Hydratica.

Tap the glass on your Lock Screen. Watch the it fill. Back to your day. Hydratica is a water tracker you never have to open. No launch, no loading, no typing numbers. One tap from the Lock Screen and it is logged. Most hydration apps fail because logging water takes more effort than drinking it. Hydratica removes every step but one. WHAT YOU GET - Lock Screen Glass widget — log without opening the app - Full-screen fill animation for when you do open it - Custom daily goal - Intake calendar with streak count - Unlimited reminders - Six color themes and matching app icons (only one is blue) - Fully offline — your data never leaves your device (each device keeps its own log) - No account, no ads, no sign-up HOW IT WORKS Hydratica is free to download and includes a free trial of everything above. When the trial ends, a single one-time purchase unlocks the app permanently. No subscription, ever. Buy once and it is yours forever. One tap. One glance. Done.
