Climbing logbook for bouldering & routes. Track climbs with auto height detection on iPhone or Apple Watch. Analyse your progress with detailed charts. No subscription.
Bloclog is a climbing logbook for iPhone and Apple Watch. Log boulders and routes at the gym or outdoors, record the grade and result of every climb, and follow your progress over time. No account. Works offline. No ads, no analytics. No subscription.
LOG YOUR CLIMBING
• On iPhone or Apple Watch, with automatic height detection or by entering the height manually
• Advanced logging (free) allows you to log the style of the climb (wall angle, type of hold)
• Link attempts of the same problem together, allowing you to compare them and better assess your progress
• Document your thoughts on climbs with a voice note directly from your Apple Watch (automatically transcribes into style of climb as well)
• On Apple Watch only: automatic detection of climb start time, based on barometer, motion sensors and machine learning
SEE WHERE YOU'RE IMPROVING
• Bloclog provides a variety of metrics to see how you are progressing:
• Climbing level: the grade you send about half the time, and how it is moved by each session (uses a Whole-History Rating fit of a Bradley–Terry logistic model)
• Sends, attempts and send rate for every grade
• Grade pyramid, hardest sends and how often you climb
• Monthly and yearly recaps, ready to share as images
• Every try on a project on one chart, from the first fall to the send
EVERY STYLE, EVERY GRADE SYSTEM
• Bouldering, top rope, sport, trad, multi-pitch, deep-water solo and free solo
• V-scale, Font, French, UIAA, YDS, British, Ewbank, Saxon, Kurtyka, Nordic and Brazilian, or your own custom scale, such as your gym's hold colours
• A Font 7A stays a Font 7A. Bloclog never converts your grades.
• Save your gyms and crags, and add notes, wall angle, ascent style and effort to any climb
WORKS WITH THE APPLE ECOSYSTEM
• Climbing workouts in Apple Health, with heart rate and active energy (optional)
• iCloud sync and backup (optional)
• Widgets, Live Activities, Watch complications, Siri and Shortcuts
• Import from other climbing apps and Garmin FIT files, export to CSV or JSON
