Frequently Asked Questions
Everything you want to know about the Suu water tracking app — features, the science, integrations and pricing.
What is Suu? Suu is an AI-powered health app for iOS and Android that unifies three things most apps keep separate: water tracking across 91 beverages, photo- and voice-based calorie and macro tracking, and live GPS exercise tracking with your route drawn on a map. The three are connected — a recorded run raises your water goal, and a logged meal adds the water your body needs to digest it. It includes the Suu Index (a 0–100 hydration score), the Adaptive Hydration Brain, friend leagues, Apple Health & Health Connect sync, widgets, Dynamic Island and Siri — in 7 languages (English, Turkish, Arabic, German, Italian, Russian and Hindi).
Getting started
What is the Suu app?
Suu is an AI-powered health app for iOS and Android that combines three things most apps keep separate: hydration across 91 beverages, calorie and macro tracking from a meal photo or your voice, and live GPS workout recording with your route on a map. The three are connected — a recorded run raises your water goal, and a logged meal adds the water your body needs to digest it. It works in 7 languages: English, Turkish, Arabic, German, Italian, Russian and Hindi.
Is the Suu app free?
Yes. Core water tracking, exercise tracking and 3 AI meal analyses per day are free forever on both iOS and Android. Premium adds unlimited AI analysis, photo meal recognition, advanced macro statistics, PDF and CSV reports and ad-free use, with a 3-day free trial and monthly or yearly plans.
Which devices does Suu work on?
Suu runs on iPhone (iOS) and Android phones. Workouts from an Apple Watch, a Wear OS watch, Fitbit, Garmin, Samsung or Mi Band reach Suu through Apple Health and Health Connect. Suu also has its own Apple Watch app for adding water, logging meals by voice and recording GPS workouts.
How do I download Suu?
Download Suu free from the App Store (iPhone) or Google Play (Android). You can also start instantly in Guest Mode without signing up.
Does Suu count calories from a photo?
Yes. Photograph your plate and Suu AI returns calories, protein, carbohydrate and fat in seconds — no database search, no weighing. The photo is not stored permanently. Three AI analyses per day are free forever; unlimited analysis and photo recognition are part of Premium.
Can I log a meal by speaking?
Yes. Say something like “a bowl of lentil soup and a glass of ayran” and Suu separates the solids from the liquids automatically: the soup becomes calories and macros, and the ayran also counts toward your hydration. Speech is turned into text by your device's own operating system (Apple Speech on iOS, SpeechRecognizer on Android) — the audio never reaches Suu's servers.
Does Suu have a barcode scanner?
No. Suu logs food by photo, by voice and by text, but it does not scan barcodes, and its food database is smaller than MyFitnessPal's. If barcode-first logging of packaged products is your main need, MyFitnessPal is the better choice.
Does Suu track runs and rides with GPS?
Yes. You start, pause and finish a workout inside Suu and watch distance, duration and pace update live; when you finish, your route is drawn on the map. Running and walking report distance, pace, average speed and calories burned; cycling adds speed and elevation. Around 50 sport activities are supported.
Is Suu an alternative to Strava?
For recording a run or ride and tying it to what you ate and drank, yes. Suu does live GPS tracking with a route map and reads workouts from Apple Health and Health Connect. It does not have segments, leaderboards, kudos, a social feed, power-meter analysis or a route planner — if those matter to you, Strava is the right answer, and you can use both: a workout recorded in Strava reaches Suu through Apple Health or Health Connect.
Does an exercise session change my water goal?
Yes, automatically. Every workout — whether recorded live in Suu or read from Apple Health / Health Connect — raises your daily water target, and Suu suggests 300–500 ml of calorie-based extra water after training. Meals do the same in the other direction: their protein and sodium content adds a digestion-water requirement.
Can Suu replace a separate calorie counter, workout tracker and water app?
That is what it is built for, and the three pillars feed each other rather than sitting side by side. Two honest limits: the food database is smaller than MyFitnessPal's with no barcode scanning, and there is no social feed or segment system as in Strava. If you deliberately track micronutrients, Cronometer remains stronger.
What are macros and does Suu calculate them for me?
