Hi @sequences
The clue is in your username Michael.
The vast majority of songs have several chords that come in very predictable patterns that repeat over and over.
Write them down to see this and you will much more quickly recognise when to change (by reading) which will then help train your ear to know when to change (by listening).
In my opinion, not being an app user, and not knocking its worth at all, one of the issues the song app can create is that beginners do not get any sense of song structure as chords come one at a time in a linear manner. Whereas songs are built on chord progressions that belong together in groups.
Look at these two different representations of the chord progression for the exact same song. It is not a simple chord progression compared to some, though it does have its patterns and repeated sections. One representation is linear, one is structured and arranged. Which is best to learn and memorise is fairly obvious to my eye.
A linear arrangement of chords:
A structured arrangement in a ‘chord chart’:
Hope that helps.
