this app has been amazingly handy and helpful. I hope to see it return to its former solid self. Thanks!

Great app that needs 2 changes!

I have been doing Justin's beginners course and this app goes perfectly along with it! It is a very helpful app to really help you speed up your cord changes. There are two slight problems with it that if fixed, the app would be perfect. The first is the screen times out before the timer ends. It would be nice if the timer would at least keep going with the screen off or if there was a setting in the app to always keep the phone on. The second is to make the cords more randomized. Some combinations always come up and others seem to never come up. However for a free app it's great and has definitely been helping me with my cord changes!

1 tiny fix = 5 stars

I want to love this app. I'm following Justin's beginner course, so this is great! Except... Every time I practice, I have to change my device's settings to keep it from going into standby. It would be nice if there was a big button right smack in the middle labeled "keep screen from turning off" or at least let the timer keep running in the background. Either one of these features (or both) would earn this great tool an immediate 5 stars. I love the app, especially for free (thanks!), but with having to change my device's settings every time I practice, and then back afterwards, I just can't give it a higher rating yet.
