Then you have indeed as described in connection with the application for the 5s (with me) iPhone (or any other arbitrary mobile phone with Bluetooth, and Android, etc.) is the perfect wireless photo or video trigger function. Once paired the phone with the app by Smart Shutter, and already you can take the mini remote, which makes a high impression, photos up to almost 10 m to manufacture mobile phone / tablet. I could simultaneously connect 2 iPhone and an iPad, on all devices, the photos are shot at the same time. The shutter lag is not noticeable. Genial! More than just a party gag, but useful tool, because mobile phone cameras are getting better interest of the quality and, above all, because you can connect several devices at the same time without any problems. The remote control comes with German manual (which is not really needed) and a plastic bracket (which you also not needed).
