# TB Spectrogram vs Warp

The clearest difference is monetization model: Warp at free against TB Spectrogram's paid. Warp also leads on rating (4.9 vs 4.4) and iOS requirement (11.0 vs 13.0). TB Spectrogram's advantage is ratings volume (50 vs 11). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Warp holds the better App Store score, 4.9 against 4.4. Both are backed by a comparable volume of ratings — 50 and 11 respectively. Written reviews complicate that: 71% of TB Spectrogram's written reviews are positive against 67% of Warp's, so the app with the better star average is not the one people write more warmly about.
