About this app

Convert currency offline with saved exchange rates and your own custom rates.

Rate Keep helps you keep the bank, card, cash exchange or transfer rate you actually received. Save it as My Rate, add a useful label, and reuse it without entering the numbers again.

SAVE YOUR OWN EXCHANGE RATE
Choose a currency pair and enter the rate you received. Edit your saved rate when it changes. Keep one My Rate per currency pair, with as many supported pairs as you need.

CONVERT AND COMPARE
Calculate with your saved My Rate or downloaded reference rates. Compare one amount across multiple currencies and keep favorite pairs close at hand.

USE SAVED RATES OFFLINE
Your manually entered rates work without a connection. Reference rates stay available offline after an initial download. Connect to refresh them and check their update time.

KEEP RECENT CALCULATIONS
Return to your last 50 conversions, repeat a calculation, or share a result with its rate source.

TRY EVERY FEATURE FOR 7 DAYS
Start your free trial when you are ready. After 7 days, a one-time lifetime purchase is required to continue using the app. No subscription, no automatic renewal and no automatic charge when the trial ends. Your local store price is shown before purchase. Existing paid access is honored, and purchases can be restored.

No app account is required. No ads.

Reference rates are estimates. Your bank or transfer provider may use a different rate or add fees. Rate Keep calculates amounts; it does not exchange money or make transfers.
