I mostly like the drag-and-drop builder, push notifications, AdMob Integration, and nice template library. But the other features like easy integration with WooCommerce and WordPress are fantastic too.
I like the following features of the Stack
1. User Interface
2. Drag and Design
3. No code involved
4. Inbuilt payment methods
5. Customizable menus
6. Chat & Form integration
7. Audio & Video player integration
8. Google Maps integration
I got the stacks membership from the app sumo deal and I really like how easy to use the interface is. It's well-designed and I can make an app to sell on Google Play to monetize and make some extra money without having to code. I also am a small business owner and the app builder can be useful for selling a product if my business were to enter that area. I did CS in college and there are a ton of ways to make money on the internet by monetizing blogs and apps and this makes it easy without having to code, which saves a lot of time.
