# FFT vs FFT Plot

The clearest difference is rating: FFT Plot at 4.8 against FFT's 4.0. FFT Plot also leads on in-app purchases (none vs 1) and ratings volume (90 vs 6). FFT's advantage is update cadence (every 6 months vs every 17 months). On review sentiment, ads and device support there is nothing between them.

FFT costs $10.99 and FFT Plot $9.99 up front. FFT sells 1 one-off in-app purchase. FFT Plot asks for nothing beyond the download.

FFT Plot holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: FFT Plot has 90 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 86% of FFT's written reviews are positive against 84% of FFT Plot's, so the app with the better star average is not the one people write more warmly about.

FFT ships an update every 6 months, FFT Plot every 17 months. The most recent releases landed on September 22, 2026 and September 23, 2026 respectively.
