Meet Boon!

I went from 225 to 175 lbs, and I investigate fitness products with no sponsors and no affiliate links. I built this app around the exact system that worked for me.

Questions

Is it really free?

Yes. Your first 2 weeks are free with no card: your calories, your meal plan and your first 2 weeks of training. After that, weeks 3 to 12 are part of The Full Stack. If you don't want it, you don't pay anything.

Do I have to count calories?

No. Every portion is already sized for you. Pick one of the 3 options for each meal and you're on plan.

I don't have a gym. Does it still work?

Yes. Pick home with dumbbells or no equipment in the quiz and your workouts are built for that. You can change it any time.

Do I need to buy supplements?

No. Most people end up buying less. The app tells you the short list that's worth it, and Stack Check tells you what to skip.
