A message appears saying wrong email format. Help!. ### 1/5 — Not sure they know what a calendar is! *2020-03-05, version 3.1.3* They call an appointment (entry) a calendar. Fairly useless. ### 1/5 — Terrible!!!  *2011-12-03, version 1.9.0* Absolutely awful in a terrible way! ### 2/5 — No instructions, X’s and O’s are confusing *2024-10-12, version 3.1.3* When I chose 3 steps, the third step is an X which should mean that I completed all three steps. Instead, it’s been logging the activities as incomplete. This is a huge error with this app, I’m surprised that no one else is writing about it. ### 3/5 — Some odd choices, but not bad *2021-01-17, version 3.1.3* It’s a very simple daily schedule app, that works well. But there are a few things that are... odd, to say the least -sometimes when I want to edit a “calendar,” it Bugs out and makes me close and open the app -why do you call it “calendars” when they’re different repeating reminders? -why have the one step and two step be different? They’re both 100% or 0% in the overview. -I WANT DARK MODE. I normally work on this before I go to bed, and I like not being blind. -odd that you skipped “four step,” but ok, I guess? ### 3/5 — A bit confusing *2015-03-08, version 2.1.0* It works for the most part but when I tried to look at the user guide it's in another language. The app icon keeps telling me that I have a message or something but I can't find what they're trying to get me to look at. ### 4/5 — 9/10 - Fix the issue where notes are not saved *2023-10-03, version 3.1.3* Great app, gets the job done. My only complaint is with disappearing notes on individual calendar dates. Sometimes when you type a note of any length for a day, you press "done" to save the note and then nothing is there. *Poof* 5/5 app rating if all calendar notes were saved when written. ### 4/5 — Don’t let the name fool you *2022-02-13, version 3.1.3* This is a good app, but it’s not exactly what you’d expect it to be. If you searched for “calendar” or “schedules” or “task” in the App Store, this will most likely show up. But it’s not really for day to day calendar viewing or task management. But, once understood and applied appropriately, it can serve as a very good tool for a very niche application or group. Rather than a default scheduling calendar like the name implies, I see that it’s best for organizing multiple scheduled tasks (known in app as “calendars”, but they really are not full calendars) that repeat themselves on a weekly basis. For example, workout calendars for each body part or weekly housekeeping tasks by room. It’s a very specific and intricate application if used correctly, but it’s not well explained. ### 4/5 — Perfect! *2020-09-28, version 3.1.3* This is exactly what i've been looking for. Simple. ### 4/5 — Nice *2018-05-24, version 3.1.1* I’m using it everyday! ## Most praised reviews (10 highest-rated) ### 5/5 — Simple, easy and functional *2022-12-30, version 3.1.3* This calendar is so simple and practical. I find it easy to set up and easy to use. ### 5/5 — Simple but brilliant *2022-10-23, version 3.1.3* Simple but brilliant ### 5/5 — Good functionality - if you can figure out how to use it *2019-12-23, version 3.1.3* No clear instructions but the idea is you can have many different tasks you are trying to get yourself into the habit of doing. Some are only on Saturdays, some are every evening, etc. And each task can be done in the best way (like if you did the full workout), a mediocre way (like you only did half the workout) or not at all (you skipped your workout completely that day). So a circle means best, a triangle means so-so and an X means you missed it. ### 5/5 — This app is awesome *2017-12-15, version 3.0.5* Just what I needed title for calendar so I can name my activity and to mark my days off. So I can keep track of how many days of been doing it. You can create as many calendars as you want. It’s easy to use, and you can quickly edit a calendar as you please. Whoever created this app is awesome. Thanks. Makes life a lot easier. Cheers. ### 5/5 — Perfect! *2017-11-29, version 3.0.5* This is exactly what I was looking for. I wanted a calendar to track and check off days during my 12 week fitness prep. To the developers: I found this app with luck after several failed searches along the lines of “mark off days calendar” “custom mark off calendar” etc. I only found this app because I searched “check calendar” (having no idea this app existed so I definitely wasn’t searching the name). If I were you I’d look into optimizing your keywords because it’s a useful app and a shame it doesn’t seem to be getting much exposure. ### 5/5 — Cute and useful *2013-04-18, version 2.1.0* Useful to me. ### 5/5 — Perfect *2013-01-12, version 2.0.0* Beautifully designed, simple app. Hot this to quickly log my workouts, will provably use for grad school too. ### 5/5 — App *2011-10-13, version 1.1* I love this app!! ### 5/5 — Cute *2011-10-07, version 1.1* Cute ### 5/5 — cool *2011-09-28, version 1.0* nice app! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
