Hey there! I've been using Chordana Play for a while now, and I totally acquire where you're coming from. One thing that really helped me was customizing the app settings to slow down the tempo at first. This way, you can focus on getting the notes right before speeding up. Also, try using the loop function on tricky sections to practice them repeatedly.
As for daily practice, I usually dedicate a specific time each day just for working with the app. It helps in building a routine and gradually improves your skills. Don't forget to take advantage of the MIDI connection feature if you have an electronic keyboard—it makes learning much more dynamic!
Overall, just keep experimenting with different features until you find what works best for your learning style. Hang in there, and enjoy making music!
