Free Macro Tracker — Protein, Carbs & Fat from a Photo

A Macro Tracker That's Actually Free

Most macro tracking apps put the feature you want — gram-level protein, carb, and fat targets — behind a subscription. MyFitnessPal charges around $20/month for macro tracking by gram; Lose It! gates it behind Premium. Bento Bunny tracks your macros automatically and is free during its iOS beta. No paywall on the one feature you came for.

Macros Without the Maths

Traditional macro tracking means knowing the breakdown of every food, weighing portions, and adding it all up. Most people quit within a week. Bento Bunny calculates macros from a photo: snap your meal and get total calories plus grams of protein, carbs, and fat — no food scale, no label reading, no spreadsheet. You can also scan a barcode or type what you ate.

Why Macros Matter

Calories tell you how much you eat; macros tell you what you eat — and that drives how you feel and progress.

• Protein preserves muscle, keeps you full, and has the highest thermic effect. Active people typically aim for 1.6–2.2g per kg of body weight.
• Carbs fuel high-intensity exercise and brain function; the right amount depends on your activity and goals.
• Fat supports hormones and nutrient absorption and is calorie-dense at 9 cal/g, so it's worth tracking for overall intake.

Two meals with identical calories can have very different macro profiles — tracking macros is how you tell them apart.

Set Targets, Then Hit Them Automatically

Bento Bunny sets sensible macro targets based on your calorie goal, body weight, and activity, and you can override them to match a specific diet — high-protein, keto-leaning, or a ratio your nutritionist recommended. As you log meals, your protein, carb, and fat totals accumulate automatically so you can see at a glance whether you're on target for the day. Not sure what your targets should be? Use the free macro & calorie calculator.

Free, Fast, and Private

Bento Bunny is free during its iOS beta, logs a full meal in about five seconds, and — on iOS 26+ — processes meal photos on-device so your photos never leave your phone. It's the rare macro tracker that's free, fast, and private at the same time.

Start Tracking Macros Free

If a paywall has put you off macro tracking, Bento Bunny removes it. Every photo gives you a full macro breakdown — free during the beta. Join the iOS beta and start tracking.
