Switch Family Apps Without Losing Your Lists

Ammar Khatib · 14 September 2026

Moving a family from one organiser app to another fails in a predictable way, and it is almost never on day one.

Day one is fine — you are motivated, you enter things, it feels clean. Day three is when somebody opens the old app out of habit, adds something there, and nobody else sees it. By the end of week one there are two half-true calendars, and the family goes back to asking each other, which is where they were before any app existed.

The fix is not a better app. It is running the switch as a planned two-week overlap instead of a clean break.

Why the clean break fails

A clean break asks four or five people to change a habit on the same day, with no fallback. Any one of them forgetting breaks trust in the new system for everyone.

It also throws away your safety net at the exact moment you need one. If the new app turns out not to fit, you want the old one still populated, not deleted.

The two-week overlap plan

Days 1–2: move the calendar.

Most calendar apps publish a read-only feed (an ICS link) that another calendar can subscribe to. If yours does, subscribe to it from the new app. Now the new app shows the old app's events without anyone re-typing anything, and it stays current while the old one is still in use.

If your old app has no feed, do not hand-type a year of events. Enter the next six weeks and the fixed points beyond that — school terms, birthdays, holidays, anything already booked. The rest was never going to be looked at.

Days 1–2: move the lists by copying, not recreating.

Shopping lists, to-do lists and recipes almost never export as a file. What they usually do is print, or show on a web page you can select text from. Copy the text out, paste it into a note, then paste it into the new app.

Two rules. Only move active items — a to-do list carries years of dead entries and moving them poisons the new app on day one. And do the recipes you actually cook, not all of them; most recipe boxes contain forty saved recipes and eight that get made.

Days 3–14: both apps stay installed, one is authoritative.

Announce which one is real. Everything new goes in the new app. The old one is open for reference only.

When somebody adds something to the old app — and they will — do not be annoyed, just move it across and say so. Two weeks of that and the habit turns over.

Day 14: the cut-over.

Check three things before you commit. Has everyone other than you added at least one thing? Do the next four weeks look right in the new app? Is anything still only in the old one?

If yes to the first two, remove the old app from everyone's phone on the same day. Leave the account alive for now.

Day 30 or so: close the old account.

Once you are sure, close it properly. Check whether deleting your account deletes the whole family's data — many family apps work that way, and someone else may still be relying on it.

Moving birthdays without losing the years

A small thing that catches people out.

Birthdays exported as calendar events often come across as a repeating event starting this year, and the birth year is lost. If the year matters to you — and it does the moment somebody asks how old an aunt is turning — check a couple of entries after moving, and re-enter the year where it has gone.

Recurring events in general are the ones to spot-check. A weekly fixture usually survives; anything with an unusual pattern often does not.

What you will lose, honestly

Some things do not come across, and it is better to decide in advance that you are letting them go.

• Completed history. Old finished to-dos, past shopping lists. Nobody has ever missed these.
• Photos attached to events, in most cases.
• Comments and chat threads attached to items.
• The exact structure of nested lists or custom categories.

If any of those genuinely matter, screenshot them before you close the old account. That is a five-minute job and it beats discovering it afterwards.

Do the shopping list first

If you only do one thing from this article, move the shopping list before you move anything else.

It is the feature with the most immediate payoff — everyone feels it within two days, at the supermarket — and it is the easiest habit to establish. A family that has successfully moved its shopping list will move its calendar. A family that starts with the calendar often never gets to the list.
