Most habit apps track everything. Zuva tracks what matters: the small daily habits that research links to a longer, healthier life. BUILT ON SCIENCE, NOT WILLPOWER Zuva guides you through a 4-week protocol that introduces a few habits at a time — morning sunlight, daily movement, an earlier last meal, a consistent sleep schedule. You unlock the next week by being consistent, not by rushing ahead. After week 4, the protocol adapts to you. YOUR BIOLOGICAL AGE, FRONT AND CENTER Zuva Age estimates your biological age from your habits and Apple Health data — and shows it improving as you stay consistent. Progress you can feel, and a number you can watch move. AN AI COACH THAT KNOWS YOUR DAY Ask anything about your protocol, your sleep, your streak. The coach answers with your real data in front of it — and checks in every week with what worked and what to fix. HABITS THAT VERIFY THEMSELVES Connect Apple Health and Zuva automatically confirms your steps, workouts, sleep and mindful minutes. Less tapping, more living. WIND DOWN, NOT DOOMSCROLL Evening wind-down mode and app blocking help you protect your sleep from your phone. Your screen time drops; your sleep improves.

MicroHabit Physics See where your habits are taking you. Most habit trackers show you what you did. MicroHabit Physics helps you understand where your current habits are taking you. Track daily habits, build consistency, see what's moving you forward or holding you back, and explore how changing your routine could affect your momentum and trajectory. ### TRACK YOUR HABITS Build a daily routine around the habits that matter to you. • Log habits with a quick daily check-in • Create positive habits and habits you want to reduce • Set schedules and reminders • Track completion history and consistency • Choose from ready-made habits or create your own ### SEE YOUR MOMENTUM Your habits work together to create a pattern. MicroHabit Physics turns your tracked behavior into a simple momentum model that helps you see whether your current routine is moving forward, losing momentum, or staying steady. ### FIND WHAT'S MOVING YOU FORWARD The Forces view shows which habits contribute most to your positive momentum. See which behaviors are becoming the strongest parts of your routine and understand how consistency contributes to your progress. ### SEE WHAT'S HOLDING YOU BACK Some behaviors create friction. The Friction view highlights habits working against your positive routine, helping you identify patterns that may be slowing your progress. ### SEE YOUR TRAJECTORY Your daily actions add up. Trajectory gives you a longer-term view of your current habit pattern, helping you understand the direction your consistency is heading. Look beyond today's checkmarks and see where your current pattern could take you. ### EXPLORE WHAT-IF SCENARIOS What would happen if you changed one habit? Use What-If comparisons to explore how adding or removing a habit can affect your projected momentum and trajectory. • What if I stop a habit that's creating friction? • What if I add a new positive habit? • Which habit could make the biggest difference? Turn habit tracking into something you can explore and act on. ### UNDERSTAND YOUR PROGRESS Go beyond individual streaks. Explore analytics, habit history, momentum trends, completion patterns, insights, and weekly reviews to understand how your routine changes over time. ### BUILD A ROUTINE THAT FITS YOUR LIFE Create habits across the areas that matter to you: • Health & fitness • Focus & productivity • Reading & learning • Recovery & mindfulness • Personal routines • Breaking unwanted habits Start with your own habits or choose from the built-in habit template library. ### KEEP YOUR HABITS WITH YOU Use Home Screen and Lock Screen widgets to keep your habits and progress visible throughout your day. Set reminders to help you stay consistent. ### A DIFFERENT WAY TO LOOK AT HABITS A streak tells you how long you've continued. A completion rate tells you how often you've done something. MicroHabit Physics adds another question: Where is this pattern taking me? Track the actions. Understand the forces behind them. See your momentum. Explore your trajectory. Decide what to change next. ### KEY FEATURES • Daily habit tracking • Habit schedules and reminders • Momentum scoring • Forces and friction analysis • Projected habit trajectory • What-If comparisons • Progress analytics and trends • Habit history and consistency tracking • Personalized insights • Weekly reviews • Habit templates • Home Screen and Lock Screen widgets • iPhone and iPad support • Optional premium features • iCloud sync for supported premium features ### START SMALL.
