Rep: Interval Running Tracker

Rep is a privacy-centric, local-first mobile application designed to help runners structure, time, and pace their running without interacting with a screen mid-stride. Unlike high-cost coaching platforms that dictate multi-week training calendars, Rep operates purely as an on-demand execution utility for athletes who already know their session goals.

Core Capabilities & Features:

  • Screen-Free Pacing Guardrails: Runners can set target pace corridors for their session. If their GPS speed drifts outside the target window, the app fires continuous haptic vibrations and audio prompts to correct their effort.

  • Modular Workout Builder: The app allows users to quickly configure ad-hoc track repeats (such as 400m or 800m intervals), complex pyramids, and ladders. It also supports Progressive Runs that guide pace shifts, as well as Basic Distance runs featuring an automatic halfway turnaround chime.

  • Cadence Metronome: A built-in metronome helps runners lock in their turnover with subtle audio clicks and haptic pulses ranging from 150 to 200 Steps Per Minute (SPM), which smoothly duck underneath background music.

  • Seamless Strava Integration: Rep provides a user-authorized, one-way export of completed activities. It serializes GPS trackpoints, timestamps, and interval splits into a standard .tcx file and pushes it directly to the athlete's Strava account with a detailed lap breakdown.

  • Quick Start (Free Run): For unstructured daily miles, a one-tap Quick Start mode initiates GPS tracking with automatic 1-kilometer audio milestones, bypassing the workout builder entirely.

  • Data Sovereignty & Local Storage: Rep relies on an on-device database, ensuring that all workout history, route maps, and performance metrics remain securely on the user's phone rather than being harvested, pooled, or sold to third parties.

What types of running workouts can I build?

Where is my location and running data stored?

Do I have to follow a structured interval plan, or can I just run?

How do the audio cues work for pacing?

Rep is built on a privacy-centric, local-first architecture. Your complete workout history, location routes, and personal settings are stored strictly on your device's local database. We do not harvest, aggregate, or sell your fitness metrics to third-party ad networks.

You can use the modular builder to quickly create ad-hoc track repeats (such as 400m or 800m intervals), ladders, and pyramids with custom work and rest blocks. Rep also supports Progressive Runs, which guide you through step-by-step distance targets that demand faster splits, as well as Basic Distance runs (like a 5K or 10K) that feature an automatic halfway turnaround chime.

Rep is built for screen-free workout execution. You can set a target pace corridor, and if your speed drifts outside that window, the app fires an instant long vibration and audio prompt to nudge you back into range. You can also double-tap your earbuds for an on-demand audio readout of your elapsed time, distance, and current pace without breaking stride.

How does Rep differ from coaching apps like Runna?

7

While platforms like Runna provide rigid, multi-week coached curriculums, Rep is an on-demand execution utility. It is built specifically for runners who already know what their session is and need a distraction-free tool to hit their paces precisely without staring at a screen mid-stride.

Does the app have a running cadence metronome?

Yes, Rep includes a built-in cadence metronome to help you lock in your turnover. You can set a custom step rate (e.g., 150–200 Steps Per Minute) and the app will play subtle audio clicks and haptic pulses that smoothly duck beneath your background music.
