NextSet - Simple Rest Timer
Gym sets on iPhone & Watch
Free · Designed for iPhone. Not verified for macOS.
NextSet is a simple rest timer for your sets. Tap one of your quick timers and your rest starts. You feel and hear the last seconds on your wrist or iPhone – then it’s time for your next set.
ONE TAP TO REST
• One or two big quick timers on the start screen (1:30 and 3:00 to begin with)
• Up to 12 more timers below, each started with a single tap
• Tap another timer during a rest to switch straight to it
• ±15 seconds, pause and resume, or end your rest early
• When the rest is over, “GO!” counts the time you’ve gone over, and “Repeat rest” starts the same rest again
A COUNTDOWN YOU CAN FEEL
• Signal in the last 3, 5 or 10 seconds – or turn it off
• Strong haptics on iPhone, the Taptic Engine on Apple Watch
• Three sounds: Beep, Chime and Digital. On iPhone they play over your music, which is briefly lowered, and even in silent mode
• Mute the sounds right from the start screen
MADE FOR APPLE WATCH
• Big quick timers right on the start screen, more timers below
• Full-screen ring with countdown, ±15 s, pause and “Repeat rest”, also on the Always On display
• Keeps running with your arm down, so the countdown taps and the end signal reliably reach your wrist
• Timers sync with your iPhone and can be edited on both devices
ALWAYS IN VIEW
• Live Activity on the Lock Screen, in the Dynamic Island and in the Smart Stack on Apple Watch
• A notification when your rest is over while the app is in the background
• The display stays on during a rest (optional)
SIRI, SHORTCUTS & ACTION BUTTON
• “Start Quick Timer”, “Start Rest Timer” with any number of seconds, and “End Rest”
• Start a rest hands-free with Siri or the Action button
YOUR TIMERS, YOUR WAY
• Rename timers, for example “Squats”
• Reorder or delete them – long-press a timer for more options
• Light and dark mode, large rounded digits, Liquid Glass design
PRIVATE BY DESIGN
No account, no ads, no tracking. Your timers and settings stay on your devices.
