# Sine Pro vs foundU

The clearest difference is rating: foundU at 3.0 against Sine Pro's 2.7. foundU also leads on device support (3 vs 1) and iOS requirement (15.1 vs 17.0). Sine Pro's advantage is ratings volume (41 vs 2) and update cadence (every 3 weeks vs every 6 weeks). 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.

foundU holds the better App Store score, 3.0 against 2.7. That said, the two scores are not equally well evidenced: Sine Pro has 41 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 18% of Sine Pro's written reviews are positive against 13% of foundU's, so the app with the better star average is not the one people write more warmly about.

Sine Pro ships an update every 3 weeks, foundU every 6 weeks. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
