"What's My Age Again" is a utility app developed by Josh Holtz for iPhone users. It offers a simple and efficient way to remember your age and the ages of your loved ones. The app provides widgets for quick access to age information right on your Home Screen or Widget Sidebar. Users can customize the background and text colors of the widgets to suit their preferences.

The app includes a widget for your own age, allowing easy age tracking, and another widget for tracking the ages of others, such as children, parents, grandparents, and significant others. Users can even display weeks and months for children on the widget. Additionally, the app allows users to optionally show birthdays on the widgets, adding a personal touch to the age tracking experience.
