# PWND vs Sci

The clearest difference is rating: PWND at 5.0 against Sci's 3.9. PWND also leads on monetization model (ad-supported vs free with in-app purchases) and iOS requirement (9.3 vs 18). Sci's advantage is review sentiment (56% vs 40%) and ratings volume (14 vs 4). On price, update cadence, 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.

PWND holds the better App Store score, 5.0 against 3.9. Both are backed by a comparable volume of ratings — 4 and 14 respectively. Written reviews complicate that: 40% of PWND's written reviews are positive against 56% of Sci's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 4 months. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
