Switch from Cronometer to Bento Bunny

Why People Are Leaving Cronometer

Let's be fair to Cronometer first: it has the most accurate micronutrient data in the business, built on lab-verified sources. If you're managing a clinical condition that requires tracking 80+ micronutrients, Cronometer is genuinely hard to beat — and our Cronometer review says so.

But most people don't need 80 micronutrients. They need to know their calories and macros, fast, every day, without friction. Cronometer's logging flow is precise but slow — search, select, weigh, confirm — and the features that speed it up increasingly sit behind Gold, which runs around $50 a year as of mid-2026. If you've realised you're spending lab-grade effort on a what-did-I-eat-today problem, this guide is the way out. (Still deciding? See Bento Bunny vs Cronometer.)

The Good News: One-Tap Import

Bento Bunny has a one-tap importer built specifically for Cronometer, the same first-class treatment as MyFitnessPal. Your years of carefully weighed entries don't get abandoned — they come with you.

Step 1: Export Your Cronometer Data

1. Sign in at cronometer.com on a computer — the full export lives in the web app.
2. Go to Settings → Account → Export Data.
3. Choose the categories you want — food and recipe entries (the important one), plus biometrics and exercise if you track them — and your date range.
4. Download the CSV files. They generate immediately; no waiting on an email.

Step 2: Run the Import in Bento Bunny

1. In Bento Bunny, open Settings → Import Data and choose Cronometer as the source. The export instructions are shown inline so you don't have to switch apps.
2. Pick your exported CSV file.
3. Review the preview: Bento Bunny shows the date range, the number of entries found, and how many would duplicate meals you've already logged. Nothing imports until you confirm.
4. Tap Import. Entries save in batches with a live progress bar — most multi-year exports finish in under a minute.

The same smart deduplication as the MyFitnessPal importer applies: overlapping entries are fingerprinted by timestamp, food name, and calories, and skipped automatically, so re-running an import never doubles your data.

Step 3: Carry Your Goals Over

Note your Cronometer targets before you go: your energy target, your macro targets (Cronometer lets you set them by ratio or grams), and your goal weight. Enter the same numbers in Bento Bunny's goal settings. If Cronometer has been syncing your weight to Apple Health, that history flows into Bento Bunny automatically.

What Maps to What

• Date and meal grouping → preserved in your Bento Bunny food log.
• Food name, calories, protein, carbs, and fat → imported directly.
• The long micronutrient tail → this is the honest limitation: Bento Bunny tracks the macros people act on daily, not all 80+ micronutrients. If full micronutrient tracking is a hard requirement, Cronometer remains the better tool for that job.
• Custom recipes → the meals you logged from them import; the recipe definitions don't. Photograph a favourite once and it's fast to re-log.
• Biometrics → sync via Apple Health rather than the CSV.

When to Cancel Cronometer Gold

Run both apps in parallel for a few days first — your Gold subscription stays active until the end of the billing period regardless, so there's no refund advantage to cancelling early, only the risk of an auto-renewal at around $50 a year (as of mid-2026) if you forget.

If you subscribed through the App Store: Settings → [your name] → Subscriptions, tap Cronometer, Cancel Subscription. If you subscribed on cronometer.com, cancel from your account settings on the website. Your receipt email tells you which channel billed you.

What You Gain on the Other Side

Speed, mostly. Cronometer optimises for precision; Bento Bunny optimises for the habit actually surviving. Point your camera at your plate, the AI identifies the food and estimates portions, one tap and it's logged. On iOS 26 and later the AI runs on-device with Apple's Foundation Models — photos never leave your phone, and it works offline. Barcode scanning is free. And your data exports back out whenever you want, in the same spirit as Cronometer's own export: your data is yours.

Ready to Make the Switch?

Export, import, set your targets — about ten minutes end to end, with your full history intact. Then logging takes a photo instead of a food scale.
