Ahem: Calendar Alarm Clock

Calendar notifications are easy to miss. A quiet ping, a banner you swipe away — and ten minutes later you're the person joining late. Ahem bridges that gap: it reads your device calendar and rings a real alarm before your events, automatically.

Set it up once, then stop thinking about it. That's the whole point — less stress, not more productivity theater.

HOW IT WORKS
• Ahem watches the calendars you choose (Google, Exchange — anything synced to your device)
• New events get an alarm automatically, with the lead time you set (e.g. 10 minutes before)
• The alarm is a full-screen, sounding alarm — not a notification. It wakes the screen, plays over the lock screen, and keeps ringing until you act

BUILT FOR RELIABILITY
• Uses Android's alarm-clock priority (the same mechanism as your wake-up alarm)
• Alarms survive device reboots — even a restart overnight while the phone is still locked
• A built-in reliability self-check warns you if your device's battery settings could interfere
• Time-zone and daylight-saving aware

STAYS OUT OF YOUR WAY
• Choose which calendars to track, silence, or ignore
• Per-calendar quiet hours, vacation mode, and pause
• Keyword rules: auto-ignore "tentative" placeholders, get prompted to pause for "vacation" events
• Recurring events are recognized as series — set one lead time for the whole series
• Quick-set an alarm straight from the new-event notification

MAKE IT YOURS
• 20 hand-picked alarm tones, or use your own
• Gentle visual pre-phase before the sound starts, so a glance is enough
• Vibration patterns, per-alarm customization, snooze and auto-snooze
• Dark-first design that's easy on groggy eyes

PRIVATE BY DESIGN
• No account. No sign-up. No ads.
• Your calendar never leaves your device — Ahem has no server and sends nothing anywhere
• Read-only calendar access
