Kern is a sobriety counter for people who want a quiet one. No community feed. No daily streak guilt. No ads. No account. No data collected. Just your day count — on your home screen, in a small widget, in a calm app. Open Kern, see your number. Close it. Live your day. **Built around what matters** • Your day count on the Lock Screen — a ring, a panel, or one line above the clock • A home-screen widget that fits next to your weather and calendar • A clean hero number that grows with each sober day • Milestones from day 1 to 1000 — marked, not celebrated loudly • Start over honestly: log the day it actually happened, and undo a mis-tap • Personal best preserved across resets — relapse doesn't erase your record • Optional money-not-spent, off unless you turn it on • Editable habit label (alcohol-free by default — make it smoke-free, or anything) **Counting more than one thing** Plenty of people are quitting two things at once. Kern is free for your one thing, forever. Keeping more than one is a single purchase — no subscription, nothing that renews. • As many counts as you need, each with its own name, start date and milestones • Swipe on the main screen to move between them — one number at a time, still • A widget showing every count at once, or a small one showing whichever you pick • Each count gets its own reminders, named, so you know which one reached the day Your existing count and everything around it — every widget, milestones, personal best, starting over, editing your own dates — stay free. Nothing you already have moves behind the purchase. **Built for privacy** Everything stays on your device. No accounts, no analytics, no data collected — including when you buy. Apple handles the payment; we never see it. **Not a replacement for support** Kern is a counter, not a clinical tool. If you're in crisis, the SAMHSA National Helpline is free and confidential: 1-800-662-4357. Outside the US, find a helpline at findahelpline.com. One day at a time.

MAKE YOUR MILES WITH RUNLOOP Plan your next route, track a run, and build your running routine. BUILD YOUR ROUTE Choose your distance, a loop or out-and-back, and a starting point at your location or nearby. Choose Balanced, Quiet Roads, Trail & Adventure, or Fast & Smooth, then compare mapped route options, distance, elevation, and disclosed compromises. START RUNNING Start a Quick Run without planning a route. Track time, distance and pace, pause or resume your session, and review completed runs in Activity. Location recording can continue during an active run with the screen locked when permission is enabled. MAKE IT YOURS Choose a workout, set your running preferences, save routes, manage voice guidance, and optionally connect Apple Health. FIND YOUR COMMUNITY Sign in to discover shared routes, follow runners, and participate in RunLoop Community features. Account and Community participation are optional for core route planning and run tracking. A FRESH RUNNING EXPERIENCE A bold new Home screen, clearer controls, readable run metrics, and route-generation progress keep the focus on your run. Routes depend on mapped roads and paths, provider availability, GPS accuracy, internet connectivity, and local conditions. Generated distances may differ from your target; review route details and compromises before starting. Always check traffic, access restrictions, closures, terrain, and weather. RunLoop does not guarantee that a route is safe, accessible, or suitable for you.
