Questions

Does the other parent need to install the app?

No. Only you use it. Whenever you want, you send them a PDF or an image of the calendar or the expenses, and you see what you send before it goes out.

Do I need an account?

No. There’s no sign-up and no password. You only need your Apple ID to buy, as with any app.

Does it work as evidence in court?

No. Vaivén isn’t an official record and doesn’t promise to work as evidence. It helps you keep track of what you agreed, with clear dates and amounts. It isn’t legal advice and doesn’t replace your agreement or court order.

When does it launch?

The app isn’t on the App Store yet. Press the notify button and we’ll email you the day it’s out.

Who it isn’t for

Only you use Vaivén. If the two of you need a chat, or a record that a court asks for, other apps do that. Vaivén isn’t an official record and doesn’t replace your agreement or court order.

If there’s violence or fear, an app isn’t the tool. In Spain you can call 016.
