# Annot8 vs Annotium

The clearest difference is review sentiment: Annot8 at 91% against Annotium's 44%. Annot8 also leads on iOS requirement (9.0 vs 15.6). Annotium's advantage is rating (4.0 vs 3.5) and update cadence (daily vs every 2 weeks). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Annot8 sells 1 one-off in-app purchase and Annotium sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Annotium holds the better App Store score, 4.0 against 3.5. Both are backed by a comparable volume of ratings — 11 and 4 respectively. Written reviews complicate that: 91% of Annot8's written reviews are positive against 44% of Annotium's, so the app with the better star average is not the one people write more warmly about.

Annot8 ships an update every 2 weeks, Annotium daily. Both last shipped on October 24, 2026.
