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.

  1. You writeThe way you think it, in the moment.
  2. Serenity suggestsIt spots the tense tone and suggests a wording that keeps the substance.
  3. 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.
