Discover what makes the Heir different
The Heir instantly adds smartwatch features without changing how your watch looks. It tracks your activity: including steps, calories, activity classificaiton, active distance and time - and syncs that data to Apple Health (iOS) or Health Connect (Android). The Heir also provides call and text notifications through haptic vibrations.
No. The Heir does not use magnets and doesn't require tools or modifications. It attaches using microsuction technology - thousands of tiny air pockets that create a secure hold without damage. It is strong enough to stay in place during daily wear, but flexible enough to remove and swap between watches countless times.
The Heir is designed to work with most modern watches with a flat or slightly curved caseback (ideal for watches greater than 34mm wide). It does not require any modification to your watch. If your watch has heavy engravings or a highly textured caseback, results may vary with suction. If your watch is modern (was built after the 80s), it’s built to withstand significantly more impact than anything the Heir produces.
No. The Heir is a one-time purchase. All core features and ongoing software enhancements are included in purchase. There is no subscription required.
Future hardware upgrades may require a separate purchase, but your Heir works out of the box with everything included.
The Heir lasts up to 42 hours on a full charge. Included in your purchase is a USB-C charging dock and it takes about 1 hour to fully recharge.
