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.

Ratings & Reviews
This app has not received enough ratings or reviews to display an overview.
Built from coaches’ feedback.
• More reliable timer sound: if iOS silences the app — after AirPlay, Bluetooth, a call or another app’s sound — it brings the sound back on its own, no restart needed.
• Works all day without internet: once you’re signed in, your timers, workouts and calendar keep working, and the TV keeps running if the gym’s internet goes down.
• A longer end beep: on the Long sounds it now rings 50% longer, and there’s a new Extra long.
• Four new countdown sounds — Sport Start, Race Start, Clock Pips and Radio Pips — each in Normal, Long and Extra long. Pick a sound, then how long its end beep lasts.
• Workout timers count rounds at each station — “Round 3 of 8” — and start over when the room rotates.
• Repeat a group of intervals ×N — the phone and the TV count “Round 2 of 4”.
• Back takes you to the screen you came from, and your timers and workouts reopen in the folder you were in.
• On the timeline, tap an interval to start it from the top, or drag to land exactly where you let go.
• The TV menu now shows only the options for the screen you’re on.
• Workout builder: it shows how many rounds each station runs and reminds you to save so the timer updates; number boxes can be cleared and retyped, and the station timing fields line up.
• A smaller, faster app.
