A few tips before you play
Allow the microphone. The first time you tap Record, your phone will ask to use the mic — please tap Allow (that's the whole point). Nothing is recorded until you tap Record, and it stops the moment you tap Stop.
Don't hunt for a quiet room. Your normal home sounds — a fan, people talking, traffic outside — are exactly what we want.
Use an acoustic guitar (not electric), and give it a quick tune first if you can.
Rest your phone somewhere natural — a table or sofa about 1–2 m (3–6 ft) away. Don't prop it right against the guitar.
Play the loop 6–8 times through — a minute or two is plenty.
Strum however feels natural — any pattern is fine, and it's good to use a different one on different takes; just let the chords ring.
Any mistake is fine — just keep going. Real mistakes are useful data, not a problem.
Thanks — here's the plan 🎸
Work down the list: tap Record, play the chords a few times through (about a minute), tap Stop. That's one done — go to the next. Aim for the six below; the bonus rounds are extra if you're enjoying it.

A steady, comfortable pace is perfect — around 80 beats a minute is ideal (a metronome helps if you have one). For the song, just play it at a natural pace.

Bonus rounds — only if you're up for it
Same progressions with a richer chord — a 7th or a suspended (sus) chord. These teach the tool more; skip any you don't know the shapes for. Totally optional.
