Do you have a store (eg wedding dresses, shoe store, etc)? Do you have a commercial team or do you simply want to organize your photos ?.

You need iCatalog.

iCatalogo is a solution that adapts to any mobile device and allows you to create a catalog quickly and extremely easily.
You can create a catalog on a device and then share it with other devices by uploading your catalog to Google Drive and generating a QR code.

You can also backup your catalogs to have as many as you need and restore them whenever you want.

And it is an offline app, you do not need internet connection for its operation (except to upload a catalog to Drive).

And if you do not want advertising we have iCatalog, buy it
