Verdict

The call

The clearest difference is review sentiment: Rezzize at 100% against Image Size's 71%. Rezzize also leads on iOS requirement (14.0 vs 18.0). Image Size's advantage is ratings volume (30K vs 33) and rating (4.7 vs 4.4). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Image Size holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Image Size has 30K ratings behind it against 33, so its average is the more settled of the two. Written reviews complicate that: 71% of Image Size's written reviews are positive against 100% of Rezzize's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Image Size ships an update fortnightly, Rezzize every 3 weeks. The most recent releases landed on September 25, 2026 and September 17, 2026 respectively.
