What's New in Kern
0.3.0
July 29, 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.
