Habit tracker that gets easier the more you repeat. Offline. No accounts.
Karv is a habit tracker built on a simple idea: every habit costs energy at first, and gets easier the more you repeat it. Spend your daily energy on the habits that matter, and watch them turn into routine. THE ENERGY SYSTEM Every habit you add costs energy from a daily battery. Add too many at once and you drain it. This forces a simple question: which habits are worth your energy today? Unlike checkbox habit trackers that let you pile on goals without consequence, Karv makes you feel the weight of each commitment. Three focused habits beat twenty forgotten ones. BUILT ON BEHAVIORAL SCIENCE Karv's energy and mastery system is grounded in how real habits work. Habits demand discipline at first, then become automatic with repetition. Karv models this cost curve. The more you repeat a habit, the less energy it costs. Hit milestones at 10, 30, 60, and 90 completions and the cost drops. Reach full mastery and the habit costs zero energy — it has become part of who you are. This means you can always add new habits. As old ones get easier, your daily battery frees up for new challenges. Your capacity grows with your consistency. PERFECT FOR • People who start strong but lose motivation after two weeks • Anyone who has tried five habit apps and found them all the same • Those who want to build a daily routine without feeling overwhelmed • People who care about progress, not just streaks • Anyone serious about self improvement and personal growth KEY FEATURES • Daily energy gauge — see your capacity at a glance • Mastery milestones — habits get cheaper as you repeat them • Streak tracking with recovery detection (one missed day does not erase weeks of work) • Statistics — completion rates, weekly patterns, long-term trends • Heatmap calendar — visualize your habits over months and years • Custom categories — organize habits by goal area • Reminders — gentle notifications, your choice of time • Works fully offline — no internet required, ever YOUR DATA STAYS PRIVATE No accounts. No cloud. No tracking. Your habit data lives on your device and nowhere else. Export anytime. Karv is built for people who want a private, offline-first approach to habit building and routine planning. FREE OR PRO Free: Build up to 3 habits with full energy, mastery, statistics, and streaks. Pro: Unlimited habits and custom categories. Start with the habits that matter most. Upgrade when you are ready. WHY KARV Most habit trackers reward you for piling on goals you never finish. Karv does the opposite: it rewards focus. By making every habit cost something, it forces you to pick what is actually worth the effort — and then quietly removes that cost as you master it. That is what carving means: repeating something until it is part of you. Download Karv and build habits that last.
