The best macro tracker. And the only one you'll enjoy.
Targets that adapt to your body every week. Log food with a quick photo, cook from macro-tuned recipes, and hatch a dino buddy that grows every day you hit your goals.
The clever science of the big trackers, plus a game none of them have.
Three things no other tracker does this well.
Log a whole meal in one photo.
Snap your plate, say it, or type it. The AI reads the food and fills in your macros in a moment. So quick you'll actually keep it up.
Turn any food video into a recipe.
See a recipe you like on TikTok, Instagram or YouTube? Share the video straight to Macrosaurus, or paste the link. We pull out the full recipe so you're not scrubbing a 30-second video, cost every macro to the gram, and slot it into your library sorted by what fits your day. Cook it, log it in a tap, feed your streak.
The reason you'll never miss a day.
Hatch one egg and raise one dino. It coaches you in its own voice, bonds and evolves every day you hit your targets, and fights for you in Daily Hunts and Boss Climbs. Nothing else makes hitting your numbers this good.
Real science. No black box.
Adaptive targets
Your calories and macros retune weekly from your real trend weight, the way a good coach would.
Fully transparent
See exactly why your targets changed each week. No mystery numbers, no guessing.
Research-backed
High-protein targets and trend-weight smoothing grounded in the actual literature.
Body-fat tracking
Photo-based composition reads, so you follow real change, not just the daily scale.
The best tracker you can put on your phone.

I tried every macro tracker going, and quit all of them. Accurate, maybe — but a chore to open. So I built the one I actually wanted: the adaptive science the big trackers use, logging that takes seconds, and a game that makes hitting your numbers genuinely feel good. It's early days and I'm building it in the open — free to start, no card, no hype. If you give it a go, tell me what you think.
