ChartLogs

How much would your money have grown if you had invested in the past?
ChartLogs is a simulation app that lets you explore the last 10 years of price performance for stocks, ETFs, crypto, FX, and commodities.

For example:
“If I had invested ¥1,000,000 in Bitcoin and the S&P 500 five years ago, which one would have grown more? What if dividends were included?”
ChartLogs helps you compare results intuitively with graphs.
