We’ve chosen to include these incomplete lenses in the app because of Panavision's importance in the industry.

The call

The clearest difference is rating: LensKit at 4.9 against Storyblocker's 4.4. LensKit also leads on ratings volume (56 vs 7). Storyblocker's advantage is review sentiment (100% vs 75%). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

LensKit holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: LensKit has 56 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 75% of LensKit's written reviews are positive against 100% of Storyblocker's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
