Features

Tiny things that add up to a habit.

Every feature in Hydro Panda exists for one reason: making it easy and joyful to drink water more often. No leaderboards. No social pressure. Just you and your panda.

Smart reminders

Gentle nudges through the day with custom hours and quiet times. Never the kind of buzz that makes you glare at your phone.

Panda fills with you

Every sip you log slowly fills a panda-shaped vessel. Real water physics. Slosh it. Watch it settle. The signature delight feature.

6 vessel skins, free

Mason jar, bottle, glass, cactus, panda, classic circle. Pick your daily vibe — every one is unlocked from day one.

Streaks & milestones

7, 30, 100-day streaks with celebration moments. Miss a day? Your panda still loves you. Streaks pause, they don't shame.

Coffee, tea & more

Track water, coffee, tea, juice, and milk — UI tints to match each drink. Realistic hydration values, not a guilt-tripping multiplier.

Weekly reports

Beautiful charts of your hydration history, by day and week. See the patterns. Spot the dips. Pat yourself on the back.

Achievements

Unlockable milestones as you hydrate — first sip, perfect week, hydration legend. Cute badges, no pressure.

Privacy first

No accounts. No cloud. No tracking. Your hydration history stays on your phone — exactly where it belongs.

Your sip sidekick

Meet the panda who fills with water.

Most water apps show a number. Hydro Panda shows a panda — one that slowly fills as you drink, sloshes when you tilt your phone, and looks just a little bit smug when you hit your goal.

A panda is a better progress bar.

The panda's body is your daily goal. Each drink raises the water level. Tilt your phone and the surface tips with you — actual fluid simulation, not a fake animation. Hit 100% and the panda gets a tiny celebratory blink.

Tap to log a drink in less than a second — your panda starts filling immediately.
Six vessel skins — switch from panda to mason jar to cactus when you want a different mood.
Drink-tinted UI — coffee shifts the panda toward warm browns; juice toward sunset orange. Tiny touches.
Built in Flutter — buttery-smooth 120 Hz on iOS, Material You on Android.

Why hydration matters

Your body is mostly water on the move.

A few facts to keep in your back pocket. Hydration isn't a wellness trend — it's the most basic upgrade you can give your day.

60%

of your body weight is water. Lose just 1–2% and you'll feel it.

73%

of your brain is water. Hydration is, literally, head-clearing.

14%

drop in focus from mild dehydration — before you even feel thirsty.

8

glasses isn't a myth — it's a baseline. You probably need a bit more.

How it works

Three taps to a healthier habit.

No onboarding video. No forty-question survey. You're tracking water, not training a model.

1

Set your goal

Pick a daily target — Hydro Panda suggests one based on your weight, but you can override it any time. Set quiet hours for reminders.

2

Tap to log

One tap on the panda logs a glass. Long-press to log a custom amount or a different drink. Your panda fills in real time.

3

Watch your streak grow

Hit your goal and the day turns into a streak day. 7-day, 30-day, 100-day milestones unlock badges. Miss one? Streak pauses — no shame.

Pricing

Free forever. Pro is three bucks, once.

No subscription. No tricks. No paywall on the core experience. The honest pricing of an app made by one person who isn't trying to upsell you.

Free, forever.

All eight drink types, all six vessel skins, every milestone, every chart, every reminder. Free is the full app. A small banner ad sits at the bottom — that's how this stays a real, sustainable indie project.

If you'd like to remove the ad and toss me a tip for years of updates, Hydro Panda Pro is a one-time $2.99. That's it. No annual renewal. No "lite" version. Family Sharing supported on iOS, restorable on both stores.

Optional

One-time. No subscription. Restorable.

Removes the banner ad — forever.
Supports a solo indie dev who replies to every email.
Family Sharing on iOS, account-bound on Google Play.
All future updates included. No new tier coming.

Privacy

No accounts. No cloud. No tracking.

Your hydration history is yours. It lives on your phone. We don't run servers, we don't run analytics, and we never see a single sip you log.

Stays on your phone

All hydration data is saved in your device's local storage. Delete the app and it's gone — there is no remote copy.

No third-party analytics

No Firebase, no Mixpanel, no Amplitude. The only network calls are AdMob (free tier) and the App/Play Store for purchases.

You're in control

Manage ad preferences in Settings any time. Decline App Tracking Transparency on iOS — ads still work, just non-personalized.

Built by one person who actually drinks the water.

Hi, I'm Naveen — solo indie dev behind Playpal Apps. Hydro Panda started as a Flutter side project to fix a habit I kept losing. The panda came in version two, the fluid simulation in version four, and the obsession with making it cute hasn't stopped since.

I make a small handful of apps that I'd actually use myself. No VC funding, no growth team, no dark patterns — just careful little tools that respect your time and your data. If you have feedback, my email is in the support page and I read every one.
