I cant enable the weather ( its all correct in the Setting) Any idea? ### 4/5 — Appearance on iPhone 11 Pro *2019-11-03, version 3.3.5* Great app and have been using it for years on my different iPhones however the border seem to look out of alignment on iPhone pro. Please fix. ### 3/5 — Does it still work? *2019-06-28, version 3.3.5* I have no possibility to add Dates or to import my calendar dates. I would love to use this app and would be thankful for hel ### 3/5 — Sadly Another *2018-07-26, version 3.3.5* It looks like another promising app has gone into no more updates land. If you have an older phone and are finding your apps slowly becoming unusable, this app might be for you. However, it looks as if this is not going to be updated anytime soon as the link to its homepage no longer works, comments speak of not being able to contact the developer, and there are bugs in ios 11+. It looked like a good idea. Sad that I won’t be able to give it an honest try. I give it 3 stars as it looks as if it was pretty decent at one time and to applaud the developer for venturing into what appears to be a field that is becoming tougher and tougher to break into and to continue to survive. It appears to be the cycle. New technology (personal computers, operating systems, the internet, cell phones, smartphones)...at first everyone and their cousin can break in to make a contribution and some money....but in the end, only the big ones (usually owned or eventually owned by the same people) survive. Just to clarify, I said it appears that the developer is not going to update anymore. It’s still in the app store, so maybe the developer will look at this post, see that there are those that see the app as promising, and be encouraged to give it one more try. Maybe it could happen? ### 4/5 — Love this app! *2017-11-01, version 3.3.5* I love this app and use it often! Great to have!! Recently however I’m having issues syncing my google calendar. I can still see other people’s calendars though. ### 3/5 — A good option to Fantastical *2017-06-04, version 3.3.5* Looks like a great app with calendars and reminders combined in a beautiful interface. Needs the Search function and the ability to enter events or reminders with natural language input. Once done it good fight with Fantastical or Calendar 5 or Google Calendar for numero uno position ### 2/5 — Weather doesn't work (Australia) *2017-03-24, version 3.3.5* Hi ! I like the idea of ur app but the weather just doesn't seem to be displaying properly ? It keeps asking me to turn on location for weather but my weather is working fine and location has been turned on I am so confused . iPhone 6s ### 2/5 — Looks nice but limited *2016-11-21, version 3.3.5* Looks nice but limited control over how it looks and it failed to pull my iOS calendar and reminders in correctly. Has the potential to be something good if the bugs are ironed out. ### 2/5 — Unable to add calendars *2016-10-22, version 3.3.3* Started with flashing screen of Location request. Once resolving this issue was unable to add calendars. Seemed like a nice app had I been able to do this. ### 4/5 — Very good *2016-10-05, version 3.3.3* What I miss most are some funny stickers to mark my tasks, and the rest is fine. ### 3/5 — Good but improvement needed *2016-06-05, version 3.3.3* The app is functional and does the basic, but the reminder notifications do not work or unclear to set up and it doesn't properly sync reminders and events. Also, the app loses badge notifications on and off. Clearly there are bugs that need to be fixed. ### 4/5 — Really good, just need some improvement *2015-10-26, version 3.3.3* I really like the simplicity of this app. I would like it to automatically open to the current date. ### 4/5 — Great app *2015-10-14, version 3.3.3* It's clean, easy to see. It syncs great with my other calendars. It would be nice if it offers more themes and the date in the icon badge will update without opening the app. Best you can get for free. ### 3/5 — Needs some improvement *2015-09-22, version 3.3.3* Some of the lists and calendars not working correctly. Doesn't appear to have any app manual or support to figure things out. Has a lot of potential, but needs a bit more help first. ### 4/5 — Simple and sleek but needs bug fixing *2015-06-29, version 3.3.3* I really like how simple to use it is. It's easy to see your schedule in day/week/month view and the interface is really nice but there are some annoying bugs that need