About
Hydra helps you drink the right amount of water every day and keep track of your meals and fasting, in an app built for the heat and the way we live.
A water goal that fits your climate
Hydra sets your daily water goal from your weight and raises it automatically on hot days. Log water with one tap and follow your progress through the day.
AI meal scanner
Snap a photo of a meal or drink and get an estimate of its calories, protein, carbs, fat and water content in seconds. Add a short description of the meal for a more accurate result.
Islamic fasting
Turn on Islamic fasting to track your fast from Fajr to Maghrib, with a countdown to Iftar and prayer times that update automatically for your location. Water and meal logging pause during fasting hours only and come back after Maghrib.
Intermittent fasting
Pick your plan (such as 16:8), start and stop your fast easily, and follow your streak and completion rate.
Challenges with friends and family
Create a challenge or join one with an invite code, and compete on water, calories or protein with a live leaderboard.
See your progress
Daily, weekly and monthly history for water, meals and fasting, with your averages and the days you hit your goal.
Smart reminders
Water reminders through the day, a reminder before each prayer, and a pre-Fajr reminder when fasting is on.
Arabic and English
A full interface in both languages, with right-to-left support for Arabic.
Start for free
The free plan includes water tracking, Islamic and intermittent fasting, 2 meal scans a day during your first 5 days, and one 1-week challenge.
