How to Switch from MyFitnessPal to Cronometer (2026 Guide)

Why People Switch from MyFitnessPal to Cronometer

The most common driver in our reader survey is accuracy. MyFitnessPal averaged ±18% MAPE in the DAI Six-App Validation Study (DAI-VAL-2026-01); Cronometer landed at ±5.2% on the same weighed reference meals. For a user who has been logging for six months and starts to doubt the daily total, that 13-point gap is the reason they look for an alternative.

Other common drivers:

• Wanting micronutrient tracking without paying for it (Cronometer’s free tier includes 84+ micros vs MyFitnessPal Premium’s ~12).
• Wanting USDA-aligned database entries instead of user-submitted defaults.
• Wanting an ad-free free tier.
• Wanting data export, recipe URL import, and custom biometrics on the free tier rather than paywalled.
• Clinical needs (PCOS, diabetes, kidney, autoimmune) that the MyFitnessPal feature set cannot serve.

Cronometer is the best search-and-log destination for any of these reasons.

Before You Migrate: What to Know

Cronometer is a different category of app from MyFitnessPal in three ways that are worth understanding before you switch:

1. Database structure: Cronometer’s database is one-twelfth the size of MyFitnessPal’s, but its first-result accuracy is materially higher because most entries come from USDA FoodData Central rather than user submissions. You will find fewer regional and small-chain restaurant entries; you will find more accurate whole-food entries.

2. Web-first power use: Cronometer’s web app at cronometer.com is the better surface for power use — denser diary, faster log workflow, full nutrient breakdowns. Mobile is fine but utilitarian.

3. No photo AI: Cronometer has no AI photo logging and no plans to add one. If photo AI is core to how you log, Cronometer is the wrong destination.

Step 1: Export Your Data from MyFitnessPal

Follow the export steps above in the frontmatter. The key constraints:

• Web only: The mobile app does not have a data export option in 2026. You must use myfitnesspal.com.
• Premium required: Data export is a Premium feature. If you are on free, the cheapest way to export is to upgrade for a single month ($19.99), export your data, and cancel.
• Email delivery: The export arrives as a ZIP file via email, usually within 6 hours of request, occasionally up to 24.

Once you have the ZIP, the relevant file is the food diary CSV. It contains every meal you logged, the food name, serving, calories, and macros.

Step 2: Import to Cronometer

Cronometer does not support direct CSV import from MyFitnessPal. The open-source community-maintained mfp-to-cronometer converter at github.com/cronometer-community/mfp-to-cronometer is the standard tool. It takes the MyFitnessPal CSV and produces a Cronometer-compatible JSON.

Once you have the JSON:

1. Sign in to Cronometer at cronometer.com.
2. Settings → Account → Import Data.
3. Upload the JSON.
4. Confirm the import preview — Cronometer will show you which days it will populate.
5. Run the import. Most days complete in under a minute.

After the import, check the “Needs Review” folder. This is where Cronometer puts foods it could not auto-map. For each entry, you can either:

• Pick the closest Cronometer USDA-aligned equivalent.
• Create a Cronometer custom food matching the MyFitnessPal entry.
• Skip the entry (the day will still show partial data).

Plan on 20-40 minutes of mapping work for an active logger with 12 months of history.

What You’ll Lose

Be honest with yourself about what does not migrate:

• Recipes: MyFitnessPal recipe entries do not import directly. You will need to rebuild them in Cronometer’s recipe editor — which is genuinely better, but is rebuild work nonetheless.
• Custom foods: Your MyFitnessPal custom foods need to be re-created. The converter handles macros but does not always pick up custom serving sizes correctly.
• Friend network: MyFitnessPal’s social features (feed, forums, friends) do not exist in Cronometer.
• Photo logs: If you used MyFitnessPal Premium’s Meal Scan feature, those logs do not transfer; only the resulting calorie/macro entries do.
• Streaks: Your in-app logging streak resets. The historical data is preserved, but the streak counter starts over.

