Can I see what my Shopify app would look like before committing?

Yes. TicApp's builder lets you assemble a working sketch — your logo, your colours, your home screen, your category and product screens — from sections taken out of apps already published. It costs nothing and installs nothing.

Every section in it is cut from an app on the App Store today, so nothing you assemble is a sketch somebody would then have to work out how to make.

It never connects to your store. No API access is requested, no products are imported and no images are taken from your site.
