Look: There’s no platform that can enable someone with no freaking clue about how to build an app to magically build one... But boy does Bubble come close.
I love visual/no-code/alterna-code environments and have worked on several of the most famous ones. Bubble is right up there.
I feel like this tool‘s positioning (“you don’t have to be a coder”) belies its true strength. It‘s GRRRREAAAT for those who would rather NOT code most stuff.
I do my best to help folks out in the forums at forum.bubble.is, but wish it had a StackExhange equivalent -- it’s that deep. Love it and wish it the best. You can build awesome stuff on Bubble, but (duh) prepare to learn some computer science In the process (this is a GOOD thing)...
An app that's more about doing something technically than paying any attention to the user or use-cases. Is just very impractical, with all the real-world features difficult to impossible. Just look at data-upload: https://forum.bubble.is/t/best-way-to-bulk-upload/1690
When you're building a new products, user feedback is critical. You can gather feedback in a variety of ways, through in-person customer development interviews, surveys, and by simply looking at the data. I'm particularly fond of doing user testing (UserTesting is an awesome tool for this) although its only a "simulation" of what your users are actually doing.
FullStory captures a screen recording of your site visitor's actions and behavior within (cue Steve Irwin impression) their natural environment. We've used it many times at Product Hunt to better understand how people are using new or beta features we're building. It's 👍🏼.
