"Sent Midnight Lightning second go, crimps were perfect in the cold. Worked on Thriller after, about 15 attempts, got to the last move twice but got pumped.”

Just talk about your climb.
We'll handle the logbook.

Log any session, gym or crag, in plain language. SendSage handles the rest, linking your climbs to the right routes, filling in metadata, and learning your home walls and habits over time.

The SendSage session logger with a climbing session typed into the description box in plain language

Describe it.
That's the whole entry.

Type your session the way you would tell a climbing partner about it. No dropdowns, no grade pickers, no hunting for the route. SendSage reads the sentence and turns it into a structured log.

  • →One sentence covers a whole session, gym or crag.
  • →Routes, grades, and pitch counts come out structured.
  • →SendSage learns your home walls and habits over time.

A logbook that keeps itself

Years of climbing on one timeline. Every entry links back to the real route and area, so grades, pitches, and areas stay right without you maintaining them. Filter by status and see the seasons you actually showed up.

The SendSage logbook: an activity heatmap above linked sessions showing route, area, grade, and pitch details
The SendSage sport dashboard: a grade pyramid, an effort breakdown, and open projects with their attempt history

See your climbing clearly

Your grade pyramid in every discipline you climb, the effort that went into it, and the projects still open. An honest picture of where you are and what to work on next.

  • →A pyramid per discipline, from the board to trad.
  • →Effort broken down by how hard it was for you.
  • →Open projects with every attempt and note attached.

Celebrate how far you've come

Your hardest send in every discipline, the route that earned it, and every state and season you've climbed through.

Hardest sends by discipline, each with the route that earned it and where it was climbed

Why I built SendSage

I'm Isaac. I've been climbing for six years, mostly clipping bolts and placing gear around Colorado. Alpine climbing is my passion, and I live for those big days up in the thin air. SendSage started as a way to turn my own climbing data into real answers about progress.

More than 500 climbers used the earlier versions, and their feedback rebuilt it into this beta.

The beta is free, and I read every bug report and feature vote myself. If something's broken or missing, tell me in the app.
