Does what it is supposed, software a bit annoying

I bought the Smart Hutter to easier to shoot photos with my iPhone. Together with a tripod can achieve steady images at high quality.
The product is working properly after setting, even if now and then a double-pressing is necessary. The supplied cord has a jack connection with which he fits perfectly into the iPhone. However, the provision of which is a nerve-wracking task. I have several minutes and tests used with pliers and cable ties as a guide until the whole system finally operated.

The only thing that strikes me is the negative product the necessary app. Apart from the fact that there is an additional program and thus a potential data leak on my iPhone, the operation of the app feels very bumpy and slow. To turn the camera direction Alone takes time no less than 5 seconds to time to mention the change of photo video altogether. Here is definitely still room for improvement visible.

Otherwise, there is nothing to complain about and the product works as it should. 4 stars.
