Marginal.

Marginal is a daily codex for people playing the long game. It's a simple, focused space to track the small gains that compound over time - habits, discipline, and consistency, logged day by day. No leaderboard. No showing off. No endless notifications. Just a clean daily record you actually return to. WHAT YOU CAN DO - Log each day as an entry in your codex - Build and hold streaks across the habits that matter - Keep a private, distraction-free record of your progress - Focus on the marginal gains that add up over months, not minutes Marginal is built to be opened, used, and closed, a tool, not a time sink. Accounts and cross-device sync are on the way for everyone on the early-access list. For the long game.
