Every hydration app I tried either cost money, showed ads everywhere, or required creating an account just to track water. So I built Hydrate Yourself. It calculates your personal daily water goal based on weight, activity level, gender and climate. Then reminds you throughout the day based on your wake and sleep time. Completely free. No premium tier, no subscriptions, no account, no ads, ever. Your data never leaves your device. Built in Flutter. Fully offline.










Hey Product Hunt! Maker here.
I built Hydrate Yourself which reminds user to drink water on regular basis. There are a dozen of such apps published on Play Store but all of them either require an account creation and subscription or have ads beyond imagination just to log a glass of water.
Therefore I decided to build one myself

The problem I was solving was personal first. I wanted an app that calculated a real daily goal based on my weight, activity level, gender, climate and I wanted it to remind me reliably throughout the day without needing to keep the app open.
The approach was to strip everything down to what actually matters. No account because your water intake data should live on your device, not a server. No ads because the interruption breaks the habit you are trying to build. No subscription because hydration tracking is not a premium feature. Everything is calculated locally, reminders fire directly from the device, and the app works entirely offline. If you ever want a fresh start, you can delete all locally stored data instantly from the Settings screen.
Would love feedback from anyone who tries it.
Love that you factored climate into the daily goal calculation. Most apps just throw a flat 2L recommendation at you, so seeing weight plus activity plus environment working together shows real thought went into the logic.
Love that you factored in climate alongside the usual weight and activity inputs. Most apps skip that, and it makes a real difference for the goal calculation.
