# SimpleFit vs SHIM Calendar

The clearest difference is ratings volume: SimpleFit at 49 against SHIM Calendar's 3. SimpleFit also leads on device support (4 vs 2) and iOS requirement (15.6 vs 18.0). SHIM Calendar's advantage is update cadence (weekly vs fortnightly). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. SimpleFit sells 3 in-app purchases, starting at $9.99 per month and SHIM Calendar sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for SimpleFit against 5.0 for SHIM Calendar. That said, the two scores are not equally well evidenced: SimpleFit has 49 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

SimpleFit ships an update fortnightly, SHIM Calendar weekly. The most recent releases landed on November 8, 2026 and November 5, 2026 respectively.
