About this app
Flun is the AI calorie counter and macro tracker for people who hate logging food. Snap a photo, say what you ate, or type — Flun's AI logs your meal in seconds. Track calories, protein, carbs, and fat with adaptive daily targets. Free trial.
Log meals and workouts by typing, speaking, or taking a photo. Go deep and scan every label if you want precision. Or keep it simple and just describe your meal. It works either way.
Log the way that fits your day:
• Use favorites, or log by text, photo, or voice. Mix and match.
• No barcode marathons — just describe what you ate
• Save frequent meals for instant one-tap re-logging
Targets that adapt to you:
• Daily calorie and macro targets adjust based on what you eat and what you do
• Four goal modes: Lose weight, Maintain, Build muscle, or GLP-1 support
• Not fixed numbers — Flun learns your patterns
Macro guidance that actually helps:
• Macro targets that adjust with your food
• Clear, actionable breakdown of protein, fat, and carbs
• GLP-1 support mode: Flun works alongside GLP-1 medications like Ozempic®, Wegovy®, Mounjaro®, and Zepbound® with protein-first macro guidance built for users on these treatments.
Built-in AI coaching:
• Personalized insights based on your 7-day eating patterns
• Coaching that adapts as you log
• Focuses on trends and consistency, not perfection
Track your progress:
• 28-day calorie and macro trend charts
• Weight tracking with goal timeline projections
• The dashboard shows where you stand
Miss a day? Keep going. Heavy weekend? Adjust and move forward.
Share and earn:
• Refer friends and earn free subscription months
• The more friends you refer, the more you earn

Hi Amy, thanks for the honest feedback!
Flun's AI-powered nutrition analysis has real ongoing costs, which is why it's subscription-based. That said, every new user gets a 7-day free trial to see the full value before paying, and we offer monthly and annual plans to fit different budgets. We'd love to have you back!
