Meet the Ollinfit: a smart wearable device uses 3 sensors to improve your performance as you exercise. It detects your mistakes and corrects you using real-time audio and vibration feedback. Its 3 sensors capture your full body motion while the companion app analyzes the data in real-time to guide you.
Ollinfit gently vibrates to help you correct your improper form. The device is shockproof and sweat-proof. It has a rechargeable battery that lasts up to 14 days. The companion app lets you analyze your performance and learn how to workout better. Yet another interesting Kickstarter project.
