Free online ukulele metronome
A metronome clicks a steady beat so you can hear if you play too fast or too slow. Set the BPM, pick a time signature, and match your strum to the click. The first beat of each bar is louder so you can feel where the bar starts.
Start around 60 to 80 BPM. Practice two chords until the change is clean, then add more chords or a full song. Raise the tempo by about 5 BPM only when you can play the pattern three times without mistakes. Use a chord progression when you want to train real song changes.
