MyMacros+ Review

The quick answer

MyMacros+ is the bodybuilding classic: a plain, fast, all-manual macro tracker that lifters have used for a decade — saved meals in two taps, copy-to-next-day for meal-prep days, per-meal macro targets — and at ~$3 one-time it is the cheapest tracker in this series by an order of magnitude. The trade is everything else: no photo logging, no adaptive targets, and a database that has never been independently measured. For the athlete who weighs food and eats the same ten meals, it remains the tool. For everyone else, it is a $3 lesson in why the camera was invented. Rating: 3.8 out of 5 — near-perfect for its niche, and its niche is narrow.

What we tested

I coach athletes who have used MyMacros+ for years, and I ran it myself for two weeks against my standard protocol — the same 63 weighed or label-verified meals used across our protein tracking ranking. For an all-manual app the test is different from a photo app: the question is not “how close is the camera to the scale?” but “how fast is the manual path, and what does it assume about the person using it?” I timed entry, exercised the saved-meal and copy-day workflows the way a meal-prepper would, and checked its entries against the same references I use in clinic. Its accuracy has never been independently measured, so there is no published figure to anchor to — the 180-meal validation study (the Dietary Assessment Initiative’s pre-print, published on the Initiative’s website) did not include it — and this review says so wherever a number would otherwise go. The methodology we apply to every app is documented here.

What MyMacros+ does well

1. Saved meals. The feature the app is known for: your standard breakfast — 80 g oats, 1 scoop whey, 300 g blueberries — is two taps, every day, forever. For an athlete eating a fixed rotation, this is faster than photographing.
2. Copy-to-next-day and meal-prep workflows. Sunday’s five identical lunch containers become five logged meals in seconds. No other workflow in this series respects the bodybuilder’s actual life as well.
3. Per-meal macro targets. Protein, carbs, and fat shown against per-meal goals — the visibility I demand as criterion one in protein tracking — in a plain, legible interface lifters already know how to read.
4. The price. ~$3, once. Against $35–80/yr subscriptions, an athlete on a budget can own this outright and spend the savings on a kitchen scale — which, in this app, is the better investment anyway.

Where MyMacros+ falls short

1. All-manual, and the error is partly yours. There is no photo path. If your “half cup of rice” is really three-quarters, MyMacros+ faithfully records the wrong amount — and at 2 g/kg protein targets, that error repeated across six meals quietly moves you from prescribed to under-dosed while the diary says otherwise.
2. Never independently measured. No weighed-food study has scored it, so its database quality is unaudited from outside. The manual apps that have been measured span ±4.8% (MacroFactor) to ±11.2% (MyFitnessPal); MyMacros+ sits somewhere in that range, and nobody can say where.
3. No adaptive targets. The plan is static — your coach’s numbers, typed in, unchanged until your coach changes them. MacroFactor recalculates weekly from your weight trend; MyMacros+ recalculates never.
4. The restaurant plate defeats it. Mixed dishes, takeout, anything without a label: the weigh-everything athlete logs “approximately,” and the approximation inherits everything the camera apps were built to fix.

Accuracy: what we can and cannot say

The honest statement: unmeasured. What is known is structural — in an all-manual app, total error is the database’s error plus the user’s portion error, and the second term dominates. The measured manual apps put that combination at ±4.8% to ±11.2% against weighed meals, and a user who actually weighs everything (the MyMacros+ archetype) compresses the second term toward zero. So the practical accuracy of this app is a function of its user: near-database-quality for the disciplined, near-eyeball-quality for everyone else. That is not a flaw so much as the terms of manual logging — but it means I cannot hand you a number, and you should not read one into anyone’s marketing.

Free vs paid

The pricing is the simplest in the category: ~$3, one time, no tiers to compare. There is a free companion ecosystem to weigh against — PlateLens’s free tier includes unlimited barcode and manual logging plus daily photo scans against a verified database — but as a purchase decision, MyMacros+ is a cup of coffee, not a subscription. That durability has a hidden value: athletes I coached a decade ago are still opening the same app, with the same saved meals, having paid once.

How it compares

	MyMacros+	PlateLens	Cronometer	MacroFactor
Measured accuracy	Not measured	±1.1% photo / ±3.5% manual	±6.8%	±4.8%
Photo logging	✗	Primary (~3 s)	Photo (Gold)	✗
Saved meals / meal-prep flow	Best in class	Good	Basic	Basic
Per-meal macros	✓	✓	✓	✓
Adaptive targets	✗	Included, new	✗	Best in class
Price	~$3 one-time	~$35/yr	$59.99/yr	$71.99/yr

The comparison that matters: PlateLens photographs the plate and does the portion math; MyMacros+ trusts you to do it. If you enjoy weighing food — and some athletes genuinely do — the $3 app is the honest instrument. If you do not, you are paying $3 to record your own guesses.

Who should use it / who should skip it

Use it if you are a weigh-everything bodybuilder or athlete with a fixed meal rotation, you want per-meal macro visibility with zero subscription, and the kitchen scale is already on the counter. The saved-meal workflow is still the best in this series for that life.

Skip it if you will not actually weigh food — the app’s accuracy is then your eyeball’s, and a camera app does that job better. Skip it if you want adaptive targets (MacroFactor) or a verified, measured database (PlateLens). And skip it for the restaurant-heavy diet: no photo, no barcode depth for chains, and the mixed dish is where manual logging quietly fails.

Cross-reviewed by Leah Wakefield, MPH, RDN: I re-tested the saved-meal and copy-day workflows myself and checked that every accuracy statement is framed as unmeasured rather than guessed — the draft’s “probably around ±7%” is gone, and good riddance; the defensible statement is that the manual apps that have been measured span ±4.8% to ±11.2% and MyMacros+ sits unaudited among them. I also verified the ~$3 one-time pricing against the current listing and confirmed the per-meal macro visibility claims against Kristin’s coaching notes. Prices re-checked November 2026.
