Guitar Scales Power will help guitar players at any level learn many of the most commonly used scales and modes. Stay in tune with the tuner and enhance your playing skills by mastering scale positions in any key.

Practice playing with scale position loops to perfect the position and build muscle memory. Learning scales will boost your finger dexterity and ability to improvise. Start slowly and increase speed as you progress.

Play scales by swiping across guitar strings; the direction of the swipe determines ascending or descending playback. Play scale position loops by tapping the play loop button. Tap on a note to play it.

Scale positions correspond to the CAGED system, which consists of five patterns that cover the fretboard for each scale. The chord shape for each position is displayed to assist you in learning it in any key.

The tuner offers a chromatic mode or the option to select from various tunings.

The tuner and instruments use an adjustable reference frequency, set to 410 Hz - 470 Hz (default A = 440 Hz).

Rosemarie and Chuck ,

I don’t recommend, bought app, didn’t buy adds!

So I gave this free app a bad review because it came with adds but it was after I purchased Guitar Scales & Chord Power. I didn’t realize the picture in the icons were identical and I was opening the free version with adds. So the developer was kind enough to reach out to me and suggest I delete the free version and how to tell the 2 apps apart. The free app is great to see how it works and play around with but I recommend buying Guitar Scales & Chord Power, I love it. Here is my first review below, my apologies to the developer:

I can’t tolerate buying an app and then to find Google advertisements constantly running only to distract you from what you want to be doing. I can see free apps having advertisements but I didn’t see anywhere when I purchased this app that it came with ADVERTISEMENTS!

My bad!!! It would probably help if the developer changed the picture so it would be easy to differentiate between the 2 the apps. I am super happy I bought the paid app!

Developer Response ,

Sorry you are having problems. There is NOT a paid version of this app only free. If you purchased Guitar Scales & Chords Power it is a separate app (with NO ads) and you will find it on your device with with a different app icon that says Guitar SCP below it. Guitar Scales & Chords Power has all of the features of Guitar Scales Power (Guitar SP) and many more; so you can delete Guitar Scales Power (Guitar SP) from your device. If you are still having problems please contact support from within the app or email so we can help.

I Love This App,

I have spent countless hours searching the web for scale diagrams with the proper fingering and have printed out hundreds of pages of material. It has seriously taking over my practice time. I found this app today just browsing the App Store and I can’t believe it’s been there this whole time. Have only been using a couple hours and feel guilty that I’m not paying for.

I will be purchasing this app by the end of the day! 😍😍😁

I am just learning guitar and I love this app!!! It is so useful to be able to hear each note and how they can be blended together. I highly rate this app for anyone wanting to learn scales on their guitar.
