Custom interval timers for workouts, tasks & breaks. Set work/rest durations, track your sets, and stay on pace with audio cues. Simple, fast, and distraction-free.
IntervalTimer - Train On Your Terms
IntervalTimer is a clean, customizable interval timer built for workouts, focus sessions, and recovery breaks. Set your work duration, rest duration, and number of sets , then let the app keep you on pace with audio cues and a visual progress indicator.
Your data stays on your device.
IntervalTimer collects no personal data and has no account system. Everything - your workout history, body metrics, timer configurations, and intentions - is stored locally using Apple's SwiftData framework. Nothing leaves your phone. There are no servers, no cloud sync, no analytics pipelines, and no third-party SDKs tracking your behavior.
The optional body metrics (weight, height, sex) you enter for calorie estimates are saved only in your device's local storage via UserDefaults. They are never transmitted, never shared, and never used for any purpose beyond the in-app calorie calculation you see on screen.
Features:
- Fully customizable work/rest/sets intervals
- Audio cues for transitions and completion
- Workout history log with session details
- Calorie estimates based on your local profile
- Intentions tracking to reflect on your mindset
- Pre-configured templates to get started fast
- Siri Shortcuts and Spotlight integration
- Works entirely offline - always
No ads. No tracking. Just a timer that works.
Disclaimer:
Calorie estimates are educational only and not a substitute for medical advice.
Consult a healthcare provider before making health decisions.
