AURA Devices has announced the launch of Aura Strap 2, an Apple Watch strap that augments the smartwatch’s fitness and health capabilities with several features.

Aura Strap 2 follows its predecessor and adds notable functions, including body measurement changes for water balance, muscle and fat after a period of exercise. It’s 20% slimmer and 5% narrower to provide a better fit for Apple Watch users. Additionally, the strap has built-in wrist sensors that can read bioelectrical signals and interpret them through the AURA app.
AURA says that the updated design allows single-touch measurements and 16x more data point collection. The metrics are read and the user is given goals and recommendations for optimizing their fitness performances.
The company also announced a new subscription plan- AURA Plus offers monthly nutritional and fitness reports, as well as deeper analysis of fitness content, body composition and more. AURA 2 buyers will get it free for 6 months and get charged $9.99 monthly after that.
