Verdict
The clearest difference is rating: Shutter at 4.8 against Convertizo's 4.2. Shutter also leads on update cadence (daily vs every 8 days) and price ($0.99 vs $3.99). Convertizo's advantage is review sentiment (66% vs 50%) and ratings volume (75 vs 5). On ads and in-app purchases there is nothing between them.

Shutter holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Convertizo has 75 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 66% of Convertizo's written reviews are positive against 50% of Shutter's, so the app with the better star average is not the one people write more warmly about.
Convertizo ships an update every 8 days, Shutter daily. The most recent releases landed on September 21, 2026 and September 8, 2026 respectively.
