SetGo Timer

New: workouts run on Apple Watch and live on iPhone, with announcements, controls and countdown on both devices. Plus a new history with a weekly goal.

Your training. Your rules. SetGo Timer is a fully customizable interval timer built for athletes who take their workouts seriously.

Whether you train HIIT, Tabata, boxing rounds, circuit training, or any other interval-based workout, SetGo Timer adapts to your routine. Configure every detail: exercises, sets, work and rest durations, optional prepare and cool down phases. Save your timers, mark favorites, and get started in seconds.

Voice-Guided Workouts Stay focused on your training, not your screen. SetGo Timer announces every phase transition, countdown, and exercise change with clear voice announcements. Choose between two voices. Announcements are in English and work offline because they ship with the app.

Apple Watch App SetGo Timer includes a full standalone Apple Watch app. Your timers sync automatically from iPhone to Watch. Start your workout directly from your wrist, no iPhone required. The Watch app runs its own timer engine with live phase display, countdown rings, and haptic feedback on every transition. While a workout runs on the Watch, the iPhone shows it live, speaks the announcements and can pause, skip and stop it. Start on the iPhone and the paired Watch takes over the workout. Completed workouts land in the history on your iPhone automatically.

Live Heart Rate & Apple Health Track your heart rate in real time during workouts on Apple Watch. SetGo Timer saves completed sessions to Apple Health, including duration, calories burned, and average heart rate. Review your workout history with detailed stats for every session.

Workout History & Stats Every completed workout is saved with full details: date, duration, exercises completed, heart rate, and calories. A weekly goal with a streak keeps you on track and shows your training consistency at a glance.

Haptic Feedback Feel every phase change through haptic feedback on both iPhone and Apple Watch. Never miss a transition, even with headphones off.

Focused Design SetGo Timer uses a clean interface designed to minimize distractions during training, in dark, light or your system appearance. Color-coded phases (yellow for prepare, green for work, blue for rest, purple for cool down) let you see your current phase instantly.
