Sennaby
Read full descriptionHide full description
Stocks have prices. None of those numbers are about you. Sennaby turns your transactions across brokers and markets back into a complete record — and then answers the questions that record holds about you: where your cost basis actually sits, where your money actually is, and what your decisions over the years added on top of doing nothing at all. You'll see: • Your own asset curve, and the gap that gradually forms between it and the market • Real cost, profit and loss, dividends, fees and taxes, reconstructed from every transaction • How you trade: win rate, average holding period, the rhythm of your entries and exits • What your allocation and holdings actually look like, without watching quotes all day • Short-Term, Long-Term, Dollar-Cost Averaging, Dividend Income — four templates, four ways to look at yourself Sennaby isn't a market-watching app. It's built to help you understand your own investing a little better than yesterday.

Verdict
The clearest difference is in-app purchases: TraderMemos at none against Sennaby's 4. TraderMemos also leads on iOS requirement (16.4 vs 18.0). On price, update cadence, ads and device support there is nothing between them.
