# HydraLakes vs TIFF Viewer

The clearest difference is review sentiment: TIFF Viewer at 100% against HydraLakes's 33%. HydraLakes's advantage is rating (5.0 vs 4.0) and iOS requirement (15.0 vs 17.0). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. HydraLakes sells 14 one-off in-app purchases and TIFF Viewer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

HydraLakes holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 2 and 1 respectively. Written reviews complicate that: 33% of HydraLakes's written reviews are positive against 100% of TIFF Viewer's, so the app with the better star average is not the one people write more warmly about.

HydraLakes ships an update fortnightly, TIFF Viewer every 10 days. The most recent releases landed on September 13, 2026 and July 20, 2026 respectively.
