Karv - Build Habits That Last

EVERY HABIT COSTS ENERGY. SPEND IT ON WHAT MATTERS.

Karv helps you build habits that stick by showing you the real cost of each one. Start with a daily energy battery, choose the habits worth your effort, and watch them get easier as you carve them into your routine.

THE ENERGY SYSTEM

Every habit you add costs energy from your 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 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 SCIENCE

Karv's energy and mastery system is grounded in behavioral science. Real habits follow a cost curve — they demand discipline at first, then become automatic with repetition. Karv models this.

The more you repeat a habit, the less energy it costs. Hit milestones and the cost drops. Reach full mastery and the habit costs zero energy — it has become part of who you are. Just like real life: discipline becomes routine.

This means you can always add new habits. As old ones get easier, your battery frees up for new challenges. Your capacity grows with your consistency.
