Gamify your climbing with Pebble! Pebble helps you improve your climbing by giving you a grade pyramid to complete each week. Finish the pyramid and move up a level. If you don't, you'll get 2 more tries before you drop back down a level. Each level is tailored to your abilities and helps direct you to climbs that are appropriate for you. In addition to the gamification, Pebble offers these other features: • Follow your friends in the FEED to see their sends and media or your gym to see when a new area has been reset or if any events are happening soon. • Find climbs for your next trip in the OUTDOOR GUIDEBOOK or give back by adding climbs that you've sent to the guidebook through the app in a wiki-style. • Track your nightly sessions at the local CLIMBING GYM if they've joined Pebble or even if they haven't. • Find climbing-specific WORKOUTS & CIRCUITS that other users have created to do specifically at your gym, your local crag, or at home. • Get RECOMMENDATIONS based on your current climbing ability and what climbs you need to send to reach the next grade. • ANALYZE your climbing and training using our charts to see your progress and plan your next sessions. • SCHEDULE workouts and sessions and track your successful completion automatically.
