# Jasuto vs Shaper

The clearest difference is update cadence: Jasuto at every 3 months against Shaper's every 24 months. Jasuto also leads on price ($4.99 vs $9.99) and review sentiment (80% vs 64%). Shaper's advantage is rating (4.4 vs 4.1). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.

Jasuto costs $4.99 and Shaper $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Shaper holds the better App Store score, 4.4 against 4.1. Both are backed by a comparable volume of ratings — 38 and 18 respectively. Written reviews complicate that: 80% of Jasuto's written reviews are positive against 64% of Shaper's, so the app with the better star average is not the one people write more warmly about.

Jasuto ships an update every 3 months, Shaper every 24 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
