Hit your numbers without guessing.
ZMacros learns what you really burn from your own logs and weigh-ins, then keeps your calorie target honest. Logging takes seconds: scan a barcode, snap a photo, or copy yesterday's breakfast in one tap.

Adapts to you
A target built from your own data.
Formulas guess your burn. ZMacros estimates it from what you log and how your weight moves, and only changes your target when the evidence is good enough.
Example data, not a real user's results.
Reads your logs and weigh-ins
What you ate, compared with what your weight actually did. Half-logged days count for less.
Works out what you burn
Your own number, not a formula's average, shown as a range with a plain confidence level.
Moves your target carefully
Small, measured changes as the evidence builds, and none while it's still guessing.
Nutrition
Macros, fibre and micros.
Protein, carbs, fat and fibre on the Today screen, with vitamins and minerals one tap away, so you can see what your food is actually short on.

Make it yours
Your app, your way.
ZMacros is built to look and work the way you like. Change how it looks, and choose which parts of your screens you see and in what order. These are real app settings. Try changing the look and moving things around on the phone; nothing here is saved.
Change the look
- Light, Dark, or follow your phone.
- Any accent colour, from presets or a colour wheel, or let the app pull colours from your photo.
- A plain background, a custom background colour, or your own photo from your camera roll as the background.
- Info cards that are plain or frosted glass, with a slider for how clear the glass is.
- Compact, Default or Large text.
Arrange your screens
- Tap Edit on Today or Progress to drag sections into the order you want, or move them with the arrows.
- Hide the parts you do not need, such as Macros, Steps, By meal, Weight or Vitamins & minerals, and bring them back any time.
- Tap Done to save your layout. Try the Layout buttons above to see it.

Do I need to pay to get adaptive targets?
No. Adaptive targets, barcode scanning and the weight trend are free. Paid plans add more AI photo scans (Free users can watch optional ads to earn extra ones) and, on Premium, workouts.
How accurate is photo logging?
A photo estimate is a starting point, not a lab result. Every portion comes back as a gram amount you can correct before you save it.
Can I use it offline?
Yes. Logging works without a connection and syncs later.
Can I delete my account?
Yes, any time, in Settings › Account › Delete account. You can also ask from the website.
Is ZMacros medical advice?
No. Its numbers are estimates to help you track. Talk to a doctor or dietitian about medical conditions, pregnancy or eating disorders.
