# Simplicity Connect vs Dabble

Simplicity Connect and Dabble both sit at 4.1 stars, but that hides the real split: 75% of Dabble's written reviews are positive against 50% of Simplicity Connect's. Dabble also leads on ratings volume (128 vs 16) and iOS requirement (11.0 vs 17). Simplicity Connect's advantage is update cadence (every 2 months vs every 6 months). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Simplicity Connect holds the better App Store score, 4.1 against 3.9. That said, the two scores are not equally well evidenced: Dabble has 128 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 50% of Simplicity Connect's written reviews are positive against 75% of Dabble's, so the app with the better star average is not the one people write more warmly about.

Simplicity Connect ships an update every 2 months, Dabble every 6 months. The most recent releases landed on August 2, 2026 and September 23, 2026 respectively.
