# DoodleConnect vs Circle & Sphere

The clearest difference is review sentiment: Circle & Sphere at 100% against DoodleConnect's 56%. Circle & Sphere also leads on update cadence (every 3 weeks vs every 2 months). DoodleConnect's advantage is rating (4.7 vs 4.0) and in-app purchases (none vs 8). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Circle & Sphere sells 8 one-off in-app purchases. DoodleConnect asks for nothing beyond the download.

DoodleConnect holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: DoodleConnect has 56 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 56% of DoodleConnect's written reviews are positive against 100% of Circle & Sphere's, so the app with the better star average is not the one people write more warmly about.

DoodleConnect ships an update every 2 months, Circle & Sphere every 3 weeks. The most recent releases landed on September 21, 2026 and September 19, 2026 respectively.
