|---|---|---|
| Value for money | APRO is $19.99 a year or $3.99 a month on the US App Store, well under what paid calendar apps usually charge. One subscription covers Mac, iPhone, iPad and Apple Watch. Readdle also announced a Lifetime option at $59.99. | BThe paid version only comes inside Google Workspace, from $7 a user a month on a 1-year commitment. That's about typical, and Gmail, Drive and Meet come with it. But Starter adds nothing to the calendar itself. More booking pages and payments wait for Standard at $14. |
| Free plan and trial | BThere's a free plan, but it's a basic calendar with one alert per event. Tasks, more than one account, recurring events and plain-language input are all PRO. The 7-day PRO trial charges you when it ends unless you cancel. | AFree with a personal Google Account on web, Android and iPhone, with one appointment booking page thrown in. Most people will never pay. Extra booking pages, payments and automatic email reminders are the paid bits. |
| Features | AGoogle, iCloud, Outlook and Exchange in one view, tasks from Apple Reminders or Google Tasks beside your events, and typing like "Coffee with Alex next Tuesday at 9 am". PRO also books Google Workspace meeting rooms, and there's a habit tracker. | AShared, colour-coded calendars you can view together, a booking page, Google Meet links and files on events, and Google Tasks next to them. Workspace plans add Gemini scheduling from Gmail and Time Insights, though Time Insights only shows on a computer. |
| Ease of use | A4.7 from about 122,000 App Store ratings. Type an event in plain words and it fills in the date and time, then move things around by drag and drop. | B4.5 from about 132,000 App Store ratings. If you have a Google Account there's nothing to set up. On Workspace plans, an event spotted in an email can be added with one click. |
| Platforms and integrations | CiPhone, iPad, Mac, Apple Watch and Apple Vision, and it connects Google, Outlook and Exchange accounts. But the apps are all Apple. No Windows, Android or web version is listed. | AWeb, Android and iPhone, tied into Gmail, Google Meet, Google Tasks and Stripe for paid bookings. No desktop app is listed, so on a computer it lives in a browser tab. |
