Release notes

Every version of Kern, newest first. The App Store only shows the latest one; the rest are kept here.

0.5.1 · September 2026

Small things, done properly.

• Tapping a milestone notification now opens the count it was about — not whichever you looked at last.
• Money not spent works on every count, not only the first. Set it from the count's editor.
• The background reaches the edges of the screen when you have more than one count.
• "Need help now?" is one tap away at the moment you log a slip, as well as in Settings.
• A milestone that arrives while the app is open is shown instead of silently dropped.

Nothing about your existing count changes.

0.5.0 · September 2026

Count more than one thing.

Some people are quitting two at once — a drink and a cigarette, a cigarette and a vape. Kern now holds as many counts as you need, each with its own name, start date and milestones. Swipe on the main screen to move between them.

• A widget that shows every count at once, and a small one for whichever you pick
• Each count gets its own reminders, named, so you know which reached the day
• Start over on any count, with the same honest slip date and undo

Your existing count stays exactly as it was, and free — along with every widget, milestone and your personal best. Keeping more than one is a one-time purchase. No subscription, ever.

0.4.0 · August 2026

Kern now speaks your language.

The whole app — the day count, the milestones, the notifications that arrive on day 7 and day 90 — is now in 17 more languages. Nothing changed about how it works. It just stopped being in English.

• Spanish, German, French, Portuguese, Italian, Dutch, Polish, Swedish, Danish, Norwegian, Finnish, Czech, Greek, Romanian, Hungarian, Ukrainian and Turkish
• Day counts follow your language's own grammar, not English's — "5 dní", not "5 den"
• Dates, numbers and currency follow your region

As always: no account, no ads, no data collected.

0.3.0 · July 2026

Kern on your Lock Screen.

Your day count now lives where you actually look — a small ring, a wide panel, or a single line above the clock. Glance without opening anything.

• Lock Screen widgets — circular, rectangular and inline
• Start over now asks when it happened, so a slip you log days later doesn't cost you the days since — and there's an Undo if you tapped by mistake
• Optional "money not spent", off until you set a weekly figure
• New milestones at 150, 273 and 730 days, so the long stretches aren't silent
• Progress now measures the stretch you're in, not the whole count

As always: no account, no ads, no data collected.

0.2.0 · June 2026

Share your milestones.

You can now turn any day count into a quiet, shareable card — straight from a milestone, or any day from the main screen. Made on your device, nothing leaves your phone.

• Shareable milestone cards
• A share button on the main screen, share any day

As always: no account, no ads, no data collected.

0.1.1 · May 2026

A bigger widget.

• Added a medium-size home-screen widget
• Tapping "Rate Kern" in Settings now opens the App Store review composer

0.1.0 · May 2026

Kern's first release.

A day counter on your home screen: one number, milestones from day 1 to 1000, a personal best kept across a reset, and a label you name yourself. No account, no ads, no data collected.
