FX Sentinel (the “App”) is for foreign currency speculators.
This app monitors the Foreign Exchange for IQD, VND and IDR against the USD and displays current and historical FOREX data regarding those currencies.
It does not provide for exchanging or purchasing those currencies.
When you purchase a subscription, you are given access to real-time rates.
The app also provides you with three levels of notification for changes in the rates so that you are only notified (even when the app isn't running) when the criteria set is met.
Annual Subscription is $49.99 and Monthly Subscription is $4.99.
