How can we help?

One of you installs VOW on your iPhone and starts the wedding: your two names and the date. There's no account, no email and no password. Then start your Heart, and check Up next on Home for what to tackle first.

Yes. Open Alex & Sam's sample wedding from the first screen, or later from More, then See Alex & Sam's wedding. Every section is filled in, with a short tour. Your own wedding is untouched.

Open More, then Link our phones, and send the invite by text. It holds a short code (like VW-7KQ2-M9PD) that works for 2 days. Your partner installs VOW, taps Join my partner and enters the code. If you're together, they can tap Scan their code instead. Your phones are then linked, planning the same wedding.

No. Every feature is free and there's nothing to buy. Download during our Founders release and VOW stays free for you, even when VOW Complete arrives for new couples. See Light and VOW Complete.

Yes. Add the VOW widget to your Home Screen or Lock Screen for the countdown, how far along you are and the next milestone. Turn on reminders in More, then Reminders, for milestones, fittings and the countdown.

VOW is an iPhone app, on the App Store. Android: in development. There's no web version.

Go to More, then What applies to us, and switch off anything that isn't part of your day. It disappears from your plan, and nothing you've written is lost. Switch it back on any time.

Once your phones are linked, there's nothing to do. Each change reaches the other phone in a second or two while VOW is open, or the next time it opens, even when you're apart. Changes travel sealed through our postbox, so only your two phones can open them. You can also sync in person with no internet: both open More, then Sync in person by scanning codes, and scan each other's code. It's animated, so hold the camera on it for a few seconds.

Where you both changed the same thing, the most recent change wins. Everything else from both phones is kept.

Photos stay on the phone that added them. They aren't part of the sync, so a mood board or venue photo you add is on your phone only. If you want your partner to have it, send it to them the usual way, and they can add it on theirs.

Your wedding is part of your normal iPhone backup, so restoring your new phone from your iPhone or iCloud backup brings it across. If that's not possible, install VOW on the new phone, tap Join my partner and link with your partner's phone again to bring the plan back. Photos you added on the old phone come back only from a backup.

No. Your written answers never leave your phone. Once you've both finished, syncing carries only the multiple-choice answers needed to compare, and VOW shows the two of you where you already agree and what's worth a conversation, never the answers themselves.

No. Your Hearts are never included in a PDF or a read-only link.

Twelve short steps, about ten minutes.

Go to More, then Planners & suppliers, and choose the sections they help with, say the venue or running the day. Send a read-only link that stays up to date as you plan, or a PDF of just those sections. They don't need the app and can't change anything. Turn a link off any time in More, then Read-only links.

Plan them in The Send-Offs or After-party, then hand that party's plan to its organiser as a PDF.

Use Hand it over, on the home screen or in More. It makes the whole plan as a PDF for whoever runs the day: a coordinator, the venue or a friend. Your Hearts are never included.

Yes. Everything saves on your phone as you type. If your phones are linked, your partner sees your changes straight away; if not, the next time you sync.

In the app, go to More, then Delete everything on this phone, or simply delete the app. That removes the wedding from that phone. If your phones are linked, Delete everything also unlinks them, turns off your read-only links and deletes your locked copies from our postbox. Your partner's phone keeps its own copy until they do the same. There's no account, so there's nothing else for us to delete. See Privacy for the detail.
