Your numbers. Your browser.
A private dashboard for the markets you follow. Add an instrument, log its price whenever you check it, and see changes, sparklines, and a chart. There are no live feeds, no accounts, and no tracking — data is saved only in this browser.
How it works
- Add an instrument with a symbol, a name, and an optional group.
- Log a price with a date. One price per day; logging again replaces it.
- Change is measured from the previous logged price.
- Export to JSON to back up or move to another device; export CSV for spreadsheets.
