Creating A Client "mobile Gallery App" Similar To Pixieset

Has anyone used Sytist to create a "App" that clients can purchase and add to their smartphone? I was researching options and came across Pixieset's Mobile Gallery App and a few other offerings out there. But, Sytist can easily do this! Is anyone already doing this?

I plan on playing around with it to find the best gallery configuration to use. 

Ithink this would potentially make a fantastic Sytist enhancement if there was a way to automate the setup process after purchasing a digital Buy All option.

I have been thinking about doing this too.  My plan is create a section to hold the apps, then create a template in page designer to use over and over quickly.  I currently use something else but want to bring everything into sytist.  From experience building in the app maker i have, i reccomand small image files and 20 or less to keep it moving fast.

Any webpage can be saved on an iPhone home screen as an icon.
