Voice-coached GPS running with pace & cadence alerts. Buy once, no subscription. Run smarter, not just harder. Slipstream Runner is a GPS running tracker with something most trackers don't have: a voice coach that actually pays attention to your pace and cadence while you run, so you don't have to keep glancing at your phone. Real-Time Voice Coaching Tell Slipstream Runner your target pace, your target cadence, or both — it'll call out live audio cues to keep you on track. Choose how it coaches you: • Deviation mode — get an alert only when you drift off your target, so you're not interrupted when you're already on pace • Frequency mode — get a simple check-in every 15, 30, 60, or 120 seconds Dial in the sensitivity (Tight, Normal, or Loose) so the coaching matches how precise you want to run. Accurate GPS Tracking Live speed, cadence, and distance, built on a GPS processing pipeline tuned to reject spurious spikes and glitches — so your stats reflect your actual run, not GPS noise. Run History Review past runs and intervals with speed graphs, and share your results straight from the app. Pay Once, Own It Forever No subscription, no recurring charges. Try it free, then unlock full access with a single one-time purchase. Whether you're pacing a tempo run, holding a target cadence for injury prevention, or just want a running app that talks to you instead of the other way around, Slipstream Runner keeps you focused on the run — not the screen.
