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 :)

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!

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!

Total home run

So far I’ve only used this app for two practice sessions. I’ve been working through the beginner course and now to the point of working on getting all my cord changes to 60 in a minute. I was tracking this just using the iPhone timer and pencil/paper but this app makes the whole process much more efficient so I end up getting to practice many more chord changes in the same practice session and can track the results is awesome.

Having the cord chart right there for reference is another bonus especially just starting to learn the chord I found I ended up having to refer back to the section in the book to make sure I got it right.

As someone who started with right hand guitar and switched to playing left handed I also appreciate that in the settings you can enable left handed mode so the chord charts are mirrored. I ended up not using it but I may be in the minority as to me it makes sense to look at the right handed chord chart and just flip it in my head - your results may very.

All in all an invaluable tool to add to your practice routine which is definitely not a distraction. Highly recommend this app.