fixing! For example sometimes tasks go missing when you try to add them and then cannot be deleted despite adding to the total task count. Also whenever I select week view it defaults to showing me the next week rather than the current one which is annoying. Would have been 5 stars if it weren't for these bugs. ### 2/5 — Some options/lists will not open *2015-06-14, version 3.3.3* Some things are syncing and some are not, and I can't choose a default calendar, or what calendars to display. When the list is open, it is blank. This looked like it was going to be a good one. ## Most critical reviews (10 lowest-rated) ### 1/5 — No longer works with new update *2020-12-07, version 3.3.5* Please help ### 1/5 — No app support *2017-06-27, version 3.3.5* I cannot contact app support. The page the link directs to is invalid. The app seems awesome, but I can't get the weather to work. Location services are turned on for the app, but nothing. ### 1/5 — Đm *2016-11-11, version 3.3.5* đm như cái bùi lồn vô cứ văng ra ### 1/5 — Absolutely abysmal! *2016-09-21, version 3.3.3* This app looks great. However, it kept asking me for my location over and over on repeat, not matter how quickly or how many times I tapped, it just didn't stop/go away. Of course I couldn't close the app or shut down my phone the normal way, because of the repeat asking. I had to manually force reset my phone. Don't download this app until it gets an update where they fix this. ### 1/5 — Will Not Open *2015-04-16, version 3.3.3* iPhone 4 with iOS 7, app will not open ??? ### 1/5 — Needs help. *2014-08-28, version 3.1.2* I was hoping for a much more visual interface (aka Kaleidascope?) & more control when organizing tasks, events, project deadlines etc. Fell flat. Needs some major design overhauling. ### 1/5 — Major set back *2014-07-19, version 3.1.1* No push notification ! ### 1/5 — Almost nice *2014-02-10, version 2.0.4* It can not sync with google calendar which I quite disappointed. ### 1/5 — Wish it worked... *2013-11-10, version 2.0.3* This app has a really nice interface with plenty of features... Unfortunately after 15 mins of use it became impossible to update or edit entries... It would crash as soon as I attempted to update... So I'm giving up on this one ### 1/5 — App closed automatically *2013-10-15, version 2.0.2* App pop back to main page whenever I try to set an alarm within an event. Please fix it ASAP as it was a great app back then. ## Most praised reviews (10 highest-rated) ### 5/5 — Best calendar app for me *2020-07-23, version 3.3.5* This is by far the best calendar app for me. There are few calendar apps that does a weekly view the way this does. I hope the developer continues to update the app to better fit newer models. ### 5/5 — Works great with omnifocus *2017-08-24, version 3.3.5* I was trying to find a calendar app that worked well with omnifocus and I came across this hidden gem. Omnifocus iPhone app is great but doesn't have a calendar. With Caleido I can look at my day like a planner. The day, week or month. It's very straight forward and it's free. Surprised very few reviews. A+ to the developer. @planner babe, download WeatherBe app, add it as one of calendars. Weather will be displayed. ### 5/5 — Awesome e-calendar! *2016-06-28, version 3.3.3* This app is pretty amazing, easy to manage, and extremely helpful!! ### 5/5 — Prima *2016-05-27, version 3.3.3* Sehr übersichtlich 👍 ### 5/5 — Easy to use! *2015-11-30, version 3.3.3* One of the better calendars I use in iPhone. ### 5/5 — Perfect Calendar For Students!! *2015-10-27, version 3.3.3* I love this calendar on iOS. It's so colorful and functional. It combines calendar with reminders and weather!! It has tons of free themes. It has so many ways to view your calendar. It even has a week view like the kind you would find in a paper planer. This app is truly a hidden gem. I hope it continues to be supported! ### 5/5 — Very Elegant! *2015-10-17, version 3.3.3* This is a great looking calendar, very sleek and easy to use. It hasn't given me any problems yet and so far it's bug free. It would be nice to see more darker themes. Can't wait for the next update. ### 5/5 — Awesome *2015-06-25, version 3.3.3* Love it ### 5/5 — Great App! *2015-06-03, version 3.3.3* I love the different options to view calendar events (e.g., day, week, etc.). This app is very easy to use! ### 5/5 — Great App *2015-05-31, version 3.3.3* FINALLY I FOUND THIS! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
