Have you ever been stuck in a bad situation, e.g. a bad date or boring meeting, and wanted to come up with an excuse to get out. The TIYO is just the device you need to save yourself. Just press its button, and you will get a fake phone call. You can customize who the call is coming from. When you get a call, you will have a voice on the other side telling you exactly what to say. There are a bunch of different scripts for you to choose from.
The TIYO uses Bluetooth 2.1 + EDR to work. The developers are planning to release an app for the device to make your life easier. You get 25 free calls to get started, but you can buy more. The project is on Indiegogo.
