Stocks have prices. None of those numbers are about you. Sennaby is your stock journal. Taiwan stocks, US stocks and funds all go in, with exchange rates handled for you — and the moment your broker app shows a fill, take a screenshot and it's logged. Once it's all down, Sennaby answers the questions about you: where your cost basis actually sits, where your money actually is, and what your decisions over the years added on top of just sitting still. You'll see: • Everything you own the moment you open the app — Taiwan stocks, US stocks and funds, side by side • Real cost, profit and loss, dividends, fees and taxes, worked out from every transaction • When your next dividend lands, and how much it'll be • Your own asset curve, and how far it sits from the market • How you trade: win rate, average holding period, the rhythm of your entries and exits • A Home Screen widget, so you know today's gain without opening the app • Short-Term, Long-Term Growth, Dollar-Cost Averaging, Dividend Income — four boards, four ways to look at yourself • Automatic iCloud backup, so nothing goes missing the day you switch phones Sennaby isn't a market-watching app. It's built to help you understand your own investing a little better than yesterday.
