SlimHabitsOS

A habit-first weight loss planner in one private offline app. Seven tabs. One file. Yours forever for one price. This is NOT a calorie counter. There are no macros to weigh, no food databases to scan, no points to budget, no fasting windows to police. The whole engine is consistency on simple daily habits, because the people who actually lose 10-50 pounds and keep it off do not out-track their dinner - they repeat the same boring 7 things until the scale moves on its own. Seven default habits ship preloaded: drink 80 oz of water, walk 8000 steps, eat protein at every meal, no eating after 8pm, sleep 7 plus hours, walk after dinner, eat vegetables 3 times a day. Add up to 15 custom habits of your own. Every habit gets a color-coded adherence bar over the last 7 and 30 days, so you see at a glance which one is the weak link this week. A weight tab logs daily weigh-ins, draws a smoothed trend line through the noise, and runs a linear-regression projection that estimates your goal-date based on your actual trajectory - not a fantasy calorie deficit. A body measurements tab tracks waist, hips, chest, arms, and thighs with running deltas, because the scale lies during recomp and inches do not. Habit stacks let you chain 3-step micro-habits (e.g. coffee triggers vitamins triggers 5-minute stretch) so new behaviors anchor onto existing ones. A day-of-week skip-pattern detector flags which day you are quietly losing the war on (most people: Friday). A units toggle handles lb / kg and in / cm. A daily note textarea catches mood, sleep quality, soreness. A recent wins chip strip shows your last 7 successful check-ins for momentum. Keyboard shortcuts 1 through 7 toggle today's habits with one keystroke. Settings include profile, goal weight, JSON export and import, demo seed (14 days of sample data), and a double-confirm hard reset. Every input saves locally to your device. Nothing goes to a server. No account, no subscription, no app store, no annual fee, no health data sold to advertisers. Works on laptop in any browser, and adds to your iPhone or Android home screen as a standalone app for offline use.
