What's New in Ntrval Timer
1.6.1
October 28, 2026
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.
