Log boulders and routes. On iPhone and Apple Watch.
Bloclog records climbing sessions on iPhone or Apple Watch: the grade and result of each climb, session time, and height climbed from the barometer. Over time you see how your grades develop.
How it works
Start a session, climb as usual, and tap a grade between climbs. Bloclog handles the rest.
-
Start a workout
Pick bouldering, sport climbing or top rope and press start, on your iPhone or your Apple Watch.
-
Climb, then tap the grade
Bloclog notices when you climb and measures how high you went. Back on the ground, tap the grade of the boulder or route and how it went: flash, send or attempt. Works on iPhone or on Apple Watch alone.
Repeat for every climb
-
Review your session
See every climb with its grade and result, plus heart rate and a height profile with each climb marked.
-
Understand your progress
Across sessions, see your send rate per grade and how it changes, so you know when to move up a grade.
Screenshots
On Apple Watch
During a session the Watch shows time, height climbed, heart rate and the number of climbs. Log a climb by tapping its grade; the iPhone can stay in your bag.
The barometer measures how high each climb goes, and the motion sensors suggest when a climb starts and ends. You can later edit this in the app.

Questions
Do I need an Apple Watch?
No. You can record on iPhone, on Apple Watch, or both.
Can I record on iPad?
No. iPad shows your logbook; record sessions on iPhone or Apple Watch.
How do I move my logbook to a new phone?
Turn on iCloud sync, or export your logbook in Settings → Export & import and import the file on the new phone.
Can I import sessions from another climbing app?
From supported apps, yes. In Settings → Export & import, choose the exported session files and check the grade mapping before importing.
Does deleting a session remove its Apple Health workout?
No. Workouts already saved to Health stay there until you delete them in the Health app.
