How the habit tracker keeps you consistent
Consistency, not perfection, is what turns a behavior into a habit. The tracker leans on the “don't break the chain” principle: a rolling five-week calendar makes your streak visible, so each completed day adds momentum you won't want to lose. Missing a single day rarely breaks a habit — the science says two consecutive misses is the real risk — which is why streak shields exist. Bank one for every seven completions and spend it on a missed day to keep your chain intact through a sick day or a trip.
Streaks, shields, and completion rate explained
Three numbers on every habit card tell you what's happening: your current streak (consecutive days right now), your best streak (the longest chain you've ever built), and your 30-day completion rate (the share of the last month you actually showed up). The rate is the honest one — a streak can hide the days you skip, but a 70% rate tells you there's room to tighten up.
