Kerno – Habit Tracker

Kerno is the habit tracker that's on your side. No pressure, no punishment – just your progress.

NEW IN 2.0: YOUR PERSONAL AI COACH
Kerno spots your patterns: your strongest weekday, the time of day your habits work best, and which habit is on the rise. With Apple Intelligence you get a personal daily nudge with one concrete tip. Everything runs on your iPhone – your data never leaves your device.

CREATE HABITS WITH AI
Just type your goal, like “sleep better”. Kerno suggests three small, doable habits. One tap and you're set.

CHECK OFF WITHOUT OPENING THE APP
• Control Center, Lock Screen & Action button
• Interactive widgets for Home and Lock Screen
• Siri: “How is my day in Kerno?”
• Focus filters: see only work habits in your Work focus

PROGRESS THAT MOTIVATES
• Streaks with rest days – one missed day doesn't ruin everything
• Overachieving counts: did more? It gets celebrated.
• Pause & vacation mode freezes your streak
• Rest days, specific weekdays or intervals
• Daily, weekly or monthly goals with amounts and units
• Log retroactively, with notes and mood
