Ratewind — currency, made beautiful and useful. No ads. No tracking. No account. One purchase unlocks everything, forever. What you get ・153 currencies. Convert several at once — drag to reorder, tap to switch the base ・Travel mode: a price cheat sheet for where you are, and a tip calculator ・Point the camera at a price tag or a receipt and it reads the amount — all on your device, nothing is uploaded ・Charts from today back to 1999 (1D / 1W / 1M / 3M / 1Y / 5Y), with any number of currencies overlaid. 1D is plotted hour by hour, so you can see today's move ・Rate alerts that notify you when your target is hit ・Three home screen widgets ・5 colour palettes × 3 designs × 7 app icons ・Works offline with the rates it already has About rate updates (please read) Rates refresh every hour — all 153 of them. The long-range history in the chart (before 2021) comes from the official reference rates published by the European Central Bank (ECB), which the ECB itself issues once each weekday. On weekends and public holidays the FX market is closed, so rates barely move. These are not live trading rates, and they are reference rates that differ from what banks or exchange counters actually offer. Please check with your financial institution before acting on them. About Pro (one-time purchase) A single purchase unlocks everything. It is not a subscription. If real-time updates are offered in future, they may be a separate option, since live market data carries a monthly cost. Long-term history: European Central Bank (ECB).
