Human OS

YOUR BODY HAS A BATTERY. DON'T LET IT DIE. We take better care of our phones and digital pets than we do of ourselves. Human OS changes that. It visualizes your fundamental needs - Food, Water, Rest, and Social Connection - as simple, decaying energy bars. If it’s not on the screen, it doesn’t exist. Human OS puts your physical state right on your Home Screen with beautiful widgets, giving you the "object permanence" you need to stop ignoring your body. WHY HUMAN OS? Most health apps want you to be a data scientist. They ask for calories, milliliters, and sleep cycles. Human OS just asks: “How do you feel?” FEATURES: - 4 Core Vitals Track Fuel, Hydration, Battery (Rest), and Connection. Watch them slowly deplete over time, just like a classic digital pet. - Intuitive Sliders No tedious data entry. Just slide the bar to match your feeling. Tap for a quick boost, or slide for precision. - Smart Morning Reset Bad days happen. Human OS forgives you. Every morning between 6-10 AM, your vitals automatically reset (Battery to 100%, Fuel to 50%) so you never wake up to a screen full of red warnings. - Home Screen Widgets Keep your vitals visible at all times. If you have ADHD or get hyper-focused, the widget is your gentle nudge to drink water or take a break. - 100% Private & Offline Your health data is yours. Human OS runs entirely on your device. No cloud, no tracking, no ads. WHO IS THIS FOR? - ADHD Brains: Who forget to eat or drink until they crash. - Creators & Devs: Who get lost in "flow state" for hours. - Burnout Prone: Who need a visual signal to slow down. PRICING Human OS is a one-time purchase for lifetime access. No subscriptions. Ever. Stop running on empty. Install Human OS and keep your character alive.

Verdict

The call

The clearest difference is in-app purchases: Re at none against Human OS's 1. Re also leads on iOS requirement (13.0 vs 16.0). On price, ads and device support there is nothing between them.
