Runo is a metronome application designed specifically for runners to maintain consistent pacing during their workouts. It converts running pace into audible rhythm, allowing athletes to run to a steady beat and avoid the common problem of pace drift that occurs as fatigue sets in.

The app enables users to set their desired cadence anywhere from 120 to 220 steps per minute (SPM). It features Apple Watch integration with haptic beats that work without headphones, social features including friends and leaderboards, Strava synchronization capabilities, and a dedicated treadmill mode for indoor running sessions.

Runo works by generating a consistent beat pattern that matches the runner's target cadence. Users simply set their preferred steps per minute, put in their earbuds or use the haptic feedback on Apple Watch, and run synchronized to the rhythm. This approach helps maintain form and pacing throughout the entire workout duration.

The primary benefits include reduced impact forces and injury risk, improved running economy by up to 10%, and better form maintenance when fatigue hits. Use cases include marathon training, tempo runs, interval workouts, and general running form improvement for athletes of all levels.

Runo targets runners who struggle with pacing consistency, particularly marathon runners tired of inconsistent pacing. The app integrates with Strava for activity tracking and offers social features to connect with other runners. It has achieved a 4.7-star rating on the App Store and is used by over 10,000 runners.
