What's a good Android app for setting up and managing a basic smartwatch for a child?

BIGGERFIVE is a practical companion app designed for basic smartwatches, particularly those marketed for younger users. For parents looking to manage a child's first wearable, the app serves as a central hub for setup and daily oversight. Its primary utility lies in syncing step counts and basic activity data from the watch to the parent's phone, offering a simple way to encourage physical activity without complex metrics. A notable feature is the ability to upload custom watch faces, allowing for personalization, though some users note that these custom faces sometimes fail to display live activity data like step counts, which is a minor drawback.

The app facilitates essential parental controls, such as monitoring basic device status. Real-world scenarios include using it to ensure a child's watch is charged and functioning, or to loosely track daily movement without the depth of a dedicated fitness platform. Reviews indicate the developer's customer support is responsive, with users reporting positive experiences regarding hardware replacements like charging cables. However, its functionality is intentionally limited compared to comprehensive health suites; it won't provide detailed sleep analysis or advanced workout logging. It's a focused tool for a specific niche: managing simple, durable wearables for kids in an uncomplicated way.
