Years of meals, weigh-ins and streaks are the main reason people stay with a calorie counter they no longer enjoy. Starting from zero feels like losing all of that. It doesn’t have to be: most diaries can be taken with you, and the ones that can’t can still be read.
Before you start: don’t delete anything
Cancel a subscription if you like, but keep the old account until your history is safely in the new app. A deleted account usually takes its diary with it, and an export is often only available while you can sign in.
Step 1. Export your diary
Look for “Export data”, “Download data” or “Reports” in the app’s settings — or on its website, where exports often live. What you want is a spreadsheet (CSV) of your food log, and your weight history if there is a separate file.
- MyFitnessPal. The diary export is made on the website and is a Premium feature; check MyFitnessPal’s help pages for the current steps.
- Cronometer. In the account settings, under account data, choose “Export data”, a date range and the servings (your food log).
- Lose It!, FatSecret, Yazio and others. Exports exist in some form for most of them, often on the website; menus change, so search the app’s help for “export”.
No export, or it costs money? Screenshots work too. Scroll through your diary and take a screenshot of each day — the new app can read them.
Step 2. Import it
A good importer should do four things:
- Show a preview of what it understood before writing anything.
- Let you skip days you have already logged in the new app.
- Never add the same meal twice if you import the same file again.
- Bring your weight history along, not only food.
Step 3. Give the new app two weeks
Old habits are built around old screens. Log everything for two weeks, even roughly, before you judge. If the new app adapts targets to your data, your imported history gives it a head start.
What to look for in a new tracker
- Logging that takes seconds — a photo, a sentence, your voice — so you keep doing it.
- More than calories: protein, fibre, vitamins and minerals against your own norms.
- Targets that follow what you really burn, not only a formula.
- A free plan good enough to try it properly.
We compare foodoo with the big names side by side — honestly, starting with what each does better — on our comparison pages.
foodoo reads exports from MyFitnessPal, Cronometer, Lose It! and any CSV, or screenshots of any app’s diary. Upload the file from a computer through a one-time link or pick it on your phone; you see a preview, nothing is written until you confirm, days already logged can be skipped, and importing the same file twice adds nothing. On iPhone it can also bring in meals other apps wrote to Apple Health.
