Big Sendies is a climbing logbook built for the gym and the crag. TRACK EVERY SESSION Start a session on your iPhone or Apple Watch and log each climb as you go: grade, style (bouldering, top rope, lead), falls and how you sent it, from flash and onsight to project. Heart rate, calories and height climbed are recorded automatically and show up on your phone as soon as each climb ends. Sessions are saved to Apple Health as workouts. ON YOUR LOCK SCREEN A Live Activity keeps your session on the Lock Screen and in the Dynamic Island: time, climbs, sends and your hardest grade, with an End button when you're done. KNOW WHAT YOU'VE CLIMBED Your route logbook shows every route you've climbed, sortable and searchable, with each attempt and when you first sent it. When you pick a route while logging, you'll see if you've done it before. WATCH YOUR GRADES GO UP Charts and a grade pyramid show your progress over time. Earn achievements as you climb. CLIMB WITH FRIENDS Add friends, follow their sessions in the activity feed, and cheer their sends. BUILT FOR IPHONE DUO Unfold it to see your sessions and routes side by side with their details. FREE AND PRO Log up to 30 climbs a month for free. Big Sendies Pro removes the limit: $2.99/month or $24.99/year. JUST ASK SIRI "Start a Big Sendies session." "Have I sent Blue Crush?" "When did I last climb at my gym?" Start and end sessions, hear a recap, or check a route's history hands-free. Your sessions, routes and gyms show up in Spotlight too.
