Verdict

The call

The clearest difference is rating: FlashAir Image Share at 5.0 against Vertical Calendar.'s 4.0. Vertical Calendar.'s advantage is review sentiment (58% vs 16%) and monetization model (free vs paid). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

FlashAir Image Share holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Vertical Calendar. has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 58% of Vertical Calendar.'s written reviews are positive against 16% of FlashAir Image Share'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. Both last shipped on November 1, 2026.
