How to Switch from Cronometer to MyFitnessPal (2026 Guide)

Why People Switch from Cronometer to MyFitnessPal

This is the less common direction in our reader survey, but it does happen. The drivers are usually:

• Restaurant frustration: Cronometer’s restaurant coverage, especially for non-US chains and regional players, forces frequent custom-entry creation. Users who eat out 4+ times a week burn out on this.
• Photo AI: MyFitnessPal Premium has Meal Scan; Cronometer has none. If you want photo-first logging in the same app as your search-and-log, MyFitnessPal is the only mainstream search-and-log app that has it.
• Community: Some users miss the social feed, forums, and shared recipes.
• Familiarity: Users coming back to tracking after a hiatus often default to MyFitnessPal because they used it years ago.

The trade-off is real and honest: you are giving up accuracy and micronutrient depth to gain breadth. We are not going to pretend otherwise.

Before You Migrate: What to Know

Cronometer scored ±5.2% MAPE in the DAI Six-App Validation Study (DAI-VAL-2026-01); MyFitnessPal scored ±18%. The accuracy gap is real and persistent, and no amount of feature-richness on MyFitnessPal closes it.

If you are migrating because of restaurant frustration, consider whether the right answer is actually to use both apps — Cronometer for groceries and home cooking, MyFitnessPal selectively for restaurants. Some users find this hybrid approach gives them the best of both.

Step 1: Export Your Data from Cronometer

Cronometer’s export is genuinely free and immediate — one of the reasons it is the most respected app in the category for power users.

1. Open cronometer.com on web (export is web-only).
2. Settings → Account → Export Data.
3. Select format: CSV.
4. Date range: All time.
5. Type: Food Diary.
6. Click Export — CSV downloads directly.

Optionally, also export your custom foods and recipes (separate exports). These are useful if you want to manually reconstruct them in MyFitnessPal.

Step 2: Import to MyFitnessPal

MyFitnessPal’s import is the bottleneck. There is no guided Cronometer importer in 2026, and the generic CSV importer is finicky about column headers.

The reliable path:

1. Use the open-source cronometer-to-mfp converter at github.com/calorie-tools/cronometer-to-mfp to reformat the Cronometer CSV into MyFitnessPal-compatible columns.
2. Sign in to myfitnesspal.com.
3. Settings → Import.
4. Upload the reformatted CSV.
5. Review the “Pending” folder — foods that did not auto-match against MyFitnessPal’s database land here.
6. For each pending entry, pick the closest MyFitnessPal database hit, create a custom food, or skip.

MyFitnessPal Premium is required for CSV import. If you do not have it, upgrade for one billing cycle ($19.99/mo) for the migration and cancel.

Plan on 30-60 minutes of cleanup work for an active logger with 12 months of history. The cleanup is more painful than Cronometer-to-MyFitnessPal because Cronometer entries are USDA-precise and MyFitnessPal’s database does not always have a clean equivalent.

What You’ll Lose

• Most of your micronutrient depth: 84+ micros in Cronometer free → ~12 in MyFitnessPal Premium.
• USDA precision: Cronometer’s USDA SR Legacy entries map approximately to MyFitnessPal but with looser values.
• Recipe history: Cronometer recipes do not transfer — rebuild in MyFitnessPal.
• Custom foods: Will need re-entry with adjusted serving sizes.
• Biometric data: Cronometer Gold’s blood glucose, ketones, blood pressure tracking does not exist in MyFitnessPal.
• Oracle target history: Cronometer-specific.
• Free data export: MyFitnessPal export is Premium-only.
• Accuracy: ±5.2% → ±18% MAPE.

What’s Better in MyFitnessPal

• Database breadth: 14M entries vs 1.2M.
• Restaurant chain coverage: Best in the category, especially US/UK chains.
• Barcode coverage: Stronger international coverage.
• AI photo logging: Meal Scan on Premium.
• Community features: Feed, forums, shared recipes.
• Onboarding ease: Familiar interface for users returning from a hiatus.
• Integrations: Slightly broader third-party integration ecosystem.

What’s Worse in MyFitnessPal

• Accuracy (the central trade-off).
• Free-tier value: Cronometer free includes recipe import, micros, and export — all paywalled in MyFitnessPal.
• Ad load: MyFitnessPal serves ads aggressively in 2026.
• Database verification: User-submitted entries dominate; verification badge exists but is not default.
• Web app density: Cronometer’s web app is materially better for power use.
• Pricing: $79.99/yr Premium vs $54.95/yr Cronometer Gold.

First-Week Setup in MyFitnessPal

1. Set up your goals under Goals.
2. Resolve the Pending folder — at minimum, the top 30 most-frequent imports.
3. Pin your most-used foods to make logging fast.
4. Set the verified-entry filter to default if you have Premium.
5. Connect Apple Health, Google Fit, Garmin, or Fitbit under Apps.
6. Try Meal Scan if Premium, with realistic accuracy expectations.

Bottom Line

Cronometer-to-MyFitnessPal is the trade of accuracy for breadth. If your reason to migrate is restaurant coverage and you accept the ±18% noise band, this is fine. Many users we surveyed end up keeping Cronometer as their primary tracker and using MyFitnessPal selectively for restaurants. That hybrid approach often produces a better outcome than a clean migration in either direction.

Step 1: Export from Cronometer

1. Open Cronometer on web at cronometer.com (export is web-only and free).
2. Sign in and go to Settings → Account → Export Data.
3. Select export format: CSV.
4. Choose date range — 'All time' for full history.
5. Select 'Food Diary' as the export type.
6. Click Export. The CSV downloads directly — no email wait.
7. Optionally also export your custom foods and recipes (separate exports under the same menu).

Step 2: Import to MyFitnessPal

1. MyFitnessPal does not have a guided Cronometer importer.
2. MyFitnessPal accepts CSV imports through the web app at myfitnesspal.com → Settings → Import.
3. The MyFitnessPal importer is finicky — column headers must match its expected format.
4. Use the open-source 'cronometer-to-mfp' converter at github.com/calorie-tools/cronometer-to-mfp to reformat the CSV.
5. Upload the reformatted CSV to MyFitnessPal.
6. Foods that do not auto-match land in 'Pending' — review and confirm or remap.
7. MyFitnessPal Premium is required for CSV import.

What you'll lose in migration

• Most of Cronometer's free 84+ micronutrient data does not transfer — MyFitnessPal Premium tracks ~12 micros total.
• Cronometer's USDA-aligned database entries map approximately to MyFitnessPal but with looser precision.
• Custom foods will need manual re-entry for serving sizes and exact macros.
• Recipe history does not carry over — rebuild in MyFitnessPal recipe editor.
• Cronometer's biometric data (Gold tier — glucose, ketones, BP) does not transfer.
• Oracle target history is Cronometer-specific and does not exist in MyFitnessPal.
