Currency Genie is a comprehensive tool designed to assist users in easily tracking their flying currencies. Developed by Mountain Wave Media Ltd, this iPhone application offers a sorted, color-coded list for displaying currency information. It serves as a reminder for upcoming currency renewals, aiding users in staying compliant and secure during their flights.

Created by military aircrew, Currency Genie enables users to efficiently add new currencies and update existing ones. By inputting completion dates and validity periods, the app automatically calculates expiry dates. For irregular currencies, manual input options are available for maximum control. The color-coded and sortable currencies list allows for easy prioritization based on criteria like 'expiring soonest' or 'completed recently'.

Additionally, Currency Genie provides timely reminders for impending currency expirations, ensuring users never miss essential simulator trips. The application accommodates a wide range of additions, from medical assessments to airworthiness certifications, making it a versatile flying currencies tracker.
