Sennaby
Read full descriptionHide full description
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.
