The Morning vs Evening Habit Tracker: What the Data Actually Shows

Most habit apps do not care WHEN you complete a habit. HabitStock does -- and it changes everything. The Setup HabitStock visualizes habits as a stock price chart. Every completion drives the price up. Every miss causes decay. But unlike other apps, the price algorithm accounts for when you complete, not just whether you did. Here is the core timing logic: function calculatePriceImpact(completionTimestamp, habitConfig) { const hour = new Date(completionTimestamp).getHours(); const isPreferred = isWithinPreferredWindow(hour, habitConfig.preferredTime); // Morning completions in preferred window get full credit // Evening catch-ups still count -- but with a 15% weight reduction const timingMultiplier = isPreferred ? 1.0 : 0.85; return BASE_COMPLETION_VALUE * timingMultiplier; } function isWithinPreferredWindow(hour, preferredTime) { const window = 2; // 2-hour buffer return Math.abs(hour - preferredTime) <= window; } This is not punishment -- a 15% reduction still rewards completion.
