CLUSTER EXCHANGE-RATES-CURRENCY · 85 ENTRIES · EARLIEST ENTRY 2016-12-12

Currency conversion web apps

This cluster consists of web apps, calculators, and utilities that convert amounts between currencies using exchange rates, with some also tracking rates, computing fees, or handling crypto/fiat conversions. Dated entries appear sporadically from 2018-10 through 2026-02 with no consistent monthly pattern, and many members lack source dates. On traction, currencieconv.com leads with 1 star, while other identified members have 0 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
