FULL-SCREEN ALERTS
Every connected display goes full-screen at your lead time — at start, or 1 / 2 / 5 / 10 / 15 minutes before.
MENU-BAR APP · macOS 14+
YOU WILL NOT MISS THE MEETING.
Klaxon throws a full-screen alert onto every display right before your calendar meetings start — impossible to ignore, above every app and Space. When there's a video link, one press takes you into the call.

// THE PROBLEM
TINY NOTIFICATIONS VANISH BEFORE YOU LOOK UP.
You're heads-down in deep work. You context-switch all day. Time blindness is real — and a banner that slides away in four seconds was never going to save you. Klaxon takes over the entire screen, on every display, so the alert is the one thing you cannot scroll past.

// WHAT IT DOES
BUILT LIKE A TOOL.
ONE-CLICK JOIN
Detects meeting links for 30+ services — Zoom, Google Meet, Teams, Webex, Whereby, Jitsi — from URL, location, or notes.
KEYBOARD-FIRST
Return joins. ⌘1/2/3 snooze. Esc dismisses. Every button shows its shortcut — hands never leave the keys.
CONFIGURABLE SNOOZE
Zero to three snooze buttons of your choosing (default 1 / 3 / 5 min), plus a plain Dismiss. Your call.
THEMES & SOUNDS
Ten gradient themes, a Random option, or your own image. Pair it with any macOS system sound — or silence.
CALENDAR-AWARE
Works with every account already in macOS Calendar — iCloud, Google, Microsoft/Exchange. Pick which calendars count.

// VS IN YOUR FACE
A FREE, OPEN-SOURCE ALTERNATIVE TO IN YOUR FACE.
In Your Face is a good paid app — polished, cross-platform, and commercially supported. Klaxon is a free open-source alternative to In Your Face: the same core idea, a full-screen alert you cannot miss before every meeting, built for the Mac. The differences are in the model, not the mission:
| Feature | Klaxon | In Your Face |
|---|---|---|
| Price | Free | $3.99/mo, $24.99/yr, or $69 one-time — free trial with limited alerts |
| Source code | Open source (MIT) | Closed source |
| Account & telemetry | None — reads your calendar locally | No account — anonymous usage analytics & crash reporting |
In Your Face details from inyourface.app, July 2026 — check their site for current pricing.
