DoomClimb is the fastest way to get on the wall and stop scrolling through route lists. Pick a grade, hit Generate, and a fresh climb lights up your Kilter Board — no more cherry-picking your favorites or running out of problems at your level. POWERED BY MACHINE LEARNING DoomClimb uses an on-device Core ML model trained on real Kilter Board climbs to generate routes that feel hand-set, not random. Every problem has a sensible flow, a real start, and a real finish — at the difficulty you asked for. CONNECT TO YOUR KILTER BOARD Pair over Bluetooth and DoomClimb will light up the holds for you, exactly like the official app. Works with the standard Kilter Board LED system. No subscription, no account. DIAL IN THE CLIMB YOU WANT • Set your target grade (V0 through V12+) • Choose angle, style, and hold preferences • Tweak any generated route by tapping holds to add, remove, or reassign them • Regenerate variations until you find one you like TRACK YOUR PROGRESS Every send, flash, and project is logged automatically. Add notes, attach video, and watch your pyramid build over time. The Stats tab shows your hardest sends, your session volume, and your grade distribution at a glance. PLAN BETTER SESSIONS The Session Planner builds a queue of climbs around a goal — warmup, working grade, projects, cooldown — so you walk into the gym with a plan instead of wandering between climbs. SHARE ROUTES INSTANTLY Generated a banger? Share it with a friend as a compact code or link. They paste it in, the holds light up on their board. No accounts, no servers — the route lives in the link itself. BUILT FOR CLIMBERS, NOT SUBSCRIBERS • Fully on-device generation — works without an internet connection • No account required • No tracking, no ads • Your climb history stays on your phone WHO IT'S FOR Whether you're projecting your first V4 or grinding double-digit boulders, DoomClimb gives you an endless supply of climbs at exactly the level you want to work. Perfect for solo sessions, training cycles, or anyone who's tired of repeating the same fifty problems. Get on the wall. Generate. Send. Repeat. Note: DoomClimb is not affiliated with or endorsed by Kilter Board or Aurora Climbing. A compatible Kilter Board with LEDs is required to use the Bluetooth feature; routes can still be generated, viewed, and tracked without one.
