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.
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.
Thank you! Good news: that nudge already exists. You can set gentle reminders every 2 or 3 hours (you can set this in settings), they stay quiet at night and stop once you hit your goal for the day.
On the thirsty fish idea, I actually made the opposite call early on. The fish never looks sad or needy because I did not want a guilt pet, the reminder taps your shoulder and the tank stays a place you want to come back to.
Really appreciate you thinking this deeply about it on day one. :)
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.
Thank you, I might have to steal "alive instead of just another chart" as a promotion header somewhere :D
honestly the little fish swimming up as i log water is such a cute touch, makes me actually want to keep going. loving that it works fully offline too
Thank you! Really glad you're enjoying it.
