Water Lu: Track water, grow Lulu, earn pixel collectibles

Hi, I’m Dens, the maker of Water Lu.

I built Water Lu because logging water felt like a chore. I wanted it to be fun, so every goal you hit adds a new find to your pixel-art collection.

Water Lu is a pixel-art water tracker for iPhone and Apple Watch. You log each sip, Lulu grows with you, and every day you hit your goal a drift bottle washes ashore. Open it for a pixel collectible. The more evenly you drink, the better your odds of Rare, Epic, and Legendary — and the odds are public in the app, not hidden behind a paywall.

A few things I cared about while building it:

• One purchase. No subscriptions, no ads, no in-app purchases. Collectibles can only be earned by drinking; they can’t be bought.
• No account, and no third-party analytics or ad SDKs. Records stay on your devices, with optional iCloud sync and optional write-only Apple Health.
• Even drinking is rewarded over chugging: going past 1.5× your goal earns nothing extra, and drinking too much in an hour gets a gentle warning.
• Log from the app, widgets, Control Center, Dynamic Island, Siri, or Apple Watch.

There are 194 collectibles across five seas (Ocean, Garden, Polar, Coral, Galaxy), plus the Drink Café and seasonal or holiday sets.

Water Lu requires iOS 18 and watchOS 11. It’s on the App Store now, and it’s 50% off for Black Friday until Nov 28.

I’d love your feedback, especially:
1) Does the drift-bottle loop make you want to come back the next day, or does it feel like extra work?
2) Is anything about logging (amounts, drink ratios, reminders) getting in your way?

Happy to answer questions. Thank you for taking a look.
