Common questions
Why is the rate different from my bank's?
RateStack shows reference market rates. Banks, bureaus, and transfer services add their own margin. To convert at the rate you actually get, add a personal rate: touch and hold a currency row, then choose Set Custom Rate.
Does RateStack work offline?
Yes. RateStack converts with the last rates it downloaded. The freshness line on the main screen shows when they were updated.
How do I change which currency I'm typing in?
Tap any currency row. It becomes the active currency, and every other row updates as you type.
What is the Parallel Market source?
An optional source with unofficial street rates for the Nigerian naira, Argentine peso, and Venezuelan bolívar. Other currencies keep official rates. Choose it in Settings > Rate Source.
How do I add a widget?
Touch and hold your Home Screen or Lock Screen, tap Edit, then Add Widget, and choose RateStack. Change what widgets show in Settings > Widgets. Widgets always convert from US dollars.
My rate alert didn't arrive.
Check that notifications are allowed for RateStack in the iPhone Settings app. Alerts are checked when rates refresh, so delivery depends on how often iOS lets RateStack refresh in the background.
How do I unlock the Gold theme?
Keep using RateStack. Gold unlocks for free after a year of use. There are no purchases in the app.
