| 2.8GPAOwavesGood | 3.0GPASparkDayVery good | |
|---|---|---|
| Value for money | BPlus is $12.99 a month or $99.99 a year on the US App Store, so about $8.33 a month if you pay yearly. That's the middle of the pack for a planner. It buys the AI timing advice, your own categories, and no cap on Day Plans or goals. | BPro is $49.99 a year, about $4.17 a month, or $6.99 monthly. That's a little under the middle for planners. What it buys is modest: no ads, 25 leaderboard friends, premium sounds and clock faces, 5 AI roasts a day and AI daily reports. |
| Free plan and trial | BThe clock planner, seasonal goals, the My Moai friends group and Apple Health and Watch support are all free. But Day Plans and goals are capped on the free version, and Owaves doesn't say at how many. | AThe planner, step tracker, journal, habits, reminders and focus timer are all free, with no account to make. You'll see ads, and the leaderboard stops at 3 friends. Most people could stay right here. |
| Features | BA 24-hour clock view, Day Plans that repeat by weekday or season, goals, and Apple Health to compare the plan with what you really did. But your own categories are locked to Plus, and the FAQ says the iPad app has most, not all, of the iPhone's features. | BA 24-hour timeline with alarms, step counts with leaderboards, habit streaks, a journal with voice-to-text in 15 languages, and a Pomodoro timer with 50 music tracks. Lots packed in. But neither the site nor the App Store listing mentions syncing with outside calendars. |
| Ease of use | A4.6 from about 1,800 App Store ratings. The whole day sits on one clock face, so you can see where sleep ends and work starts without reading a list. | BNo App Store rating on record, so a B is our ceiling. There's no account to set up, so you can open it and start planning. The free version does show ads while you do. |
| Platforms and integrations | DiPhone, iPad and Apple Watch only, which is really one operating system. Apple Health and your device's calendars sync in, and that's the lot. There's no Mac or web version, and Android is a waitlist with no release date. | CiPhone and Android phones only. There's no web or desktop version, and the App Store listing is for iPhone, not iPad. The one connection on record is Health Connect. |
| Best for | seeing your whole day on a 24-hour clock | a planner and step counter that teases you |
