Lumafit, launching later this year, is an ear-worn fitness tracker that also checks continuous heart rate. Its Kickstarter pre-order price is $99.
The two-part device has a motion-sensing accelerometer, and also a clip that reads heart rate through the earlobe.
It lasts six hours on a charge, and pairs with Android and iOS device.
A stress-reducing app focuses on breathing exercises to control heart rate, using continuous readings as a form of feedback.
The fitness app aims to work with exercises that don't normally work with wrist-worn fitness bands.
