B-Layer helps climbers find climbing partners. Stop scrolling five different gym WhatsApp groups. B-Layer connects you with compatible climbers across gyms and crags near you — people you'd never otherwise meet. HOW IT WORKS • Build a climbing profile — disciplines (lead, sport, bouldering), grade range, gear, preferred gyms and crags, and when you like to climb. • Post a session request — "looking for a partner, Monday 20:00 at the wall" — or browse climbers in a simple deck. • Match — express interest, or respond to someone's request. When it's mutual, you're connected. • Coordinate in a private 1-on-1 chat, meet up, and climb. • After a session, rate your partner and help keep the community trustworthy. BUILT FOR SAFETY B-Layer is adults-only (18+). You can block or report anyone, and delete your account and all your data from inside the app at any time. IMPORTANT: Climbing is inherently dangerous — you climb at your own risk. B-Layer does not verify skill, certification, or identity. Always assess your partner and your own safety before and during a session. B-Layer is starting in Israel. More cities to come.
