Hydratica.

The one-tap water tracker.

$3.99 · Designed for iPad. Not verified for macOS.

The simplest water tracker on the App Store. One tap on your lock screen. No subscription. No account. Just water. One tap. No friction. Are you drinking enough water? This summer is forecast to be the hottest on record. Heatstroke, heat exhaustion, and heat-related cognitive decline are no longer edge cases — they are mainstream health risks affecting everyone, everywhere, every record summer that passes. Hydration is no longer a fitness metric. It is survival infrastructure. The difference between feeling sharp and feeling wrecked in extreme heat is often as simple as whether you drank enough water before noon. The reason most people don't track it isn't discipline — it's friction. Opening an app, waiting for it to load, logging an exact volume — that sequence kills the habit before it starts. Hydratica removes every step except one. You down a glass of water. You tap + directly on your lock screen. Your phone stays locked. No passcode, no navigation, no clunky interface. One tap. One immediate visual. Back to your day. THE LOCK SCREEN TIDE Every tap raises a minimalist wave bar on your lock screen. When you hit your daily goal, it's fully submerged. Glance, feel it, move on. No numbers to interpret. No app to open. Your screen is your reminder. THE IMMERSIVE VIEW Open the app when you want to go deeper. A full-screen water animation fills your screen with every glass — calm, satisfying and simple. No pings. No guilt trips. No fitness dashboard. Just water. One tap at a time.
