Features
What the app does today. The web app is open to try; the iPhone app is in closed beta. Launch is planned for early 2027.
Grades per angle
Every problem has its own grade at each wall angle. A 6A at 15° can be a 7A at 45°. The first ascent at an angle sets the grade.
Circuits
Timed sequences of problems with rests in between. The app checks the hold transitions between blocks, and plays the circuit with a timer.
Session logging
Log ascents, attempts and repeats. Each session keeps its times, notes and tags, with a timer if you want one.
Training log
Every climbing day on a calendar. Tap a day to see its sessions.
Statistics
Your ascents, attempts and repeats by grade, and your activity by wall angle.
Feed
Follow other climbers and see what they climb. Like and comment. Each gym has a leaderboard.
LEDs on the wall
The app works without them. With LEDs behind the wall, the holds light up. See the installation guide for how they go in.
Holds light up
Pick a problem and light it up on the wall: green for start, blue for hands and feet, purple for hands only, yellow for feet only, red for finish. In a circuit, the lights follow the blocks.
Jam Sessions
Several climbers share one queue of problems. Anyone can add to it, and up to four phones can be connected to the wall at once.
Hold mapping
Mark the holds on a photo of the wall and give each one the number of its LED. On iPhone, the app can find the holds for you.
Standard parts
LED pixel strings and an ESP32 controller. Phones connect to it over Bluetooth, so the lights need no internet or WiFi.
How sharing works
Every wall has its own holds, so problems belong to the wall they were set on. Anyone signed in can see them. You can follow climbers at other walls, and each gym has its own leaderboard.
