Answer · Practice Lab

Is there an app that tells me if I am rushing or dragging when I play?

Practice Lab listens to your playing through the iPhone microphone and reports tempo consistency and rhythm accuracy, which is where rushing and dragging show up. A plain metronome only tells you what the beat is, not whether you stayed with it.
