Invite links are the quickest way to connect in the paddock: hand someone the link (or let them tap it on your phone) and you're connected. They also work over chat. If you'd rather search by username, see Adding Friends on LapBrain.

  1. Open the LapBrain menu and choose Friends.
  2. Under Share an invite link, tap Generate.
  3. The new code appears under Active invite codes. Tap Copy next to it. The app copies a short message with the link to your clipboard, mentioning your @{username} so your friend knows who sent it.
  4. Hand them the link in person, or paste it into iMessage, WhatsApp, Signal, SMS, RCS, or wherever you chat.

The link works whether your friend already has LapBrain installed or not. When they tap it and they're already signed in, you become friends immediately and the app jumps to the Friends panel. Sending the link is the consent, so there is no accept step.

tip

Tap Generate any time to mint a fresh link without leaving the page, then Copy next to it. Each link is independent, so you can paste the same link into multiple chats.

A single invite link is good for:

  • Up to 5 different people, and
  • 7 days from when you generated it.

Whichever runs out first ends the link. After that, anyone who taps the link gets a friendly error message guiding them to ask you for a new one (showing your @{username} so they know who to ask).

You can always tap Generate again on the Friends page for a fresh link with a new 7-day window that 5 more people can use. The old link still works for anyone you sent it to recently, up to its own limits.

note

The same link can be shared with multiple people. If you're inviting a small group, one paste into a group chat is enough as long as no more than 5 of them end up tapping it within the 7-day window.

If your friend doesn't have a LapBrain account yet

Tapping the link takes them to a signup screen. After they create an account (email + password, or sign in with Apple / Google), the friendship is in place the moment signup finishes.

If the link is past 7 days, or if 5 people have already used it, the next person to tap it sees a message asking them to request a new link from you. They'll see your @{username} in that message so they know who to ask. Head back to Friends in the LapBrain menu, tap Generate again, then forward the new link the same way.

What to do next

  1. Connect by username instead. If you both know each other's usernames, Adding Friends on LapBrain is the everyday path.
  2. Compare your sessions. Once you're connected, your friends' sessions show up alongside yours where the analysis supports peer comparison. See Comparing Laps Effectively for what to look at first.
