Meet the WiKey: a smart device that sits on your key chain and lets you store files, monitor your health, and control your smart devices. It can be used to store up to 128 GB of files in an encrypted fashion. The device tracks your daily walking activity and calorie consumption and works with Google Fit and Apple Health. It also notifies you when you have new notifications. You can use the companion app to set up custom alerts.
The WiKey is waterproof and shock resistant. It can alert you when you are about to leave your phone behind. If you lose it, you can use the app or the community to locate your device. The WiKey will be compatible with iOS/Android devices. It is getting funded on Indiegogo right now.
