Voice-Coached Interval Training and GPS Pace Tracking
SplitCue is a running app designed for runners who want structured interval workouts with hands-free voice coaching. Instead of constantly checking your phone or watch, SplitCue announces your current pace, elapsed time, distance, and interval transitions out loud.
Whether you're doing 400-meter repeats, tempo runs, fartlek sessions, or run/walk intervals, SplitCue guides you through every phase with clear audio cues.
Voice Pace Announcements
Hear your current pace (min/mile or min/km) at configurable intervals — every 15, 30, 60, or 120 seconds — using GPS-based tracking with a rolling average for accuracy.
Interval Timer With Audio Cues
Build structured workouts with warmup, hard, easy, and cooldown intervals. SplitCue announces each transition, tells you what's next, and gives countdown warnings.
AI Workout Builder
Describe what you want in plain English — like "a 30-minute tempo run with strides" — and SplitCue's AI generates a complete interval workout.
GPS Pace Tracking
Real-time GPS tracks your pace, distance, and speed throughout your run. Set target paces on individual intervals and get alerts when you drift off target.
Runs in Background
Lock your phone and keep running. SplitCue continues tracking and announcing in the background, ducking your music volume for cues and restoring it after.
Workout Sharing
Share your workout structures and completed results with other runners via a link. Recipients can import the workout directly into SplitCue.

Problems SplitCue Solves
Constantly checking your phone or watch
Most runners glance at their screen dozens of times per workout to check pace or see when to switch intervals. SplitCue eliminates this by announcing everything out loud. You hear your pace, when to speed up or slow down, and countdown warnings before each transition.
Losing track of intervals during speed work
Trying to remember "was that my 4th or 5th repeat?" is distracting. SplitCue tracks your position in the workout and announces the set number, block name, and what's coming next at every transition.
Building structured workouts is tedious
Instead of manually configuring every interval, you can describe your workout in plain English and let SplitCue's AI builder create it — or pick from 11 built-in presets and customize from there.
Holding a consistent target pace
SplitCue's GPS pace tracking lets you set a target pace on any interval. The app tells you if you're ahead of or behind your target, helping you lock in the right effort level.

SplitCue is available on iOS (iPhone). It works with wired headphones, Bluetooth earbuds, or your phone's speaker.
