Nutrition tracking that fits into real life.
We built Flun because we wanted a calorie tracker that didn’t feel like a second job.
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.
Your targets reflect what you’re trying to do. Lose fat. Build muscle. Maintain. We also support GLP-1 users who want to protect muscle and stay on track. The dashboard shows where you stand, and the coach helps you make small changes that move you forward.
Miss a day? Keep going. Heavy weekend? Adjust and move forward.
We use Flun every day.
It’s $6 a month, with a 7-day trial so you can see if it fits. We'll remind you before your trial expires.

Answers before you start
Everything you need to know about logging, privacy, and getting results.
Will this still work if my schedule is unpredictable?+
Yes. Flun is designed for real life. Irregular meals, busy weeks, travel, or missed logs are all expected — your targets adapt to what actually happens, not what was planned.
Do I have to count calories?+
Not unless you want full control. Flun works seamlessly with photos, voice, or text. You can edit calories if you want precision, but your plan focuses on patterns over time — not perfect numbers every day.
How does Flun adjust my targets?+
Flun adjusts your daily targets based on what you eat and what you do. Your long-term goals stay under your control, with small nudges from the AI coach to help you stay on track.
What if I miss a day?+
Nothing breaks. You can catch up with a retroactive summary if you want, or just keep going. Flun focuses on your weekly rhythm, not streaks or perfect days.
Can I track workouts too?+
Yes — and it works the same way as food. Log activity by voice, text, or photo, and Flun uses it to balance your daily targets automatically. No separate systems, no extra effort.
Does it work for meal prep and repeats?+
Absolutely. Save favorites, reuse meals with one tap, and let Flun remember portions that work for you — so repeat meals get easier, not boring.
Is my data private?+
Yes. Your data is private and never sold. You can delete your history at any time — and you’re always in control of what you log and keep.
