Invite friends and share kindness

Use your invite link, QR code and printable kindness cards to grow your ripple, and share acts so others can pay it forward.

Updated November 2, 2026

Why invites matter

When someone joins ROK from something you shared, they become part of your ripple. Every act they record earns you 5 points, and every act from people further down your chain earns you 1. Your Ripple Pond grows with each new person.

Printable kindness cards

Kindness cards are small printed cards with a QR code. Keep a few with you and leave one with each kind act. When someone scans a card, they can join ROK as part of your ripple.

  1. Step 1: In Share & spread kindness, open Kindness cards to hand out.
  2. Step 2: Choose 10, 20 or 50 cards.
  3. Step 3: Make the sheet: select Generate sheet on the website, or tap Generate printable sheet in the app.
  4. Step 4: On the print page, select Print. If nothing happens on a phone, use your browser's Share menu, then Print.

Tip: Cards fit Avery 5371 business-card sheets, 10 to a sheet. In the print settings, set margins to None and turn off headers and footers.

You can also link a card to one of your acts, so whoever gets it sees exactly what you did. Do it on the screen right after you post: under Link a printed card to this ROK, type the code printed on the card (like ABCDE-FGHJK). On the website you can also use the scan button to read the card's QR code.

Good to know: Linking is only offered right after posting, so keep your cards nearby. A card that isn't linked still works: it invites people to join as part of your ripple.

Share an act

Sharing an act shows people what kindness looks like and invites them to pay it forward.

In the app

Tap the share icon under any act in the feed to open your phone's share menu.

On the website

Select Share under any act in the feed for options like X, Facebook, WhatsApp, email and copy link. On an act's own page, use the buttons under Pay it forward.

Right after you post, Share this ROK gives you a link (Share invite) and a QR code (Show QR) for that act. Anyone who joins from them is marked as inspired by that exact act.

When someone joins from an act link, they're linked to the person who did the act. Sharing your own acts grows your ripple. Sharing someone else's grows theirs. It's kindness either way.

Add who inspired you

Did a friend inspire you to join, but you signed up without their link? You can add them once.

  1. Step 1: Go to Account & settings and find Who inspired you to join?
  2. Step 2: Type their @handle, or paste an act link or invite link they shared. Then tap Find.
  3. Step 3: Check that it's the right person, then tap Yes, that's them.

You'll appear in their Ripple Pond, and they get the points they would have earned from the acts you've already posted.

Good to know: You can only do this once, so double-check. If you don't see Who inspired you to join?, your account is already linked to the person who invited you.

Questions

Which should I share: my invite link or an act?
Both work. Your invite link connects people to you. An act link also shows them what you did, and joining from it connects them to that act.
I changed my username. Do my old links still work?
Links and QR codes that used your old handle may stop pointing to you, so share your new invite link. Printed kindness cards keep working.
