Currency Genie helps you easily track your flying currencies using a sorted, colour-coded list to display your currency information, and by reminding you when your currencies are coming up for renewal, keeping you both safe and legal when you go flying. Designed by military aircrew, Currency Genie allows you to quickly add new currencies and update your existing ones. Simply input when you completed the currency and how long it is valid for, and its expiry date is automatically calculated; or for irregular currencies you can manually input the expiry date instead, giving you maximum control. Your currencies list is colour-coded and can be sorted 'expiring soonest', 'completed recently' or 'alphabetically', making it simple for you to prioritise what's important. Currency Genie also reminds you in advance of your currencies expiring, and again on the expiration date, ensuring you never forget to book that all important simulator trip again. There's no limit to what you can add; from medical and dental assessments, to instrument ratings and airworthiness certifications. Currency Genie: The Flying Currencies Tracker.
