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.

LogBook
Read full descriptionHide full description
LogBook is a habit tracker with a diary attached. You tick what you kept, then you write the day down. Months later the streak tells you what you did, and the page tells you why. WHAT IT DOES • One check-in a day. At a time you choose, LogBook asks. Tick the habits you kept, add a photo, write a line or a paragraph. Two minutes, once. • A streak you can see. Tally marks, not a number in a badge. Every habit keeps a grid of its own — a month, or a year, at a glance. • Pages you can reread. Every check-in becomes a dated page in the log. Scroll back through it like a notebook, because that is what it is. • Habits you build, habits you quit. Track the run you want to start and the scroll you want to stop, side by side. • A home-screen widget. Your grid, on the home screen, without opening anything. • Share the day, or don't. Post a day to a small feed of people you trust and react to theirs. Off by default. Nothing is public, and there is no follower count. • Dark mode that was actually designed. Same paper, dimmed — not an inverted screenshot. • Works offline. Everything is written on the phone first and synced when there is a signal. Aeroplane, tube, cabin in the woods: the check-in still happens. WHAT IT DOESN'T DO No streaks-as-guilt. No push notifications begging you back. No leaderboard, no points, no streak insurance to buy. Miss a day and the ledger just says so — you can tick it late if you actually did it. THE FREE LOGBOOK Three habits, kept forever, with the full check-in, the full journal, the widget and the feed. No trial timer on the basics. THE FULL LOGBOOK Unlimited habits and every page kept for good. • $2.99 a month, or $19.99 a year (7 days free on both) • $29.99 once, if you would rather not subscribe Subscriptions renew until cancelled; manage them in your App Store settings. Cancel any time during the trial and you are not charged. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ WHO IT IS FOR People who have tried a habit app, hit day forty, and found nothing to look back on. LogBook is built so the looking back is the point.

Verdict
The clearest difference is ads: LogBook at none against MicroHabit Physics's shown. LogBook also leads on iOS requirement (15.1 vs 18.0). On price, in-app purchases and device support there is nothing between them.
