iPhone standard calendar
Was forced to change to a chiffon iPhone gggggrrrrrr everything about it was pants including the calendar so with a bit of surfing round this one, simply marvellous, brings to your attention daily what you have in store. Easy to use and call up … thumbs up from me
A great help👍
This has made my daily tasks easier to see and control enabling better time management and planning of family events too.
Recently have problems with the app
I’ve used this calendar app for many years and been extremely happy with it, however, it now doesn’t sync with my partner’s phone. Tried to sort and can’t 😩
Amazing App
Really helps me schedule my life and improve productivity. Also doesn’t let me forget anything!
Great Calendar but poor support
The app itself is really good and easy to use. However, they claim to want ideas and feedback on how to improve the app but don’t actually do anything or make any changes. There are number of ideas on the support pages which have been supported by multiple users, for example the oldest and most supported idea is over 4 years old. This is a real shame and is a big let down for the product.
Calendar Aggregation
Life just became simpler and easier….thank you!
Have tried many ways to have one view of all calendars; so pleased to find this one.
This app just works.
Nothing more needs to be said.
Excellent App
Have been using this app for a number of years, both on iPad and on Windows. It’s my go to calendar app and very versatile. Easy to change appointment colours and themes, as well as copying or moving appointments. It syncs with Google Calendar and easier to use. Have just downloaded the app onto new iPhone 14 and initial premium licence issue was soon resolved by Jeroen at customer support. Highly recommended.
Not Impressed - Do Not use
I have had this calendar for over two years and initially it was ok.
However, it has become continually worse and the developer does not really seem to care any more - hence why he rarely upgrades it.
It has constant synchronisation error messages and will not change or edit the name of a calendar unless you uninstall/reinstall it - which, on Apple means you have to get a password again etc then reset all the previous settings after re-installing. Why?
I emailed the developer who could be bothered and basically asked’ so what’s your problem? and was not remotely interested.
He’s probably moved on to bigger and better things.
The problem with using apps like this as that you are the mercy/apathy of the developer, so to put your life into the app and they can’t be bothered with it after a while, is folly.
I am learning to stay with ‘mainstream’ app like Apple/Google etc who in a way will always be there - not fickle developers like this one.
I would seriously look at other calendar apps as I now have and will remove this app. Not fit for purpose.
Bye
I could be better
Well there is some stuff that I cannot do because I don’t have a account and password Okey Dokey
Best calendar
It keeps me so organise. U can use different colour for different tasks. It perfect
