Online family organiser/ diary app recommendations

[summerdaysgain]

I am looking for recommendations for a family organiser/ diary app (which can be used on 1. phone and 2. ipad and/or computer). I think my meticulously organised but technologically limited paper diary has just about had its day. I want an app where family members even friends can see some (maybe not all) of your calendar and can be used for shopping lists, repeat appointments, alarms etc. A colleague suggested Cozi.

Does anyone have a favourite for this - it is rather like looking at trip advisor - I just think I have found a good one and then I find 5 reviews that say the app is a total waste of time and am back to square 1. In terms of a must have I really want different family member events/appointments to appear in different colour fonts so I know where to collect the right child from and ideally somewhere to put long term reminders in. Anyone have an app like this anything they cannot be without? Thanks.

Google calendar - its basic, but you can have multiple different calenders with different sharing settings linked to one/many accounts. Plus you can have things on repeat.

Cozi! It's really simple to use and you can clearly see who's where and when.
