Verdict
The clearest difference is ratings volume: Calendars at 122K against GroupCal's 799. Calendars also leads on chart position (#104 vs unranked). GroupCal's advantage is review sentiment (78% vs 55%) and iOS requirement (16.0 vs 18.2). On price, rating, update cadence and ads 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. Calendars sells 17 in-app purchases, starting at $3.99 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 Calendars against 4.7 for GroupCal. That said, the two scores are not equally well evidenced: Calendars has 122K ratings behind it against 799, so its average is the more settled of the two. Written reviews are what separate them: 55% of Calendars's written reviews are positive against 78% of GroupCal's.
Calendars ships an update every 11 days, GroupCal fortnightly. Both last shipped on September 24, 2026.
