VaivénBuilt around Spain’s rules.
Your region’s school year is already loaded. Holidays alternate in even and odd years, child maintenance goes up with the Spanish CPI, and extra expenses follow what you agreed.
Your children’s schedule, sorted.
Who’s got the children today? Which school holidays are yours? Vaivén keeps track, so you don’t have to.
The calendar is free. The rest is €9.99, once.
It isn’t on the App Store yet. We’ll email you the day it’s out.

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 judgment.
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
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 judgment. If you get on well, or the children live mostly with you and the other parent has them for visits, it works for you too. You share the calendar if you want, and the schedule fits whatever you’ve agreed.
If there’s violence or you’re afraid, an app isn’t the right tool. In Spain you can call 016 (the domestic abuse helpline).
We’ll email you once, on launch day.
Your email app opens with the message ready. There’s no form, so we don’t store anything.
