Hands-free logging: tell Amy what you ate and she transcribes it into dishes.

Frequently asked questions
How does Calister work?
You answer a few questions when you sign up — age, weight, goal, and pace — and get a daily calorie and macro target. From there you log meals by photo, voice, text, or barcode, and the app updates what’s left for today.
Is the app free?
Daily logging, the food database, water and weight tracking are free. A Premium subscription unlocks the AI coach, unlimited photo logging, voice logging, meal analysis, and advanced insights.
Where does the nutrition data come from?
From the Ministry of Health database, packaged-product catalogues, and brand data. Every value shows its source and confidence level, so it’s always clear where a number came from.
How is my calorie target calculated?
From your resting metabolic rate plus your activity level and the goal you picked. If your actual pace differs from the forecast, Calister offers to recalibrate the target.
Can I correct what the app detected?
Of course. Every dish opens up for editing the amount, swapping the product from the database, or adding an ingredient — the numbers update right away.
What happens to my data?
Your data is stored in your account, never sold to third parties, and you can delete your account along with everything in it from the settings.
