Most trackers want your bank login, then convert everything at a rate they picked. All My Money is the opposite: type what you hold in each currency once and it keeps one total in your home currency, revalued at mid-market rates every time you open it. You also get each currency's share of that total, a year of history rebuilt from stored daily rates, and a one-tap blur for when someone is looking over your shoulder. Free, no account, no bank linking. Balances stay in your browser.
Free multi-currency converter: add USD, EUR, JPY and 140+ currencies into one total at live mid-market rates. 62 pair pages with daily history back to 1971, year and month archives, a calendar-month seasonality table, CSV export, an embeddable rate card and an API. No sign-up.
