Koiven turns drinking water into something you actually want to open. Log a drink and your on-screen aquarium fills: the water rises and your fish, Zenna, swims. Under the calm surface it's a complete tracker: personalized daily goal, streaks, weekly dots, and free custom drinks. Private by design: fully offline, no account, no email. Your data stays on your device. Free to use; Pro unlocks more fish, themes, and drink slots. Android today, iOS once the app funds it.
honestly the little fish swimming as my water count went up was such a weirdly satisfying little dopamine hit, way better than staring at a plain progress bar. offline only is a huge plus too.
Exactly what I was going for. A progress bar never made me want to open the app again. Even after four months of staring at this tank while building it, I still log my own water in it every day.
Thanks for trying it on launch day.
Ps- the fish are interactive, tap one and watch it react.
Love the aquarium idea, that's genuinely clever motivation. One thing I'd love: a gentle nudge when I forget to log for a few hours, maybe Zenna swims to the top looking thirsty or something subtle. That tiny reminder could really help build the habit without it feeling pushy.
love how the aquarium actually responds to your hydration, like watching Zenna swim up as the water rises is such a clever way to make a tracker feel alive instead of just another chart.
