Unfortunately, not an app. However, our website www.encyro.com is pretty mobile friendly. For instance, if you open it on your iPhone, it will let you take a picture and attach directly. Also, you can forward files received within a message securely to others without first downloading to your phone. For more details see: https://help.encyro.com/section/7-mobile-uploads-photo-scan
You can install the website as an app icon to your iPhone, so its easy for you to open: from there on, it will still be a website, but you would start it like an app. Here is how: open www.encyro.com on your iPhone (in iOS Safari) and in the bottom bar click the icon that looks like an arrow coming out of a square (the "share" icon).Now click "Add to Home Screen" (this would be a gray square with a plus sign, like in the second row of options shown for sharing). Clcik Add on the next screen. You will get an icon with an "E" - it will look like an app but when you tap it, it will open the Encyro website.
