About this app

Log the send. Stay on the wall.

Sendo is a fast, reset-proof bouldering logger built for indoor climbers. Tap the grade, feel the haptic, and get back on the wall — no forms, no friction. Every climb saves to your phone first, so it works in basement gyms with zero signal.

ONE-TAP LOGGING
A grade pad sized for chalky thumbs. Flash, send, or attempt — one gesture each. The grade is the hero; everything else gets out of the way so you spend your session climbing, not typing.

OFFLINE-FIRST, ALWAYS
Every climb lands on your device the moment you tap. No signal in the cave? Doesn't matter. Optional cloud sync keeps your log backed up and mirrored across devices when you want it.

SPEAKS EVERY GRADE
V-scale, Fontainebleau, and Japanese kyu/dan (級/段), natively. Sendo converts across systems automatically, so you can log at any gym, anywhere, without doing math on the wall.

SEE YOUR PROGRESS
Sessions turn into grade pyramids, weekly volume, top tags, and a yearly heatmap of every visit. Watch the distribution of your sends shift as you get stronger.

RESET-PROOF HISTORY
Gyms strip and reset routes every few weeks. Your record doesn't. Sessions, calendars, and stats survive every reset — and you can export everything to CSV or JSON anytime. Your data is yours.

ACHIEVEMENTS THAT EARN THEMSELVES
Unlock a tree of milestones across six climbing disciplines: crimps & fingers, slopers & compression, dynamic & coordination, slab & footwork, overhang & roofs, and endurance & volume.
No claiming, no busywork — they unlock straight from what you log.

NEW TO CLIMBING?
A built-in glossary translates the wall's vocabulary — crimp, drop-knee, sandbag, beta, kyu —with clear illustrations. Long-press any term in the app for an instant explanation.

SHARE THE SEND
Turn a session or a milestone into a clean, shareable send card. Annotate your project photos and show off the line you finally topped.

FIND YOUR GYM
Discover bouldering gyms near you on the map, set your home gym, and choose the grade system per
gym — because walls mix systems all the time.

FREE TO LOG, ALWAYS
The core logging loop is never paywalled. Sendo Pro adds cloud sync, multi-device backup,
unlimited photo and video storage, advanced analytics, and a creator toolset for those who want
more.

Dark-first. Athletic. An instrument for the wall.
