### 3/5 — Great App, but

*2024-09-07, version 3.3.5*

The Problem is the weather widget. I cant enable the weather ( its all correct in the Setting) Any idea?

### 1/5 — No longer works with new update

*2020-12-07, version 3.3.5*

Please help

### 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.

### 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.

### 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.

### 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.

### 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
