Metafields Guru

Guys, I will be honest here, I had tried many apps for Metafields so far this is the best app you can get right now, also the support is so awesome they are ready to help you and they answer so fast, I am so satisfied with that app, it's so sad that I can give only 5 stars because this deserves more and it's totally free!

I use this app to generate all information about the products with JSON including picture video and all information, it's easy to update the template anytime I like for all products, also the user interface is so simple and easy to understand.
