Chain Day

SJA LOCKSMITHS LIMITED

About this app

ChainDay turns the simple idea of "don't break the chain" into a daily ritual you'll actually keep. Pick the habits that matter — workout, read, meditate, hydrate, study, journal — and check them off each day to grow a visible streak. Miss a day, the chain breaks. That single rule is the entire motivation engine.

No accounts. No subscriptions. No noise. Just you, your habits, and a chain that grows every time you show up.

WHY CHAINDAY
• A pure, distraction-free habit tracker built around one mechanic: the chain.
• Designed for the long game — small daily wins compound into lifelong habits.
• Beautiful, calm interface that gets out of your way.
• Fully offline — your habits stay on your device.

KEY FEATURES
• Unlimited habits — track everything from "drink water" to "30 min deep work".
• Daily chain counter for every habit, plus your all-time longest streak.
• Global stats: current chain, best chain, total completions, missed days.
• Last-30-days completion chart so you can see momentum at a glance.
• Per-habit history and milestones to celebrate every 7, 30, 100, 365 day mark.
• Ovation screen — a clean stats hub that shows exactly how far you've come.
• Lightweight, fast, and respectful of your battery.

1. Add the habits you want to build.
2. Tap to mark each one done today.
