The calendar is shared. Everyone said yes to the invite. And the electricity bill still went out on the first while the account was empty, because the bill was never on the calendar.

Nobody put it there. Nobody ever does.

That is the bit the search for the best shared calendar app usually misses. Almost every page ranking for it is written by a calendar app ranking itself first, and they compare the same things: colour coding, widgets, how many views. For a household the question that decides it is simpler and harder. What gets onto the calendar without somebody typing it?

The best shared calendar app is the one nobody types into

A shared calendar holds two kinds of thing. There are events, which have a time and a place: the dentist, football, the parents’ evening. Somebody books them, so somebody is already holding a phone, and getting them onto a shared calendar is easy in any app on this page.

Then there are dates. The car insurance renews on the 14th. The water bill comes out on the first. Your sister’s birthday is Thursday. Nobody books these, they just arrive, and in every calendar app the only way they get on is that one person remembers, opens the app and types them in as an all-day event.

Appointments get onto a shared calendar because somebody booked them. Bills and birthdays get on because somebody remembered, and that person gets tired.

That is the failure we went through in the family calendar nobody uses: one contributor, five weeks, then quiet. The diagram above is the same point across five apps. The top row is identical everywhere. The rows underneath are where they differ.

What a shared calendar looks like when it fills itself

Here is the same household in Chirpy. You add the water bill once in Money, with its amount and the first of the month. From then on it is on the household calendar every month, in Money’s colour, on your phone and your partner’s, and nobody typed a calendar event. The passport you saved in the Vault shows up on the day it expires. Grandma’s birthday, saved once in Family, comes round every year on its own.

Appointments you still add yourself, the same as anywhere: a title, a time, every week until December if it repeats, with a reminder on it. The difference is that the appointment is one row of five instead of the only row anybody keeps.

Chirpy Basic is free for the whole household, up to six people, with no card and no ads. Everyone you invite is on the calendar the moment they join. There is no permission level to choose.

The four other apps worth installing, checked today

Every price and feature below came off the company’s own site or its own support pages on 4 October 2026, not from a rival’s list.

Google Calendar, if everyone already lives in Gmail

Free, fast and on every phone. When you set up a family group on Google, a calendar called Family is created automatically, and everyone in the family sees it in Google Calendar wherever they are signed in. Sharing a calendar with anyone outside that group means choosing one of five permission levels, from “See only free/busy” to “Make changes and manage sharing”. Our guide to share calendar with partner walks through which one to pick.

One thing Google does that we do not yet: if your week is run by work meetings in Google, its family calendar sits right beside them, and Chirpy does not import a Google calendar today. What Chirpy does instead is the half of the week Google never sees, the bill, the renewal and the birthday arriving on the shared calendar without anyone typing them.

Apple Calendar, if every single phone in the house is an iPhone

Family Sharing adds a shared calendar called Family to everyone’s Calendar app, free. It is lovely until somebody is on Android. Apple’s own iCloud help page says that when you share a calendar privately, invitees must have an Apple Account and use iCloud. Anyone else gets a public link they can view and not edit. If one teenager, one grandparent or one partner carries the other kind of phone, this is the wrong calendar.

TimeTree, if the calendar is the whole job

A properly shared calendar on any phone, with a comment thread under each event, free with ads. Premium is $4.49 a month or $44.99 a year, first month free, and its own page says pricing may vary by region. It buys no ads, file attachments, a vertical three-day view and event priority. It is still a calendar only, which is the argument in our TimeTree alternative family calendar comparison.

Cozi, if you want lists next to the calendar and do not mind ads

Cozi Free has a shared calendar, shared grocery and to-do lists, and recipes, with ads, limited reminders and no month view on mobile. Gold is $39 a year and adds month view, calendar search, up to three reminders per event and a birthday tracker. Max is $79 a year and adds AI that turns emails into calendar events. One purchase covers the whole family.

Cozi is the closest to us on this page. The birthday row in the diagram is a paid row there and a free one in Chirpy, and bills and renewals do not reach Cozi’s calendar at all, because there is nowhere in Cozi to keep them.

Best shared calendar app prices: free against free

Free tier against free tier, top tier against top tier, every rival price from its own site on 4 October 2026.

Cozi Gold’s $39 buys a cleaner calendar with birthdays on it. Chirpy Basic costs nothing and buys the calendar with birthdays, bills, renewals and planned dinners already on it, plus the lists, the budget and the documents those dates come from.

Pick by who the calendar is shared with

Most of the ranking pages compare features. The feature grid barely matters. Who is in the house decides it.

• Two adults, both on Gmail, sharing appointments. Google’s Family calendar. Free, and done tonight.
• Everyone on an iPhone, and always will be. Apple’s Family calendar through Family Sharing.
• Two households sharing children. A different problem with its own rules, covered in our guide to the co parenting calendar app.
• A family whose calendar keeps missing the dates that cost money. Chirpy, where the bills and renewals arrive on the shared calendar from where you already keep them.

Setting up a shared calendar that survives November

1. Do not share your personal calendar. Make one for the house. Your work lunches are not your partner’s business, and sharing the whole thing is why people quietly stop adding to it.
2. Put four weeks in, together, on one evening. The repeating things first: football, swimming, the bin day.
3. Put the dates in where they live. In Chirpy that means the bills in Money and the birthdays in Family, once, so the calendar picks them up every month and every year. Our guide to the bill due date calendar has the list of bills worth adding first.
4. Agree who adds what. Whoever books it, adds it. That is the whole rule.

Step three is the one that a plain calendar app cannot do, and it is the reason the house is still using Chirpy’s calendar in the spring.
