About
Standing at a market stall abroad, no signal, no data plan — and you need to know right now whether 45,000 is a bargain or a rip-off. CurrencyOff answers in one glance: a currency converter that works entirely offline, with nothing to sign up for and nothing sent anywhere.
Most converter apps quietly stop working the moment your connection drops — exactly when you need them most. CurrencyOff ships with a full reference rate table inside the app, converts 25 currencies with precise decimal math (no floating-point rounding drift), and labels every rate with the date it was taken, so you always know exactly what you are looking at. Indicative rates, honestly dated — ideal for sizing up prices, tips and cash exchanges on the spot.
WHAT YOU GET
• An answer before the shopkeeper finishes the sentence — type 45,000 and see your home currency instantly, even in airplane mode
• 25 currencies covering the places people actually travel: EUR, JPY, THB, VND, MXN, AED, TRY and more
• A quick-reference strip showing what 1, 5, 10, 50 and 100 of the local money is worth — ready before you open your wallet
• Pinned pairs, so this trip's EUR to USD is one tap away every time the app opens
• Saved history with the as-of date on every entry, so you can check later what that dinner really cost
• A full rate board — what 1 unit of your money buys across every other currency at once, with fixed-peg and high-volatility flags
PERFECT FOR
• Travelers landing without a local SIM or data plan
• Cruise passengers and hikers who spend days with zero coverage
• Cash-market hagglers who need a number mid-negotiation
• Anyone tired of converter apps demanding accounts and connections
PRIVATE BY DEFAULT
CurrencyOff makes zero network requests. No account, no tracking, no analytics, no ads. What you convert stays on your phone — full stop.
FULL ACCESS
CurrencyOff Pro unlocks the complete 25-currency board, unlimited saved history, unlimited pinned pairs, and any currency as the base of the rate board. Choose a weekly or yearly subscription, or a one-time lifetime purchase.
Download CurrencyOff before you board — it will be the one app that still works when you land.
Weekly and Yearly are auto-renewing subscriptions: each renews at the end of its period unless auto-renew is switched off at least 24 hours beforehand, and both can be managed or cancelled at any time in your Apple Account settings. Lifetime is a one-time purchase and never renews.
