What is HydroPal

The smart water bottle cap replaces the existing cap on your water bottle. The product is compatible with most major brands, including Swell, Nalgene, Hydro Flask, Contigo, and others.

Inform Hydration Level

Our cap has a built-in sensor that tracks when water enters and leaves the bottle, and registers the amount in your app to show you how much you’ve hydrated that day.

Gamified Experience

The fish tank game helps kids track their hydration progress. The smart water bottle will transmit the data to the app.  Kids earn coins when they drink water, and can use those coins to buy more fish and decorations for their fish tank.

Our Product Aspirations

I was concerned about my kid's hydration before getting HydroPal. Now, I know he's well hydrated and practicing healthy habits.

 I used to forget to drink water. With HydroPal, I now receive a reminder from my phone! That's so cool! 

I used to try and keep track of how many water bottles I drank per day, but I often just lost count. Now, HydroPal records my hydration level. Plus I can interact with my friends too!

It's great seeing my kid learning to form healthy habits with the help of HydroPal!
