LapBrain is more useful when you can compare your sessions to friends who ride the same tracks. The fastest way to add a friend is to send them a share link from the LapBrain app.
How to invite a friend
- Open Settings from the top-right menu.
- Tap 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 @handle so your friend knows who sent it.
- Paste it into iMessage, WhatsApp, Signal, SMS, RCS, or wherever you normally chat with them.
That's it. The link works whether your friend already has LapBrain installed or not.
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.
What the recipient sees
When your friend taps the link in their messaging app, two things happen:
- The chat shows a rich preview card with "Join me on LapBrain", your @handle, and a small logo. Most messaging apps generate this preview automatically from the link.
- Tapping the preview opens LapBrain. If the recipient already has the app installed, the link routes straight into the app. Otherwise it opens in their browser and walks them through the next step.
If your friend is already signed in to LapBrain when they tap, you become friends immediately and the app jumps to the Friends panel so they can see the new connection.
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.
How long the 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 @handle 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 and a new pool of 5 redemptions. 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.
What happens 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 will see your @handle in that message so they know who to ask.
To send a fresh link, head back to Settings then Friends and tap Copy again. Forward the new link the same way you sent the original.
What to do next
- Pick a friend who rides the tracks you ride. Comparison gets more interesting when you have someone on similar circuits.
- 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.
