# Tiff Viewer vs PIX4Dcatch

The clearest difference is update cadence: PIX4Dcatch at every 2 weeks against Tiff Viewer's every 4 months. PIX4Dcatch also leads on rating (4.7 vs 4.5). Tiff Viewer's advantage is iOS requirement (11.0 vs 18.0). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Tiff Viewer sells 2 one-off in-app purchases and PIX4Dcatch sells 1 in-app purchase, starting at $159.00 per month. Whichever you choose, the download price is not the number that matters.

PIX4Dcatch holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 212 and 264 respectively. Written reviews complicate that: 36% of Tiff Viewer's written reviews are positive against 33% of PIX4Dcatch's, so the app with the better star average is not the one people write more warmly about.

Tiff Viewer ships an update every 4 months, PIX4Dcatch every 2 weeks. The most recent releases landed on October 22, 2026 and October 20, 2026 respectively.
