Compound is a habit app built around one idea: the actions you take daily compound into the person you become. The goal isn't to have perfect days — it's to have more good days than bad, consistently, for a long time.
Start building — freeMost people think of habits as boxes to check. They track them for two weeks, fall off, and decide they're "not a habits person." Often the results just take longer to show up than expected.
Working on your startup for 30 minutes every day can feel small on Day 3. On Day 90, it's 45 hours of cumulative focused work — the equivalent of a full work week. On Day 365, it's 182 hours. The math only makes sense if you zoom out far enough.
Compound makes the zoom-out visible. Your streak history, sparkline, and milestone moments are all designed to make you feel the compound effect happening, even on days when it's not obvious yet.
Personalized onboarding quiz — a 2-minute quiz looks at what tends to get in the way of your habits (sprinter, ghost, perfectionist, and more) and builds a 30-day plan around your schedule.
Habit tracker — add any habit, check it daily, watch the streak grow. If you're late in the evening with unchecked habits, the app shows a gentle reminder.
Goal system — set 1–3 big goals and break them into steps. When you complete a goal's last step, the app celebrates it explicitly. Goals and habits are linked — you can see which daily habits support which long-term goals.
Daily todos — a lightweight task list that doesn't try to be a project management system. Add tasks, check them off, ask AI to plan your day.
Apex AI coach — powered by Anthropic's Claude model. Ask anything: "plan my week," "what habit should I build next," "why am I not making progress on my goal." Free for everyone.
If you're not sure what habits to track, use the built-in starter packs. Pre-built habit sets for student entrepreneurs, fitness, reading, sleep, and mental clarity. Each pack adds 3–5 habits to your tracker instantly — then you can remove the ones that don't fit.
