This is a no-fuss fitness timer: - Set timer duration - Set timer repeat amount - Set rest time between repeats - Remembers your settings for next time

Splitr is a smart pace calculator for runners, cyclists, and anyone who thinks in splits. Enter any two values — speed, pace, distance, or time — and Splitr instantly calculates everything else. No tapping a button. No switching screens. Just the numbers you need, the moment you need them. **How it works** Type a distance and a time, and Splitr shows you your pace and speed. Type a pace and a distance, and it tells you your finish time. Change any field and everything updates live. **What you can calculate** - Speed in mph and km/h - Pace per mile and pace per kilometre - Distance in miles and kilometres - Total time in hours, minutes, and seconds **Distance shortcuts** Tap 800m, 1.5K, 3K, 5K, 10K, Half Marathon, or Marathon to instantly set the distance — then just enter a pace or time to get everything else. **Built for clarity** A clean, dark interface keeps the focus on your numbers. Fields you've entered are highlighted in blue. Derived values are calculated automatically and shown in a distinct style so you always know what you typed vs. what was worked out. **Save your presets** Save any calculation with a custom name. Restore it with one tap. Reorder and rename your presets whenever you like. Your presets sync automatically across your devices via iCloud. **Home screen widget** Add the Splitr widget to your home screen to see your most recently saved preset at a glance — speed, pace, distance, and time — without opening the app. **Share results** Share any calculation via text, email, or any app on your phone. **100% free. Privacy-respecting.** Splitr is free and always will be. No subscription. No sign-up. No ads. No personal data collected — just anonymous, non-identifying usage diagnostics. Your presets sync across your devices via your own iCloud — we never see them. Network activity is limited to that iCloud sync, Apple's StoreKit for the optional tip jar, and the anonymous diagnostics. Every feature is free, no strings attached. Whether you're planning a marathon, checking your tempo pace, or converting a training plan from miles to kilometres, Splitr gives you the answer before you've finished typing.
