Zenith Flex is a mobile application designed for iPhone users to facilitate the management of consumer-driven healthcare and other tax-favored benefit accounts. This free app serves as a centralized platform where participants can easily access their benefit health account balances, transaction histories, and demographic details.

The application enhances user experience with features such as email alerts, contact options for administrators, and strong authentication methods. Users can log in using the same credentials as the ZenithFlex Portal, eliminating the need for additional registration. Additional functionalities include viewing dependent information, card details, and PINs, as well as the ability to register new users directly from the mobile device.
