1. You are likely to start with only PLAY CADENCE switched on - and you are likely to be in that mode for a long time.This app is like the Functional Ear Trainer (which is also available for Android): it plays I IV V I cadence and then plays a note (either from the major scale or the chromatic scale) and asks you to identify the note.
2. 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.
3. But I would recommend trying the Functional Ear Trainer over this app if you're looking to get started.great app! what's great about this app in contrast with the Functional Ear Trainer is that this one allows you to guess multiple simultaneous tones.. 3 simultaneous random tones is already challenging.. it allows up to 8.
4. By default it starts out with 'Full Extension' and 'Chromatic' options enabled, which means that you have to identify a note from the piano keyboard from three octaves, which is pretty challenging.
5. 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.
6. Unlike the FET, it also allows you to play multiple notes harmonically after the cadence, so you can play up to 8 (!) notes simultaneously after the cadence, which is very challenging.
7. 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.
8. It requires that you answer using a piano keyboard (instead of using scale degrees like the FET).
9. (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.
10. The piano sounds are nice as well, and the app visually looks good.
11. Finally, the font size used in the app for HELP and for the switches is very tiny.
