Just climb. We’ll track the rest. Climo is the ultimate rock climbing and bouldering ecosystem for iPhone and Apple Watch, designed to turn your data into serious progression. Forget clunky apps that interrupt your flow—Climo makes logging ascents frictionless so you can save your energy for the wall. Whether you are bouldering at the local gym, studying a topo for sport routes at the crag, or building finger strength at home, Climo brings your entire climbing journey into one powerful logbook. APPLE WATCH AUTO-DETECTION Leave your phone in the locker. The fully standalone Apple Watch app uses smart altimeter algorithms to physically feel when you climb. • Zero Friction: When you land, your watch taps your wrist. Use the custom 3D crown wheel to dial in your grade and log a send in 2 seconds. • Live Telemetry: Monitor your heart rate, elevation gained, and active energy directly on your wrist mid-workout. • Seamless Sync: Climb completely offline. Data queues on your watch and syncs to your iPhone the second you reconnect. THE ULTIMATE LOGBOOK Track every boulder and sport route with precision, whether indoors or outdoors. • Projects vs. Sends: Manage your outdoor projects, track attempts, and log crucial beta tags for your next ascent. • Global Grades Supported: Full support for V-Scale, Fontainebleau (Font), French, and YDS grading systems. • Strava Integration: Auto-upload your climbing workout directly to Strava. ROOT-CAUSE FAILURE DIAGNOSTICS Most apps only track your successes. Climo tracks why you fell to help you crush plateaus. • Failure Engine: Did you pump out? Slip a foot? Mess up the beta? Log failure reasons to identify your exact training blind spots. • Wall-Angle Radar: Visualize your strength across slabs, vertical walls, overhangs, and roofs. AI CLIMBING COACH & HANGBOARD TIMER Turn your session data into structured progression with the "Ascension Architect" AI. • Adaptive Training: Generate personalized, multi-week workout blocks based on your past performance and failure metrics. • Advanced Hangboard Timer: Built-in timer protocols for max hangs and repeaters. • Protect Your Pulleys: Log specific grip types (crimp, pinch, sloper) and track finger load over time to build strength safely. GAMIFY YOUR GROWTH • Climo Points: Earn points dynamically based on grade difficulty and technique, not just pure volume. Watch your score rise live on your watch during a session! • Progression Charts: Watch your max grade increase over time in beautiful, interactive charts.
