Ultimate Ear Trainer

★★★★★ All switches (options) are on the same screen - so, simple to use. Has a good quality instrument sound (piano). Only trains in C major - which is all that is needed (for major keys) when using a functional (contextual) ear trainer, i.e. the relationships between scale degrees in major keys remain the same, though of course the pitches differ. One problem I experienced, is that if you turn CHORDS on and later turn it off, you can't return to 1 "test" note in the NOTE GROUP. (This shows the number of notes heard in a "test".) The only way I can get around this is to uninstall the app and reinstall it - then refrain from turning CHORDS on again. There seems to be is a slider with "NOTE GROUP" but it didn't move, i.e. didn't alter the number of notes in the NOTE GROUP. Finally, the font size used in the app for HELP and for the switches is very tiny. I had to use a magnifying glass, though I soon remembered what each switch did. Anyway, you are unlikely to need to use the switches frequently. You are likely to start with only PLAY CADENCE switched on - and you are likely to be in that mode for a long time.
