# Trout vs Thortspace

The clearest difference is rating: Trout at 4.8 against Thortspace's 3.5. Thortspace's advantage is update cadence (weekly vs every 5 months) and iOS requirement (13.0 vs 18.6). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Trout sells 3 in-app purchases, starting at $2.49 per 2 months and Thortspace sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Trout holds the better App Store score, 4.8 against 3.5. Both are backed by a comparable volume of ratings — 4 and 4 respectively. Written reviews complicate that: 33% of Trout's written reviews are positive against 40% of Thortspace's, so the app with the better star average is not the one people write more warmly about.

Trout ships an update every 5 months, Thortspace weekly. The most recent releases landed on September 22, 2026 and September 15, 2026 respectively.
