I as non-coder built and deployed an app with only "vibe-coding" using firebase studio

So, I don't know how to code and I built my first MVP. My last coding experience was in 2014, when I applied for IT major in university. Even then I knew only basics of pascal. I know how code works like in general, but nothing more.

Some time ago I spontaneously had this idea to build an app which will help people to make new good habits and get rid of bad ones. I checked the prices for an app and couldn't believe my eyes. It was like 10k $ for just 1-3 pages or something like this. So I had to put it on the back burner.

But then firebase studio appeared. In 2 months of very lazy "vibe-coding" (one week of pure development at most) I built and deployed my web-app MVP (front-end, back-end all in firebase). Then I asked chat-GPT: where do I share my app and where do I get feedback? And it directed me here.

What my app has now:

• register with e-mail (I wanted to add registration with just login, but didn't found out how yet)

• creating habits with tasks to follow, choosing period of time and particular days in that period

• function to ask AI assistant to fill habit creation form for you (needs manual check after)

• tracking overall progress of habit (by % of completed tasks) and daily progress (by heat-map)

• habit archive (ended habits go there)

• calendar with daily routine (you can see all the tasks of all habits for particular day)

• friends feature with chat (you can find and add friends by searching for their exact e-mail address)

• premium account (for now just for tests, only influences quantity of active habits you allowed to have)

• AI assistant (not much functionality, just for tests)

• feedback system - button in top right corner

So now, I want people to try out what I've built give me a feedback. What you think about the app? What bugs you've encountered? How is the experience overall? If you want to help me, here is the link:

https://habitual-2uuv1.web.app/

And some useful info:

• notifications don't work

• you can register with non-existent e-mail - just type any, it will not send you confirmation e-mail

• you can change to premium account by just choosing it in your profile page (existing limitation are for testing purposes and to prevent database abuse)

• all images are placeholders for now

• AI-assistant don't have access to your info (may change in future)

• you can get all 3 existing achievements just by 1 task (create a new habit, choose only one active day, check all tasks and that's it)

• feedback button is in top right corner

Known issues:

• calendar button doesn't work for non-logged in users

Thank you for your attention and help!
