Karv - Build Habits That Last

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.

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.
