“I’ve tried a few hydration apps before, but this one is by far the most fun and motivating! The reminders are gentle (not annoying)… Walter the watermelon is so cute, I love him!”
“Really cool app for tracking daily water intake. Love the social aspect. It actually keeps me motivated to drink more water!”
“A genius app that allows you to easily control the amount of fluids consumed during the day. I recommend it to anyone who has trouble drinking water due to a busy schedule!”
“It has a clean, cute interface but also tons of functional features like detailed stats and the option to add friends, but it’s all simple enough to not be a headache to navigate.”
“Helped me a lot to get my daily water dosage in. Walter helps me to be right on track!”
