How to Take A Picture Without Pressing The Button?

I have an iPhone 5s. On Facebook I see pictures where it's not a "selfie" and I know nobody took it for them. Is there a free app that can take a picture for me? Please help I have new outfits and I want to take pictures and nobody will take pictures for me. Lol so help?!

There's many apps that can time your photos. For example you can set your phone up wherever you want and it will count down from 10 then when the countdown is done it will take the picture. Just search "timer camera" in the app store. Most of them are free.

Timercam is the one i have, its in the appstore
