Chronos - Intelligent Alarm

Chronos is a smart alarm clock that adapts to your real life — your holidays, your location, even the sun.

⏰ Reliable above all
Alarms ring at the exact time, over the lock screen, through Do Not Disturb, and after reboots. A built-in reliability checklist verifies your permissions and alarm volume so you're never silently let down.

📅 Smart holiday skipping
Enable smart mode and your work alarm automatically stays quiet on public holidays and the free days you mark. Holiday calendars for your country sync automatically — no more waking up at 7:00 on a day off.

📆 Date alarms
Set an alarm for an exact date — once, every year (birthdays, anniversaries), or a chosen day every month.

🌅 Solar alarms
Anchor alarms to sunrise, sunset, or twilight instead of a fixed time — with an optional offset. Perfect for runners, photographers, and early birds. Computed offline, right on your device.

📍 Location-aware alarms
Make an alarm ring only if you're inside (or outside) a zone you choose — a reminder that fires when it actually matters.

🧠 Wake-up challenges
Stop oversleeping: dismiss alarms by solving math, retyping a number, repeating a pattern, or finding emojis in a grid. Or make it a game: whack the troll, swat a mosquito, match the pairs, tilt your phone to roll a ball through a maze, save a penalty, sink a ship with your cannon, or catch the breakfast order on a tray. Set a snooze limit and stick to it.

Also included
• One-time or repeating alarms on the weekdays you choose
• Per-alarm sounds and vibration
• Home-screen widget with your next alarm
• Sunrise timeline card for your day at a glance
• 34 languages
• Optional account to sync across devices — the app works fully without one; no ads; your alarm data stays on your device

Chronos Premium (subscription or one-time lifetime purchase) unlocks unlimited alarms, advanced wake-up challenges, solar alarms, and location conditions. The core alarm experience is free forever.

Recent changes:
The first time you open Chronos, it now asks you right away whether you want to share anonymous usage data to help improve the app. "Yes" and "No" are just as easy, nothing is turned on unless you say yes, and you can change your answer anytime in Settings. Nothing personal is ever sent — never your alarm names, descriptions or locations.
