Question 1

What is Nibble?

Nibble is an AI-powered nutrition tracking app for iOS. Take a photo of any meal and get a complete nutritional breakdown in seconds — calories, protein, carbs, fat, and 20+ micronutrients. It supports 10 diet protocols, has a built-in AI diet coach, and includes progress analytics, achievements, and 16 home screen widgets.

Question 2

How does the AI photo scanning work?

Accepted Answer

Point your camera at any meal and tap capture. Our AI identifies individual food items, estimates portions, and calculates the full nutritional profile. It works with home-cooked meals, restaurant dishes, packaged foods, and multi-item plates. The analysis typically takes 2-3 seconds.

Question 3

What diet protocols are supported?

Accepted Answer

Nibble supports 10 diet protocols: CICO (Calories In, Calories Out), Keto, Intermittent Fasting, Low-Carb, Mediterranean, Carnivore, Paleo, Vegan, High Protein, and DASH. Each protocol comes with AI-calculated daily targets based on your body, goals, and activity level, plus a monthly compliance calendar.

Question 4

Is my data private and secure?

Accepted Answer

Yes. Your meal photos are analyzed by AI and never stored on our servers after processing. Your nutrition data is stored securely using Supabase with row-level security. We don't sell your data to third parties. See our Privacy Policy for full details.

Question 5

What can I do on the free plan?

Accepted Answer

Upgrade to Premium for unlimited AI scans, 10 diet protocols, AI coach, progress analytics, extended nutrients, widgets, and achievements.

Question 6

Does Nibble work with Apple Health?

Accepted Answer

Yes. Nibble automatically syncs your nutrition data with Apple Health, including calories, protein, carbs, fat, fiber, sugar, and sodium. This happens seamlessly in the background whenever you log a meal.

Question 7

How accurate is the AI analysis?

AI photo analysis provides estimates that are comparable to manual entry for most common meals. For packaged foods, use the barcode scanner or nutrition label camera for exact data. You can also correct any item in an AI analysis to fine-tune the results. The AI improves as you use it.
