About
Snap a photo of your plate: calories and macros count themselves. Upload your blood tests and the app tells you what to eat.
Zru & Hudnu is for people tired of manual tracking and food bans. Eat normal food, hit your targets and watch your weight and wellbeing change.
WHAT YOU GET
• A diary in seconds: photo, barcode scan or search, and the food is logged
• Personal food lists: your blood tests show what to eat more often and what to pause
• Marker dynamics: retest later and see on a chart how your nutrition moves the numbers
• An AI assistant: ask what to eat and get a snack that lands right on your remaining targets
• Recipes with exact macros: your own and ready made ones, with a shopping list
• Your week on one screen: calories, weight and macros, so you see what works
• Water reminders: gentle nudges through the day and a counter of what you drank
• Steps and walks: we count your steps, record your walk route by GPS and give rewards on the map for moving
HOW IT WORKS
1. A short setup: your goal, your numbers, and your calorie target is ready
2. Log food with a photo, a scan or a search
3. Upload blood tests when you have them: recommendations become personal
WHAT YOU CAN SKIP
• No bans: your favourite food fits your goal
• No manual entry: food databases and AI do the boring work
• No guilt: the app encourages consistency instead of shaming slips
Your lab data is visible only to you: it powers your recommendations and is never shared with third parties.

What's New in Zru & Hudnu
1.0.30
September 22, 2026
A dial for the whole day: tap calories, protein, fat or carbs on the home screen and adjust every food of the day at once. The Auto button fits portions to your targets by itself, and if the logged foods cannot reach them it says what to add or remove. The rewards map without location access now explains how to enable it instead of bouncing to settings. Plus stability fixes.
