Why Big Sendies
Designed by climbers, for climbers. Every feature exists because someone needed it on the wall.
Log every route and boulder problem with grade, style, attempts, and send status. Sport, trad, bouldering — we've got all disciplines covered.
Core FeatureVisualize your grade progression over time with timeline charts and grade pyramids. Spot weaknesses, celebrate breakthroughs, and watch yourself level up.
AnalyticsAdd friends by username or with a share link, then follow their sessions, new personal bests, and achievements in your activity feed — and react to every send. The crew that hypes you harder than anyone.
SocialSnap a photo of the gym's route card and Big Sendies fills in the route name, grade, setter, set date, and hold color for you. Less typing, more climbing.
Core FeatureUnlock fun goals along the way — log enough vertical feet to summit Everest (three times over), rack up your first 100 falls, tick your first outdoor 5.12. Some serious, some silly, all worth chasing.
MotivationEvery session — tracked on your Apple Watch or iPhone — automatically writes to Apple Health and Fitness — heart rate, active calories, workout duration, and more. Your climbs, in your health data, without lifting a finger.
IntegrationLog climbs, track your heart rate, and start sessions right from your wrist. Real-time stats on the wall — no phone needed. See how it works →

Got Questions?
Quick answers to the stuff climbers ask us most.
Big Sendies reads heart rate, active calories, and workout data from Apple HealthKit on your Apple Watch. If you accidentally denied these permissions when you first launched the watch app, the app can't access that data — but it's easy to fix.
To re-enable HealthKit permissions on iPhone:
Once enabled, start a new climbing session on your Apple Watch and your stats will appear in real time.
Nope! The Apple Watch app is totally optional. You can log climbs, track progress, and use all social features entirely from your iPhone. The watch just adds real-time heart rate, calorie tracking, and the convenience of logging from your wrist mid-session.
Yes — live sessions are saved as climbing workouts in Apple Health and the Fitness app, whether you track them on your Apple Watch or your iPhone. That means your climbing counts toward your Activity rings.
Sessions tracked on Apple Watch include heart rate and measured active calories. Sessions tracked on iPhone alone record duration, with calories estimated from the workout.
Make sure HealthKit permissions are enabled (see above) for this to work correctly.
No worries — you can always add climbs manually after the fact. Open the app, go to your session history, and tap Add Climb on any past session to fill in any routes you missed. Your stats will update automatically.
Big Sendies is free to download, and every feature — progress tracking, Apple Watch support, Apple Health sync, friends, and achievements — is included on the free plan. Free accounts can log up to 30 climbs per calendar month; the count resets on the 1st.
Need more? Big Sendies Pro is an optional subscription that removes the monthly limit so you can log unlimited climbs. See our Terms for details. Have questions? Shoot us an email.
Our Story
Big Sendies started because every existing climbing app felt like it was built by someone who'd never clipped a draw. We wanted something that actually matched how climbers think — session-first, community-powered, and obsessed with the send.
We're a small team of climbers who ship fast and climb often. Every feature gets field-tested at real crags before it ever hits your phone. If it doesn't make the app better on the wall, it doesn't ship.
Whether you're projecting your first 5.10 or chasing a V10 in the gym, Big Sendies is built to grow with you.
