“I rarely leave reviews, but there needs to be more appreciation for this app — 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 like a lot of the other trackers. Lifetime option is always a big plus. Thanks for the app :)”

“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), and I actually enjoy tracking my drinks now. The streaks keep me motivated. This app actually helped me drink more water - and I can really feel the difference! My head doesn't hurt as often, and I just feel more energetic overall. Walter the watermelon is so cute, I love him! Totally recommend!”

“So far the app looks and works great but 1 feature I miss is menu bar icon so the app runs in the background and doesn't show on my apps list when I switch between them.”
