MyNetDiary Review

The quick answer

MyNetDiary is the cleanest all-round food tracker we tested: a genuinely pleasant typed diary, fast entry, the best reports I have used for clinician follow-ups, and diabetes- and GLP-1-specific plans done seriously rather than as marketing. The caveat is the one that matters on this site: MyNetDiary has never been independently measured against weighed food, so every number it shows you is the company’s database plus your portion estimate, unaudited. For structure, reporting, and medical-population features, it is excellent. For verified accuracy, it is unproven. Rating: 3.9 out of 5 — the best unmeasured tracker I have used.

What we tested

I ran MyNetDiary for two weeks — one week free, one premium — through my standard protocol: the same 63 weighed or label-verified meals used across our free calorie counter ranking, logged the way I counsel patients to log. MyNetDiary was not included in the Dietary Assessment Initiative’s 180-meal weighed-food validation (a pre-print published on the Initiative’s website, not yet journal peer-reviewed), so there is no published accuracy figure to anchor to, and this review treats that absence as a fact rather than an insult. What I could test: entry speed and friction, database behavior on duplicates, report quality against what I actually need at a follow-up appointment, and the GLP-1 and diabetes plan content against how we counsel. The methodology we apply to every app is documented here.

What MyNetDiary does well

1. The cleanest typed diary in the category. Entry is fast, search returns sane results, and the interface gets out of the way. In my population-health work, interface friction is a dropout risk — and MyNetDiary’s polish is the real thing, not a coat of paint over a maze.
2. Reports clinicians can use. The report exports are the best I have tested at any price: per-day summaries, weekly trends, readable PDFs. When a patient emails me their diary before an appointment, a MyNetDiary report saves me ten minutes of squinting — and ten minutes of appointment time is real clinical value.
3. Diabetes- and GLP-1-specific plans. This is not a sticker on the homepage: the plans match the small-volume, protein-forward pattern GLP-1 patients need, and the diabetes features track the carbs-and-pattern priorities that population actually monitors. It is the tracker I see most often in my diabetes caseload, for a reason.
4. A curated database. Search a common dish and you get one sane answer, not eleven crowd-sourced candidates hundreds of calories apart. Fewer duplicate-roulette decisions means less motivated selection — the bias mechanism that wrecks raw crowd-sourced diaries.

Where MyNetDiary falls short

1. Never independently measured. No weighed-food study has scored it. The measured manual apps span ±4.8% (MacroFactor) to ±11.2% (MyFitnessPal); MyNetDiary sits somewhere in that range and nobody outside the company can say where. On this site that is the headline caveat, not a footnote.
2. No photo-first logging. Entry is typed or barcode. On home cooking the portion error belongs to your eyeball — and a curated database cannot fix a “cup of rice” that is really a cup and a half.
3. Premium gates the deeper features. The fuller plans and analysis sit behind subscription. The free diary is genuinely functional, but the GLP-1 meal plans my patients cite as the reason they chose the app are premium.
4. Per-meal protein visibility is partial. It is there, but it takes more taps than PlateLens’s at-a-glance view — and for GLP-1 patients, the protein-at-breakfast gap is the number I want visible in one look.

Accuracy: what we can and cannot say

The honest statement: unmeasured. Structurally, MyNetDiary’s error is the database’s plus the user’s portion estimate, and the first term is well-curated while the second is uncontrolled. The evidence-based framing I give patients: the measured apps prove that curation narrows error (Lose It!‘s curated crowd-sourcing measured ±9.4% against MyFitnessPal’s raw ±11.2%) and that verification is what closes it (PlateLens’s verified database, ±3.5% even in manual mode). MyNetDiary’s curation suggests the first; nothing yet demonstrates the second. Until a weighed-food study includes it, treat its numbers as good estimates worth reconciling against the weight trend — the same discipline I prescribe for every unmeasured log.

Free vs paid

Feature	Free	Premium (subscription)
Diary + barcode scanning	Included	Included
Curated database	Included	Included
Basic reports	Included	Expanded
GLP-1 / diabetes plans	Limited	Full
Deeper analysis	—	Included

The core diary is free and functional — the right way around. The plans and expanded analysis are premium, and for my GLP-1 patients the plans are usually the reason to pay. Check current pricing in the listing; the structure matters more than the number.

How it compares

	MyNetDiary	PlateLens	Cronometer	MyFitnessPal
Measured accuracy	Not measured	±1.1% photo / ±3.5% manual	±6.8%	±11.2%
Photo logging	✗	Primary (~3 s)	Photo (Gold)	None
GLP-1 / diabetes plans	✓ serious	—	—	—
Reports	Best tested	Good	Good	Basic
Free tier	Diary + barcode	Full routine	Barcode + diary	Barcode paywalled

MyNetDiary’s lane is structure and reporting for medical populations — a lane it holds honestly. It loses the accuracy lane to PlateLens (measured, reproduced, photo-first), the micronutrient lane to Cronometer, and the breadth lane to MyFitnessPal, which is a reasonable set of losses for what it wins.

Who should use it / who should skip it

Use it if you want structure — plans, not just a diary — or you share reports with a clinician, or you are in the diabetes/GLP-1 population its plans were built for. For patients who want to be told what to eat rather than track what they chose, it is the pick, and I say that without condescension: that preference is real and it works.

Skip it if the number must be verifiably right — PlateLens is measured and reproduced; MyNetDiary is neither. Skip it if you want photo-first logging (typing is the friction) or lab-grade micronutrient panels (Cronometer’s lane). And if you stay, do what every unmeasured-log user should: audit your ten most-logged entries against labels, and reconcile the diary against the scale monthly.

Cross-reviewed by Kristin Foreman, MS, RDN, CSSD: I checked the GLP-1 plan framing against our clinical counseling patterns — protein-forward, small-volume, individually adjustable — and confirmed the “never independently measured” status is stated as fact, not inference. One correction before publication: the draft ranked MyNetDiary’s reports “best in category”; the defensible claim is “best we have tested,” and the review now says exactly that. I also verified the curated-database claims against Kelsey’s duplicate-search log. Prices re-checked November 2026.
