VowShareI promise to...

Say it, and it's forgotten.
Share the vow, and it's honoured.

Make a promise. Put it on a card. Sign it, send it, honour it.

Experiences and time, not things.

How it works

Seven taps, no typing.

Pick who it's for, the occasion and the promise — or write your own, or just say it out loud. Choose a style and a tone. Add a photo of them, or of the two of you. VowShare writes the card and draws it in about ten seconds.

Just send the picture

Straight to WhatsApp like any photo. Done in a minute. Perfect for a laugh, a birthday, a thank-you.

Send it properly

They get a link, open it in their browser — nothing to download — and sign to accept with one tap. Now it's a promise that lives in both your pockets: gentle reminders, a nudge button for them, and a Kept button for the day you honour it.

Two ways to send

Send a promise, or ask for one.

"I promise to..." is when you're giving. "I promise to take you to the seaside before the summer's out." You sign it, they sign to accept.

"You owe me..." is when you're owed. "You owe me a coffee, Dave. You know you do." Dave opens it, taps I promise, signs — and it flips into a promise from him.

Every "I promise", documented. Every one, signed by both.

VowShare card: You owe me a coffee, Dave. You know you do.

You Made My Day
No strings. No catch. Just gratitude.
Make Their Day

The same idea, pointed at strangers.

The nurse, the bus driver, the person who helped with the pram. Most of us have wanted to thank them and had no way that wasn't awkward. A small token with a QR code. Hand it over. They scan it and get a real thank-you from a real, named person.

How Make Their Day works

Safe by design

No shaming. No pressure. The recipient is always in control.

You see who a card is from before you open it. You can decline quietly, and the sender never knows. Nobody sends anonymously, every card is checked before it's sent, and any promise can be declined, muted or blocked. Read our promise to you.
