# FFT vs Guitar Tap

The clearest difference is rating: Guitar Tap at 5.0 against FFT's 4.0. Guitar Tap also leads on in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 6 months). FFT's advantage is price ($10.99 vs $14.99) and ratings volume (6 vs 1). On ads and device support there is nothing between them.

FFT costs $10.99 and Guitar Tap $14.99 up front. FFT sells 1 one-off in-app purchase. Guitar Tap asks for nothing beyond the download.

Guitar Tap holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: FFT has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 86% of FFT's written reviews are positive against 100% of Guitar Tap's.

FFT ships an update every 6 months, Guitar Tap every 3 weeks. Both last shipped on October 18, 2026.
