Vitalis

Inspiration

Sometimes I forget to drink water, Take daily steps or Check my weight. Habit tracking apps felt like chores, cold numbers with no encouragement. I wanted to build something that feels like a friendly coach, not a spreadsheet. That's why I created Vitalis.

What it does

Vitalis is an AI‑powered habit tracker that logs water, sleep, mood, steps, and weight; then gives daily tips, PDF reports, and friendly reminders to keep you consistent.

How i built it with MeDo

I started with one simple prompt: "Build 4 habit cards with +1 and reset buttons." Once that worked, I iterated: asking MeDo to add localStorage, then an AI coach with rule‑based messages, then dark mode, weight tracking, PDF reports and a tutorial. I never asked for everything at once. Each prompt was small and concrete. MeDo generated the working code every time.

Challenges i faced

The biggest challenge was scope creep, I kept wanting to add more features. I also struggled with the browser notification API; it required user permission and proper scheduling. MeDo helped me debug by explaining why notifications weren't showing. Another challenge was making the PDF export work without external libraries. MeDo generated a clean solution using html2canvas and jsPDF. Testing on mobile revealed button sizes were too small, so I asked MeDo to make them touch‑friendly.

Accomplishments that i am proud of

From zero code to a polished, AI‑powered health tracker, built entirely with MeDo prompts and finished before the deadline.

What i learned

I learned that building an app without coding is possible if you break problems into tiny pieces. I also learned that "AI" doesn't need complex machine learning; smart rule‑based logic feels just as magical to users. Most importantly, I learned that starting is the hardest part. Once I pasted that first prompt, momentum carried me.

What's next for Vitalis

We'll add optional cloud sync to keep data across devices, introduce new metrics like calories and heart rate, turn Vitalis into a mobile app, and offer personalized goal suggestions with more customizable features for a better user experience and smarter AI assistance, all while keeping user privacy and the app's simple, friendly design intact.
