Verdict
The clearest difference is review sentiment: Luban Calculator at 100% against Shutter's 50%. Luban Calculator also leads on price (Free vs $0.99). Shutter's advantage is rating (4.8 vs 4.0) and in-app purchases (none vs 1). On ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Luban Calculator is free to download; Shutter costs $0.99 up front. Luban Calculator sells 1 in-app purchase, starting at $0.99 per month. Shutter asks for nothing beyond the download.
Shutter holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Shutter has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Shutter's written reviews are positive against 100% of Luban Calculator's, so the app with the better star average is not the one people write more warmly about.
Shutter ships an update daily, Luban Calculator monthly. The most recent releases landed on September 8, 2026 and September 14, 2026 respectively.