Macros are protein, carbohydrate and fat — the three nutrients that supply calories. Suu sets automatic macro targets from your profile and goal, tracks them per meal and per day, and gives each meal a 1–100 nutrition score for how balanced it was. Values are written back to Apple Health and Health Connect.
What languages does Suu support?
Suu is available in 7 languages: English, Turkish, Arabic (with full right-to-left support), German, Italian, Russian and Hindi, including native drink names and accessibility for VoiceOver and TalkBack.
Your goal & the science
How is my daily water goal calculated?
Suu starts from about weight (kg) × 35 ml, then applies activity, age, sex and BMI factors, subtracts roughly 25% you get from food, adds for pregnancy or breastfeeding, and clamps the result between 1,500 and 4,000 ml. The goal recalculates whenever your profile changes. This is general guidance, not medical advice.
How much water should I drink per day?
For most adults a common range is about 2–2.5 liters, but weight (kg) × 30–35 ml is more accurate. Suu personalizes this from your weight, activity, age, sex and BMI. General guidance, not medical advice.
What is the Adaptive Hydration Brain?
It is Suu's behavioral AI layer. While you use the app, it builds a profile of your tempo, pace, drink variety, consistency and activity, then adapts 24 decision areas such as notification rhythm and coaching depth. Personalization starts on day 3; new users always get a safe default.
What is the Suu Index?
The Suu Index is a 0–100 daily hydration score built from completion (50%), regularity (20%), timing (20%) and over-intake (10%), with labels from Excellent to Weak. It measures hydration quality, not just quantity.
Drinks & the hydration model
How many drinks can I track in Suu?
Suu includes 91 drinks across 12 categories, plus Starbucks, Greenwich and Nevada brand menus. Each drink has a real hydration factor, so coffee, tea, juice and more are counted with their true contribution.
Does coffee or tea count toward my hydration?
Yes. Suu uses a compound hydration model: water counts 1.0, herbal tea 0.9, coffee 0.8, energy drinks 0.5 and alcohol −0.5. Caffeine itself is not penalized; only sugar and alcohol add an extra-water need.
How do the smart notifications work?
Suu learns your drinking pace over 14 days and sends contextual reminders such as "You're at 32% — 2,400 ml to go" instead of generic alerts. When you reach your goal, the remaining reminders for the day are cancelled.
Integrations & devices
Can I sync water with Apple Health?
Yes. On iOS, Suu syncs two-way with Apple HealthKit for water, steps, active energy and workouts. On Android it uses Health Connect / Google Fit. Sync runs automatically about every 15 minutes.
Is there an iPhone widget and Dynamic Island support?
Yes. Suu offers Home Screen and Lock Screen widgets in 3 sizes, plus a pace-aware Dynamic Island and Live Activities that show whether you're ahead, on time or behind your personal rhythm — not just a raw counter.
Can I track water with Siri or voice commands?
Yes. You can add water with Siri Shortcuts and with in-app custom voice triggers (for example "coffee" → 200 ml), in all 7 languages.
Social, leagues & comparisons
What is the league system and how does it work?
Leagues let you run a weekly water-drinking competition with up to 4 friends. There's a leaderboard, goal-completion percentage and streak rivalry, and iOS and Android users can compete in the same league.
Is Suu better than WaterMinder or Hydro Coach?
Suu adds things those apps don't have: an Adaptive Hydration Brain, the Suu Index, social leagues, 91 drinks, a pace-aware Dynamic Island, a virtual pet, PDF/CSV export and 7 languages including Arabic. WaterMinder and Hydro Coach are strong on basics; Suu focuses on personalization and motivation. See the full feature comparison.
Privacy, data & premium
Will I lose my data?
No. Suu syncs to the cloud and works offline with background sync, so your history is preserved across devices. You can sign in with Apple, Google or email, and securely delete your account at any time.
How much does Suu Premium cost and is there a free trial?
Suu Premium offers a 3-day free trial, then monthly or yearly plans (billed through the App Store or Google Play). Premium unlocks unlimited AI meal analysis, photo meal recognition, advanced macro and nutrition statistics, PDF/CSV reports and 7/30/365-day charts, and removes ads.
Who developed Suu?
Suu was developed by Furkan Mert Fındıklı, an indie developer from Istanbul, Turkey, specializing in Flutter and HealthKit. Content and localization are supported by the wider Suu team.
