Meet the Defender: a self-defense tool that helps you stay out of trouble. The Defender has a pepper spray to subdue attackers. It also has a camera that lets you capture a photo of them. The device also has a flashing light and audible alarm to attract attention. The Defender works with iOS and Android devices. It does have a subscription service, but you get 12 months of it for free.
The Defender lets you take a photo of attackers and send them to lawn enforcement officials. It is also useful to have in case of a medical emergency. You can support the project on Indiegogo.
