One of the intriguing aspects of iMessage sticker packs is that they can be as simple as static images or as complex as full-blown apps. There’s a place for both, but it’s interesting to see innovation beginning to take shape as a differentiator among sticker sellers.

Health Stickers, by Krishna Kumar, is a good example. It lets you share your exercise and health accomplishments via stickers, whether that’s your step count, weight, heart rate, or something else. What’s cool about the app is that it pulls health data from Apple’s Health app with your permission. Share you step count with a friend in Messages and the sticker includes your current step count total. The stickers cannot update dynamically, but you can always resend a sticker to a recipient if you want to update your statistics. The step count in particular seemed high compared to Pedometer++, but for casual sharing, as opposed to precise measurement, the app has a lot going for it.

Health Stickers is available on the iMessage App Store as a free download.
