Ntrval Timer

Ntrval is an interval timer built for how people actually train — fast to set up, clear to read across the room, and flexible enough for everything from a quick Tabata to a full coached session.

Design a timer in seconds: set your work and rest intervals, rounds, colors, and sound cues, then hit start. Or build a complete workout from your own exercises and let Ntrval generate the timing for you.

CUSTOM INTERVAL TIMERS • Work and rest intervals, rounds, and structure your way • Per-interval names, colors, and sound cues • A big, glanceable display you can read mid-set • Countdown beeps, transition cues, and vibration

WORKOUT BUILDER • Build sessions from stations and exercises • Warm-ups and finishers • Timing generated automatically from your workout • Save workouts as reusable templates

EXERCISE LIBRARY • Keep your movements, equipment, and notes in one place • Attach video links for form reference

PLAN YOUR WEEK • Schedule timers and workouts on a calendar • Keep your training organized from anywhere

RUN IT ON THE BIG SCREEN • A clean, full-screen TV display mode — AirPlay or screen-mirror to a TV for gyms, studios, and group classes

ALSO INCLUDED • Stopwatch and alarms • Works offline — your timer runs even without a connection • No ads. No tracking.

Whether you train at home, coach clients, or program classes for a studio, Ntrval keeps the timer out of your way so you can focus on the work.
