Invite links work without a username, so they're the right tool for the paddock or a track day: you hand someone the link (or let them tap it on your phone) and you're connected, no username needed. They also work over chat when you don't know someone's username yet. If you'd rather connect by username instead, see Adding Friends on LapBrain.
Generate and share an invite link
- Open Settings, then Friends.
- Tap Generate invite link.
- Tap the Copy button next to the new link. The app copies a short message with the link to your clipboard, mentioning your @{username} so your friend knows who sent it.
- 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 — no accept step needed, because handing over the link is the consent.
Tap Copy any time to grab a fresh link without leaving the page. Each new link is independent, so you can paste the same link into multiple chats.
How long a link lasts and how many people can use it
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 Copy again on the Friends page to generate 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.
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), LapBrain automatically completes the friend connection. There is no second step the recipient has to remember; the friendship is established at the moment signup finishes.
If the link expires or fills up
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 Settings then Friends and tap Copy again, then forward the new link the same way.
What to do next
- Connect by username instead. If you both know each other's usernames, Adding Friends on LapBrain is the everyday path.
- 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.
