RateRadar

Should I exchange money today? RateRadar watches FX rates and tells you when the timing actually beats your 90-day baseline. Whether you're planning a Japan trip, paying overseas tuition, or remitting to family, RateRadar gives you the one signal nobody else does for free: a daily Should-I-Exchange-Today verdict against your own custom baseline, with the 30/90/365-day percentile so you know if today is a 1-in-20 day or a 1-in-2 day. ✓ **"Should I exchange today?" daily verdict** — Yes / Wait / Now with a one-sentence reason ✓ **30/90/365-day percentile** for any currency pair — is today rare or normal? ✓ **Multi-currency dashboard** — HKD, USD, JPY, EUR, GBP, CNY, KRW, THB, AUD, SGD ✓ **Custom baseline** — set "I want JPY when it crosses 5.4 per HKD" and get notified ✓ **Trip planning mode** — plan a $5,000 Japan budget in HKD at today's vs target rate ✓ **Remittance mode** — model monthly transfer at the average of next-N days ✓ **Pure FX, no fee theatre** — we surface the mid-market rate; you compare against your bank's spread ✓ **Bilingual EN/繁中** — designed in Hong Kong for HK + international users ✓ **Offline graphs** — historical chart works without a connection after first sync ✓ **No tracking, no remittance partner kickbacks** **Your currency intent stays private.** RateRadar fetches public mid-market rates (no personal data sent) and runs the comparison on your phone. We never see which currencies you watch, which alerts you set, or how much you plan to exchange. **Built for:** HK residents planning Japan / Korea / Taiwan trips wondering if today is a good buy. Overseas students' parents remitting tuition and deciding "this month or next?". Expat workers paid in one currency, spending in another. Anyone who's clicked through XE.com banner ads to a partner-bank quote and wanted a clean alternative. **Why an offline FX rate app matters:** every "FX comparison" site monetises your travel + remittance intent through partner kickbacks. We don't have a partner. We don't have an affiliate link. We just show you whether today is unusually good. Download free now — know if today's the day to exchange.
