• The unique energy expenditure calculation detects changes in your metabolism

• Weekly check-ins keep you on track toward your goals

The result? You better understand your body’s needs and can successfully reach and sustain your goals without stress.

THE BEST MACRO TRACKER TOOLS

• The fastest macro tracker on the market with tools like barcode scan and custom foods
• Verified food database, so you can trust the accuracy of the foods you log

AN EMPOWERING, SUSTAINABLE APPROACH

MacroFactor’s robust nutrition coach algorithm will make appropriate adjustments to your calorie and macro targets based on what you log, regardless of how close you came to hitting your targets from the previous week. The algorithms don’t function any worse if you deviate from your macro targets.

This means that unlike other nutrition coach apps, you don’t have to eat like a robot or perfectly adhere to your macro targets in order to get your weekly coaching check-in and an appropriate calorie adjustment.

You’ll never see warnings, red numbers, or shaming when you go over your calorie or macro targets, unlike in other macro tracker apps.

Instead, MacroFactor’s macro tracker and nutrition coach aim to empower you with the guidance and tools you need to reach your goals without stress or rigidity.

Great app, especially love that I don't have to enter exercise calories, and it's based on scientific evidence. tracking is easy once you get the hang of it. my only request would be to rethink the ability to view past entries - for example, ia monthly view where I can click on a day to get a dashboard similar to what I can see for today, or summary of multiple macros, nutrients, with weight, etc? as is, the looking back is a bit clunky.

It's an amazing app, the best in its category. My only gripe is the subscription model. I would gladly pay the equivalent of a handful of years at once to get lifetime access. I know everyone else is doing it, and this one is cheaper per month, but for me part of a premium experience is also to buy the thing once and for all. At least the annual discount is pretty interesting.

All of our expenses to run the app are monthly. A one-time payment would set up a perverse incentive where we'd benefit most from people only using the app for a couple weeks, and we'd lose money on loyal, long-time users. As it is, our incentives are aligned with users – we benefit when we keep users happy enough to stick around for a long time.

this app changed my life. It is probably the only app I can say that about. I lost 40 kg (around 88 pounds) that I carried for 25 years and I have kept it off for two years now. It's easy to use and I'm still tracking. It doesn't take much effort to track. just using this app for like a day is eye opening, I had no idea how many calories my bad habits were making me eat and this app was a dose of truth right out the gate.
