About
Cadlo — the pro beeper box, rebuilt in your iPhone.
Coaches pay hundreds for a dedicated beep-test box. Cadlo does the same job with the phone already in your pocket and any Bluetooth speaker: beeps cadenced to the centisecond that drive your tests and interval sessions, from the first stage to the final sprint.
EVERY FIELD TEST — IN ONE APP
Most apps run a single test. Cadlo brings the whole toolbox of the pro beeper box together:
• Continuous aerobic tests — VAMEVAL, Cooper (12 min), half-Cooper
• Shuttle & intermittent tests — beep test (20 m shuttle / Léger / PACER), Yo-Yo, Gacon 45-15, 30-30, 15-15
• Circuits — strength & CrossFit stations with transition beeps
• Custom intervals — build your own protocol: work/rest, reps, sets
MAS (maximal aerobic speed) computed from the last completed stage, full session history, athlete management and report export (CSV, JSON, visual card).
TOOLS FOR THE FIELD
• Stopwatch with laps
• Tab-odometer — distances and cone placement for any target speed
• Sprint — frame-by-frame video timing with augmented-reality gate placement
SOUND BUILT FOR THE FIELD
Cadlo is built to keep running with the screen locked and in the background, and designed to play through a Bluetooth speaker. Start the session, drop the phone in your pocket, and coach.
