ReceptionRating · Positive reviews · Number of ratings

Osmo Projector holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: Linea Sketch has 802 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 62% of Linea Sketch's written reviews are positive against 33% of Osmo Projector's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Linea Sketch ships an update every 3 months, Osmo Projector every 2 months. The most recent releases landed on October 22, 2026 and October 21, 2026 respectively.
