Build better habits. Reduce the ones that don’t serve you. Systemic Habits is a simple and structured habit tracker designed to help you build daily routines, improve productivity, and reduce unwanted habits — all within one clear system. No pressure. No complex scoring. Just consistency. --- WHY SYSTEMIC? Most habit apps focus only on building habits. Systemic does both: • Build habits that move you forward • Break habits that hold you back Because real change is not just about adding more — it’s also about removing what doesn’t belong. --- HOW IT WORKS • Simple daily check-in: Done or Not Done • No streak pressure, no progress bars • Focus on awareness, not perfection • Track both positive habits and limiting patterns Small actions, repeated daily, shape long-term identity. --- KEY FEATURES • Smart Habit Tracking • Custom Reminders • Life Categories • AI Habit Suggestions • Cloud Sync • Export Your Data • Archive & Recovery • Multiple Languages • Clean, minimal design --- WHO IS THIS FOR? • People building a morning or evening routine • Anyone working on self improvement • Students improving focus • Professionals improving productivity • Anyone looking for a simple habit system --- Systemic is not about motivation. It’s about building systems that last. Start small. Stay consistent.

Miss one. Never two. Two Days is a habit tracker built on one rule: skip a day if life gets in the way, but never skip two in a row. One missed day is a pause. Two is how habits quietly die. Most habit apps punish you for the day you missed. Two Days gives you the pass, then gets you back. TRACK HABITS YOUR WAY Simple check-offs, numeric goals (glasses of water, pages read), timed sessions, or photo proof. Every habit gets its own color, icon, and cover photo, so your routine looks like yours. THE WARNING THAT MATTERS Miss a day and Two Days marks the habit at risk, not failed. One clear nudge, one day to answer it, and a comeback that is easier than starting from zero. STACK YOUR ROUTINES Group habits into Morning, Evening, or any block you like, and clear the whole stack in one pass. FOCUS AND A CHECK-IN Start a timer and stay with one habit until the session ends. When you finish, leave a short note. The mood stays on that day. THE WEEK, NOT JUST THE DAY A weekly review, milestones, and short programs when you want a plan instead of another blank list. CIRCLE Share the rule with someone. They can see you kept it. REMINDERS THAT LEARN Two Days notices when you usually finish each habit and moves the reminder toward that time. INSIGHTS WORTH READING Streaks, a year of days, your strongest weekdays, and the time of day you actually show up. See which habits make the others more likely. WHEREVER YOU ARE - Home Screen and Lock Screen widgets show today at a glance - Live Activity keeps an at-risk habit on the Lock Screen - Apple Watch for a check-in from your wrist - Apple Health can complete a fitness habit when you hit the goal - iCloud keeps your other devices on the same habits TWO DAYS PRO Free includes 5 habits, widgets, Live Activity, Apple Watch, and dark, light, or system theme. Pro adds unlimited habits, lapse radar, an accountability contact, calendar-aware reminders, and the full Insights set: Year in Pixels, patterns, and health correlations. Plans and any free trial are shown in the app before you subscribe. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings. Miss one. Never two.
