Diet App Scorecard: Monthly User Ratings for Popular Calorie Trackers

Sergey Oreshko - Co-founder and CEO of MyNetDiary

Which calorie tracking app do users rate highest? The Diet App Scorecard analyzes App Store reviews for top diet apps monthly. See the latest ratings.

Latest Snapshot

• Calo posted the highest rating in May 2026 at 4.66, with MyNetDiary close behind at 4.56 — the first month MyNetDiary wasn't on top. Calo's score carries a soft authenticity caveat worth monitoring.
• MyFitnessPal fell to 1.82, a fourth straight monthly decline since the March redesign and a new low for the scorecard. Review volume dropped by nearly half, but the remaining reviews were more negative, not less.
• Review authenticity concerns narrowed from six apps in April to three in May (Cal AI, BitePal, Calo), as MyFitnessPal, Municorn, and Simple returned to organic patterns.

What Is the Diet App Scorecard?

Choosing a calorie tracking app based on App Store ratings is harder than it should be. The displayed star rating is an all-time average that can span a decade, the auto-generated Review Summary often stays positive even when recent reviews turn negative, and the default "Most Helpful" sorting tends to surface older reviews instead of what's happening now.

Most "best calorie tracker" roundups don't solve that problem. They compare features, but not how those features hold up in daily use — how easy logging feels after a few weeks, how accurate the food database is for meals you actually eat, or what happens when you try to cancel. Those signals usually show up most clearly in recent user reviews.

MyNetDiary has been on the App Store since 2008. I'm Sergey Oreshko, the CEO, and I read competitor reviews constantly. The Diet App Scorecard exists because I believe users deserve a clearer view of what current users are actually experiencing before they download. As one of the apps analyzed, MyNetDiary should be evaluated with that context in mind.

Every month, we pull user reviews from the US App Store for calorie and food tracking apps ranked in the top 100 Health & Fitness category. We then run the same AI workflow and the exact same prompt on every app to filter duplicates and unrelated content, calculate that month's average review rating, and generate the review summary. Because every app is processed the same way, the analysis is impartial and avoids the subjective bias a human analyst would bring. We disclose the specific AI model for reproducibility, and publish the full prompt, and methodology on our methodology page.

If you prefer to do your own research, we recommend the five-minute review method: go to Ratings & Reviews on any app's store page, sort by Most Recent instead of Most Helpful, and read 20 to 30 reviews to spot patterns. For a step-by-step guide, see How to Find the Best Calorie Tracker App.

Across four months of the Diet App Scorecard, MyNetDiary's monthly review rating has held between 4.54 and 4.56 — the most consistent top-tier rating in the series. It led the scorecard in February, March, and April 2026, and ranked second in May, when Calo rated 4.66.

Calo received the highest average user rating (4.66) in the Diet App Scorecard for May 2026, with MyNetDiary close behind at 4.56 — the first month MyNetDiary wasn't on top. Calo's score comes with a soft authenticity caveat worth monitoring. May was also the month MyFitnessPal's redesign backlash reached a fourth straight decline, falling to a scorecard-low 1.82, while BitePal's rating jumped a full star even as its billing complaints continued.

What changed this month

Compared to April: MyFitnessPal kept falling (down to 1.82), Calo edged past MyNetDiary for the top rating, review authenticity concerns narrowed from six apps to three, and Foodvisor joined the scorecard.

Which Apps We Analyze

We don't maintain a fixed list of apps chosen by our editorial team. On the last day of each month, we check the US App Store's top 100 apps in the Health & Fitness category and identify all apps whose primary function is calorie tracking, food tracking, or diet tracking. We exclude apps that aren't primarily diet or calorie tracking — workout-only trackers, step counters, meditation apps, period trackers, and the like.

The scorecard adapts to the market. If a new app rises in popularity, it enters the analysis. If an app falls out of the top 100, it exits. If an app is popular enough to rank in the top 100 — whether it got there organically or through paid marketing and advertising — it belongs in the analysis. The market decides which apps are relevant, not us.

Some of the most interesting findings come from this approach. Apps that spend heavily on advertising to reach the top 10 in downloads but receive poor user reviews once people actually use them reveal a gap between marketing-driven popularity and actual user satisfaction. That gap is exactly what the scorecard is designed to surface.

What Each Monthly Scorecard Includes

Each monthly installment covers every qualifying app with:

• Filtered average rating. The average star rating recalculated from that month's reviews only, after removing duplicates and unrelated reviews. This is a review rating for the current month — not the all-time star rating the App Store displays.
• Review summary. A 100 to 120 word AI-generated summary of what users said, representing positive and negative sentiment proportionally. Each app's summary is independent and doesn't compare to other apps.
• Authenticity assessment. Whether each app's review patterns appear organic, bimodal, or suspicious, as assessed by the AI using the same analysis prompt applied to every app.
• Comparison table. All apps side by side with ratings, top praise, top complaint, and authenticity, listed in download ranking order.
• Trend analysis. Cross-app observations about the themes that dominated reviews that month.

Which App Might Be Right for You?

There isn't one best calorie tracking app for everyone. Different apps appeal to different users. The Simple app often resonates with people who want intermittent fasting structure and a coaching-oriented experience. Some fitness-focused users are drawn to MacroFactor's more analytical style, though reviews also point to execution issues. MyNetDiary is most often praised for ease of use, free barcode scanning, broad nutrition detail, and a staff-verified food database. The purpose of the scorecard is not to choose for you, but to show which strengths and tradeoffs users are reporting right now.
