Family organisation app
Family life, a little calmer.
Calendar, messages, expenses, paperwork, baby tracking: everything that keeps the household running, shared in one place. And when the tone rises, Serenity helps you say things differently.

When the tone rises, Serenity helps you say things differently.
Everything in one place
One app for the whole household.
Eleven spaces to switch on depending on your family. Each person chooses which ones to show: nothing clutters your screen, nothing gets lost.









Calmer messages
The message goes. The argument doesn’t.
Inspired by nonviolent communication, Serenity rereads your message before it is sent and suggests a calmer version. You stay free with your words.
- You writeThe way you think it, in the moment.
- Serenity suggestsIt spots the tense tone and suggests a wording that keeps the substance.
- You chooseSend the calmer version, or your own. If the tone is very sharp, Serenity suggests a few minutes’ pause.
Shared expenses
Clear accounts, down to the cent.
School lunches, nappies, dance classes: everyone logs what they pay, Serenity works out each person’s share and tells you who owes what.
- Your split50/50, 60/40 or in proportion to income, editable at any time.
- Joint account or separated parentsFor separated parents, the other parent approves each expense before it counts.
- Recurring expensesSubscriptions, maintenance, school meals: set up once, counted every month.
- Live and up to dateAn added expense instantly appears for the other parent.
