FROM QUICK MARKUP TO A FINISHED REPORT Start with one arrow. Add measurements, callouts, and notes as the job grows. When the photo set is complete, export every annotated image into a single PDF with your own template, or share the editable project file so a colleague can pick up where you stopped. BUILT FOR REAL WORK Annotium helps contractors, inspectors, technicians, teachers, students, designers, support teams, and anyone who needs to explain something visually.

Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.
