First, big shout out to the V0 team for making this tool. Has helped me solve a personal pain point in a fun and engaging way!
Context:
After a recent trip, I felt off and swelled up on my left leg!
The culprit? Sodium overload + not enough water.
But no app I found could help me hydrate dynamically—based on what I drink, eat, or need.
So I Vibe coded Sip Pal, the FIRST 
AI hydration coach with AI tools starting in Vercel’s V0!
It’s not just a water logger:
• 
Adjusts your hydration goal in real time by your weight, your intake (beyond water) and activity level
• 
Factors in sodium from meals (just take a pic and calls Gemini API) Go over 2300 mg a day and your water goal goes up
• 
Personalized Coaching and tips based on your wellness goal (energy, focus, digestion, etc.)
• 
Drinks that hydrate are green, 
dehydrating ones are red
Someone actually asked:
“So if I drink 6 beers, I hit my water goal?” 
Not quite—each beer dehydrates you by 6oz. That comment led to a key UX update.
Try the mobile PWA: Sip Pal - Stay Hydrated, Stay Healthy
Pro tips: Add it to your home screen on your phone and tap it like an app. Add your custom water bottle! Have fun and stick with it. Ive experienced sharper focus, better work outs and overall energy without coffee binges!
Eventually will get this to Test flight so i can add nudges/ notifications — DM me if you want early access to the beta
On using V0: great for rapid ideation, probably best UI iterations than the other tools out there. Struggled with anything related to gemini integration and db things. Lots of bugs and I spent valuable credits going in circles with the V0 agent.

Would love your take:
• Does this “hydration coach” idea resonate?
• What would make it genuinely useful ?
• Anything good, bad, ugly ?
Feel free to leave and comments on this post. happy to jam!
Also Im doing evals, testing which LLMs build better features across Claude, GPT-4, and SWE-1.
Happy to share insights if that’s of interest too!
