Kern

One day at a time.

Sobriety isn't a streak to optimize. It's a series of small, private decisions — made over and over — that nobody else needs to clap for. Kern is built around that idea.

It doesn't ask for your attention. There are no daily reminders to log in, no leaderboards, no community to perform for, no streak you can break. It opens to a single number. The number you chose. That's the whole app.

The milestones — seven days, thirty, ninety, a year — arrive without fanfare. A short message. A small acknowledgment. Then back to the day. No confetti, no badges, nothing to share unless you decide to. The recognition is for you, not for an audience.

It's a tool, not a coach. A glance, not a feed. The app's job is to be there when you reach for it — on your home screen, in a small widget, on your lock screen — and to disappear when you don't.

What Kern does

• A clean hero number that grows with each day you choose yourself.
• Quiet milestones at seven, thirty, ninety, and three hundred sixty-five days.
• A small home-screen widget that fits next to your weather and calendar.
• A personal best preserved across resets — relapse doesn't erase the days you already lived.
• An editable label, so the counter says what you're actually counting.

What Kern doesn't do

No accounts. No community feed. No notifications outside your milestones. No analytics, no servers, no third-party tracking. Apple's privacy questionnaire for Kern reads "no data collected" because that's true — everything stays on your device.
