Chronir is the alarm app for everything your regular reminders forget. Rent due on the 1st. Car insurance renewal. Annual furnace inspection. Pet vaccinations. These aren't tasks you can afford to miss โ€” but a silent notification buried under 50 others isn't enough. Chronir treats your long-cycle obligations with the urgency of a morning wake-up alarm: full-screen, persistent, undeniable. HOW IT WORKS Set an alarm for any recurring schedule โ€” weekly, monthly, annually, or one-time. When the time comes, Chronir fires a real alarm with sound and a full-screen alert. No quiet notification. No easy dismiss. You acknowledge it, snooze it, or mark it done. KEY FEATURES โ€” Real Alarms, Not Reminders Full-screen firing with persistent sound. Fires even in Do Not Disturb and on your lock screen. This is an alarm, not a notification. โ€” Flexible Scheduling Weekly (every Sunday), monthly (1st and 15th), annual (Feb 28), or one-time (car registration due March 1). You set it once, Chronir handles the rest. โ€” Siri & Shortcuts "Create an alarm in Chronir" โ€” set alarms by voice or automate them with Shortcuts. Ask "When is my next alarm?" or "Show my alarms" hands-free. โ€” Categories & Grouping Organize alarms by category โ€” Home, Health, Finance, Vehicle, Work, Personal, Pets, Subscriptions. Group view keeps your list clean. โ€” Smart Snooze Snooze for 1 hour, 1 day, or 1 week. Persistent alarms keep firing until you take action. โ€” Wallpaper Personalization Set a custom background photo with pinch-to-zoom and drag-to-reposition. Your alarm list, your style. CHRONIR PLUS ($1.99/month) Unlock unlimited alarms, custom snooze intervals, pre-alarm warnings, photo attachments, and completion history with streaks. Built for homeowners, caregivers, pet owners, freelancers, and anyone who needs long-cycle accountability โ€” not another to-do list.