What’s Better in Cronometer

• Accuracy: ±5.2% vs ±18% MAPE — the central reason to switch.
• Free micronutrients: 84+ micros free vs ~12 on MyFitnessPal Premium.
• USDA alignment: Most entries map cleanly to USDA FoodData Central, which means values are scientifically defensible.
• Free recipe URL import: Premium feature in MyFitnessPal, free in Cronometer.
• Free data export: You will not need to upgrade to migrate again later.
• Web app: Materially better for power use than MyFitnessPal’s web app.
• Calm interface: No ads on free, no aggressive upsell, no community feed pressure.

What’s Worse in Cronometer

• Restaurant chain coverage: MyFitnessPal still wins here, especially for non-US chains and regional players.
• Database breadth: Fewer entries overall. The first-result accuracy is better, but if you need to log something regional or obscure, you will sometimes need a custom entry.
• No photo AI: If you relied on Meal Scan, this gap is real.
• UX learning curve: Cronometer assumes the user wants to be precise. The diary view is denser and the goal-setting is more granular. Expect a few days of orientation.

First-Week Setup in Cronometer

Once the import is complete:

1. Set your goals under Settings → Profile. Cronometer’s goal-setting is granular — set daily calorie target, macro percentages or grams, and micronutrient targets if you have specific needs.
2. Calibrate your custom foods. Open the Needs Review folder and resolve the ten or twenty most-frequent entries first. The remaining can be resolved as you log them again.
3. Pin your most-used foods. Cronometer’s “favorites” feature is faster than MyFitnessPal’s recents — pin the 30-50 foods you log most often.
4. Try the recipe URL importer (free) for 2-3 of your most-used recipes. This is one of Cronometer’s strongest features.
5. Review the micronutrient dashboard. Even without specific goals, the dashboard gives you a sense of where your diet has gaps you may not have noticed before.

Bottom Line

Migrating from MyFitnessPal to Cronometer takes 30-60 minutes of active work plus the export wait. The trade-off you are making: better accuracy, better free-tier value, and worse restaurant coverage. For most users — especially anyone tracking for clinical reasons or running a measured cut — the trade is clearly worth it.

Step 1: Export from MyFitnessPal

1. Open MyFitnessPal on web at myfitnesspal.com — the mobile app does not allow export.
2. Sign in and click your username (top right), then Settings.
3. Scroll to the Export Data section and click Request Data.
4. Select the date range. For full history, use 'Beginning' to today.
5. Submit the request. MyFitnessPal will email a CSV ZIP within 24 hours, usually under 6 hours.
6. Download the ZIP from the email link. The relevant file is your food diary CSV.
7. Note: data export is a Premium feature. If you are on free, you will need to upgrade for one billing cycle to export.

Step 2: Import to Cronometer

1. Cronometer does not support direct CSV import from MyFitnessPal as of 2026.
2. Use the open-source 'mfp-to-cronometer' converter at github.com/cronometer-community/mfp-to-cronometer.
3. Run the script on your MyFitnessPal CSV — it produces a Cronometer-compatible JSON.
4. In Cronometer web (cronometer.com), go to Settings → Account → Import Data.
5. Upload the converted JSON and confirm the import preview.
6. Cronometer will replay each logged day, mapping foods to its USDA-aligned database where possible.
7. Foods without a clean Cronometer match will land in a 'Needs Review' folder — these will need manual mapping or recreation.

What you'll lose in migration

• Recipe history does not carry over directly — recipes will need to be rebuilt in Cronometer's recipe editor.
• Custom foods you created in MyFitnessPal will need to be recreated as Cronometer custom foods.
• User-submitted MyFitnessPal entries that do not match a Cronometer USDA-aligned equivalent will land in 'Needs Review.'
• Friend network and community features (forums, feed, shared recipes) do not migrate.
• Photo logs from MyFitnessPal Premium do not transfer.
• Exercise log entries can transfer via the JSON; some custom exercises may need re-entry.
