There are some tools that enable people to build apps without actually having to code. So this is auto-promotion, but Bubble (https://bubble.is) is one of them (I’m a cofounder). You can build your product without code on Bubble. There is a learning curve, as it’s programming, but this is with a visual interface that gets rid of the coding aspect. Our users have build crowdfunding platforms, marketplaces, all starting from a white page (no template) and without code.
You're welcome. Let me know if i can help with anything.
