Neurotic Fitness Trainer

Eyes-Free interval training for sprints and runs - build the workout, run it, and let the voice cues call your splits, targets and what's next. Now with Apple Watch calls

Neurotic Fitness Trainer is a focused interval coach for people who train by effort, not fluff. Build exactly the workout you want, then run it hands-free while it calls out your splits, targets, and what's coming next.

TWO TRAINERS • Sprint — short max efforts with heart-rate-based recovery cues. • Running — distance intervals, continuous runs, and tap-timed waypoint courses.

BUILD IT YOUR WAY • Segments, legs, and reps — distance or time based, each with its own RPE. • Continuous efforts, or a timed "float" recovery between them. • Save your workouts and reuse them.

WAYPOINT COURSES (no GPS guesswork) • Tap at each landmark to bank a split — the app times it, no distance estimation, no bogus numbers. • Set target times per waypoint and hear whether you're ahead or behind. • Seed targets from a previous run of the same course.

VOICE CALLOUTS + APPLE WATCH • Start and drive workouts from your iPhone or Apple Watch. • Hear your splits, totals, and next effort — through the watch and AirPods even with your phone pocketed.

TRACK WHAT MATTERS • Heart-rate zones (Max-HR or Friel LTHR), personal bests, and per-session history with the conditions you ran in.

PRIVATE BY DESIGN • No account, no ads, no tracking. Your data stays on your device. YOURS, COMPLETELY • 100% free. No premium tier, no locked features, no ads, ever. • No accounts, no feeds, no leaderboards — this isn't a community, it's your private training lab. Your data stays on your device. • No AI coach telling you how to feel. You set the effort; the app keeps the receipts.
