HealthMon is a virtual pet and step tracker app that combines fitness goals with caring for a virtual pet. The premise is simple: feed your pet as you walk more each day. By meeting your daily and weekly step goals, your pet grows with you. However, failing to meet these goals can lead to your pet falling ill or worse.

The app offers features like automatic syncing with Apple's Health App to track your steps accurately, the ability to feed your pet fruits and play with it to reach your daily goal, and multiplayer functionality to engage with friends. HealthMon also supports Apple Watch integration for real-time updates on your pet's status and syncs seamlessly between your phone and watch. Additionally, third-party step tracker integrations like Fitbit and Jawbone are supported, and the app provides a range of pet animations for use in iMessage stickers.
