About

Strict Water Reminder

Features
Read full description

Most apps send a notification. You tap dismiss. Nothing changes. Hydrate is a simple drink water reminder built differently. Strict Mode requires real proof before you can move on, helping turn hydration from a good intention into a daily habit. You know you need to drink more water. The problem is usually not knowledge—it is consistency. Hydrate helps you stay on track with clear reminders, daily water intake tracking, and a focused routine that makes each drink count. WHAT HYDRATE HELPS YOU DO • Set a daily water goal • Receive clear drink water reminders • Track your water intake throughout the day • Build a consistent hydration habit • Use Strict Mode when ordinary reminders are too easy to dismiss • See your progress without unnecessary clutter Hydrate is designed for people who want a practical water tracker and drink water reminder that keeps them accountable without turning hydration into a complicated wellness project. Start small. Drink water. Stay consistent. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
