Verdict
The clearest difference is ads: GroupCal at none against SimpleCal's shown. SimpleCal's advantage is ratings volume (17K vs 799). On price, rating, review sentiment and update cadence there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. SimpleCal sells 2 in-app purchases, starting at $0.99 per month and GroupCal sells 9 in-app purchases, starting at $14.99 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 — 4.7 for SimpleCal against 4.7 for GroupCal. That said, the two scores are not equally well evidenced: SimpleCal has 17K ratings behind it against 799, so its average is the more settled of the two. Written reviews are what separate them: 85% of SimpleCal's written reviews are positive against 78% of GroupCal's.
Both ship on a similar rhythm, roughly fortnightly. Both last shipped on September 24, 2026.
