Twice it abruptly crashed. I uninstalled, cleared my iPhone cache as I was rebooting my phone, then reinstalled. The fact that it is taking over three hours to sync a simple calendar without thousands of events shows that this app needs a tremendous amount of work to be considered functional and to have good UX. On this one folks, you should pass. Great concept, just not ready for market. This could explain whether there are so few users and reviewers. ### 3/5 — lagging and shutting off, but interesting concept. *2024-10-05* the settings can not be closed appropriately – you have to close the app and reopen it. + the U-bar can really load (stress) the fone's processor, which creates huge lags. though the concept itself is cool + switching from minutes - days - month to years feels great. i would like to try fixed version of it, but... i see no perspectives, as the last update of the app was made 2 years ago (in 2022). ### 3/5 — Useful visual, but too slow *2023-01-14* I love how the day view shows my appointments, how the week view shows special days, and how the month view shows trips. I’ve wanted this for a while. Unfortunately, scrolling is really sluggish, and sync is slow and inscrutable enough that I can’t trust that it’s ever showing everything. ### 3/5 — Sync problems *2022-07-12* Great concept, great design — sadly, the changes to your schedule you make in your iPhone calendar are not always reflected in the app ### 4/5 — Great app! *2023-03-16* I love this, i love that i can traverse through my life’s schedule with ease, not being clouded by too many numbers and being able to see all my events and to-do’s. my only critique is that i think when you turn your phone sideways you should be able to scroll horizontally. otherwise this app works wonders in my life! ### 4/5 — Googleカレンダーとの同期 *2023-01-16* Googleカレンダーとの同期ができたら、とても素晴らしい ### 4/5 — Snappy until you change a setting or event *2022-10-17* On initial use, the actions are smooth and satisfying. However, the first thing I tried to do was turn week numbers on (it’s the only setting available before you import calendars) and it did freeze up on me—I force closed and the app was smooth again. I imported my calendars next, and it went well, but clicking “edit event” to preview it then clicking “Cancel” yet again slowed the app to a crawl. Overall, I really love the app, though, and I hope the developer plans on making a few stability improvements. I’d also appreciate the ability to drag events, but I can live without it. Maybe a widget or two? 😁 The app has a ton of potential benefits, but most significant is that it’s the only app I’ve ever seen that allows overnight workers to view a single shift as a single block. Life isn’t confined to paper calendar pages. I’m gleeful this exists, I really am. ### 5/5 — Brillant! *2025-08-28* Please, make it available macOS and iPadOS.🙌 ### 5/5 — 便利で分かりやすい *2025-04-14* 便利でわかりやすい。 iCloud以外のGMailのカレンダーも、追加される。 追加されない場合、設定アプリから、メールアカウントを追加するとiOSのカレンダーアプリやこのアプリでも表示できる。 ## Most praised reviews (2 highest-rated) ### 5/5 — 很好的应用 *2025-01-27* 能否添加中文支持 Can you add Chinese support? ### 5/5 — how to use it？ *2024-08-18* what is this app for？ --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
