# PrismScope vs Flasia HD

The clearest difference is update cadence: Flasia HD at every 5 months against PrismScope's every 15 months. Flasia HD also leads on review sentiment (100% vs 90%). PrismScope's advantage is price ($1.99 vs $3.99) and iOS requirement (9.1 vs 15.6). On rating, ratings volume, ads and in-app purchases there is nothing between them.

PrismScope holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 5 and 11 respectively. Written reviews complicate that: 90% of PrismScope's written reviews are positive against 100% of Flasia HD's, so the app with the better star average is not the one people write more warmly about.
