Focus that pays. Set a goal, pick an inspirational scene, stay in deep work — and watch the key turn. Every finished session unlocks a real reward: money saved, time banked.

A key that becomes a check: effort unlocking reward. The symbol lives in a soft blue tile; the wordmark stays lowercase and quiet — the app should feel like a calm companion, not a coach.
Most focus apps feel like punishment — timers, streaks, guilt. Northline flips it: focus is an investment. You set a goal that matters to you, choose a scene that calms you, and while you work, the app quietly turns minutes into progress. Finish the session and the key turns — the reward unlocks. Money towards the thing you're saving for, or simply time you genuinely owned.
Four steps, no friction. The whole loop is designed to feel like a small ritual, not a chore.
Soft 3D, calm blues, one decision per screen. The goal page doubles as the scene picker — motivation on the left, atmosphere on the right.
Each scene is a slow, looping world — built to lower your heart rate, not raise it. The solar eclipse scene is the signature: totality arrives exactly when the timer ends.
Northline is a concept project. It is designed to help people finish more sessions and treat focus like saving, with the key-unlock moment built to be the screenshot people share. (Concept work, no real user data.)
