jonmach Posted April 1 Posted April 1 All,  I recently created a few iOS (not Android ) apps for my own use that filled a gap in terms of my having quick access to the tools that I want to use with my own guitar journey. I liked them so much, that I decided to put them on the Apple App Store:  Guitar Toolkit https://apps.apple.com/gb/app/gtk-guitar-toolkit/id6749509640 A set of tools that I find useful, and still use today: Tuner Metronome Scales - around 100 different scale types together with a visualisation of these on a fretboard Circle of Fifths - interactive CoF tool allowing you to choose your root, and determine your diatonically related chords Position finder - Want to play in a specific key, but in a place on the fretboard that suits you? Want to play without having to slide your hand up and down the fretboard? Use this Mode converter - convert from one musical mode to another in any key Note practice - use this to help you practice and become intimate with where every note is across the entire fretboard. Hear the note as it sounds on your guitar and choose a speed that suits you Triad practice - some idea as note practice. Pick your string sets, inversions and chords. Practice at a speed and range of chords that suits you. Chord master - work out how to play a specific chord, or find the name of a combination of strings/frets Chord Transposer - take an existing set of chords for a song, and just pick a new key to play it in. It will transpose every chord. A comprehensive song book app:  https://apps.apple.com/gb/app/gtk-songbook/id6759207277  Imports ChordPro songs from cloud storage Transpose your songs into different keys.
