Sender Climbing App

This is a public beta. Some features are still rough, data formats may change between builds, and bugs are expected. Turn your Garmin into a real climbing activity recorder. Track multipitch, sport, bouldering, indoor, and ice climbing as proper FIT activities that sync to Garmin Connect — with pitch-by-pitch breakdowns, vertical gain, climb-vs-belay time, grades, ascent style, and post-session analytics. Disciplines: *Multipitch — automatic + manual pitch segmentation, vertical gain per pitch, pitch count, climb-vs-belay time split, approach & descent phases * Sport — send/attempt, ascent style (onsight/flash/redpoint), lead vs top-rope, route grade * Bouldering — attempt counter, send %, rest timers, per-problem grade & ascent style (no GPS) * Indoor — heart rate + time-on-wall for gym sessions (no GPS) * Ice — WI/AI/M grades, built on the multipitch pitch engine * Hangboard — Max Hangs, Repeaters, and custom grip strength protocols with added or removed weight. Under the hood: * Climbing-specific data fields recorded into your FIT activity and Garmin Connect * Barometric-altimeter pitch detection with a manual lap override * Per-discipline post-session summaries on the watch * Crash/restart-survivable recording tuned for long days out Outdoor modes work on Garmin multisport watches with heart rate, barometric altimeter, and GPS (Fenix, Instinct, and similar). Gym modes (bouldering, indoor) run on most Connect IQ watches.
