Verdict
The clearest difference is price: Calendars at Free against Do! Premium's $20.00. Calendars also leads on ratings volume (123K vs 238) and chart position (#150 vs unranked). Do! Premium's advantage is review sentiment (75% vs 56%) and iOS requirement (15.0 vs 18.2). On rating, ads, in-app purchases and monetization model 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
Calendars is free to download; Do! Premium costs $20.00 up front. Do! Premium sells 1 one-off in-app purchase and Calendars sells 18 in-app purchases, starting at $3.99 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 Do! Premium against 4.7 for Calendars. That said, the two scores are not equally well evidenced: Calendars has 123K ratings behind it against 238, so its average is the more settled of the two. Written reviews are what separate them: 75% of Do! Premium's written reviews are positive against 56% of Calendars's.
Do! Premium ships an update fortnightly, Calendars weekly. Both last shipped on November 1, 2026.
