Life K-Line turns a traditional BaZi birth chart into a stock-style candlestick chart spanning ages 1 to 100, with AI-written readings for each life period. Enter a birth time and place and the app casts the chart automatically, correcting clock time to true solar time from longitude and computing major luck cycles and annual cycles for you. The main chart draws open, high, low, and close values for every year on dual tracks, so strong and weak periods read at a glance like bull and bear markets. Request a deep analysis and the AI writes up personality traits and talents, career and wealth trends, relationship outlook, health reminders, and favorable directions. A Web3 section covers crypto trading fortune, likely windfall years, trading style suggestions, and industry fit for digital asset enthusiasts. Browse the celebrity case library to see the life charts of well-known people and compare them against your own pattern. The dashboard view shows today's fortune summary, and the knowledge hall teaches the BaZi concepts behind the charts at your own pace. Hosting it yourself keeps birth data on your server, and the app calls the OpenAI-compatible model endpoint you configure with your own key. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.
