Does copying the app copy every meal?

Not necessarily. Platform guidance describes limits and provider-dependent data. Check the actual account and sample records on the new device.

Should I use my store email to sign into the diary?

Use the in-app sign-in method associated with the existing diary. The store account used for billing may be a separate identity.

Does restoring PRO also restore food history?

An entitlement check does not establish that meal history was recovered. Verify purchases and diary records separately.

Can I erase the old phone after the app opens?

First verify the records and access you need and resolve any gaps. Opening the app alone is not a complete migration check.

Does CalQuest promise automatic cross-platform history transfer?

No such promise is made here. Check the actual account and records, preserve access to needed information and ask support about your specific move.

Changing phones with a calorie tracker: account and diary checks

Food tracking guides

By CalQuest teamPublished 26 May 2026Updated 6 November 20265 min read

The quick answer

Before changing phones, identify the calorie-tracker account, the store account used for purchases and the records you need to see on the new device. Follow the phone maker's transfer guidance, then check the actual diary rather than assuming a copied app includes every meal. Purchase access and food history are separate checks. Keep the old device available while you verify dates, sample entries, photos and repeat foods, and ask support about anything missing.

Record the identities involved before starting

A phone can contain several different identities: the account used to download apps, the account used for purchases and the account you sign into inside a food tracker. They may use the same email address, but they serve different roles. Before changing devices, note which app and developer you use, how you sign in, and which store or provider billed any subscription.

Choose a few records you expect to recognise on the new phone. Include yesterday's breakfast, an older dinner, a photo entry and a familiar food you reuse. Write down their dates and distinguishing details without collecting unnecessary private material. This is a verification sample, not a substitute for a backup. Keep the original device accessible while you check the outcome.

Use the platform transfer route without assuming app coverage

Apple provides iCloud transfer instructions and guidance for information missing after a restore. Its support notes that some third-party app data may need to download again from the provider. Google describes transferring apps and certain app data, and explicitly excludes data from apps that do not use Android backup. Platform transfer is therefore a starting point, not proof that every diary field will appear.

Follow the guidance for your actual old and new phones. If you are changing operating systems, do not treat same-platform transfer instructions as a promise for that move. Check the food tracker's own account and data instructions too. Keep any unresolved question specific: which record, which account, which device and which action have you verified?

Check the new phone in separate passes

A successful installation, purchase check and diary check answer different questions. Record each result rather than using a single welcome screen as confirmation that the move is complete.

What to verify after moving a food tracker to a new phone
Check	Evidence to inspect	What it does not prove
App identity	Correct app, developer and current listing	The old account is signed in
In-app account	Expected sign-in method and account details	A store purchase is active
Purchase access	Correct billed account and displayed entitlement	Meal history has transferred
Diary sample	Expected dates, foods, portions and notes	Every historical record is complete
Photo sample	An intended image opens	Every photo is available
Repeat foods	Expected Recent/Favourites items where supported	A recipe or full archive was migrated

Inspect a sample before recreating missing meals

Open the dates in your sample and compare the meaning of the entries. Check food names, amount, units, nutrition and notes you rely on. If a photo or older record is absent, note that specific gap. Do not immediately retype the meal or create a second account to make the diary look complete. Those changes can make the original account question harder to resolve.

If only some information appears, check the current account and any restore or download status the platform shows. Ask the developer about the unresolved record and what recovery routes are supported. This guide does not guarantee a waiting period, automatic sync or migration result. A few correct entries are useful evidence, while a full-history guarantee requires more than a sample.

Treat CalQuest access and records as separate questions

CalQuest supports camera/gallery meal photos, editable estimates, optional notes, manual known nutrition and Recent/Favourites. Those capabilities do not establish how every field will move between phones. Its policy describes account logs and cloud photo storage, but this guide does not promise complete migration, a device backup, direct competitor import or CSV export.

Check purchase access separately if you use optional PRO. CalQuest's English app text includes a restore-purchases action, but restoring an entitlement is not evidence that meal records have been restored. Free photo energy remains limited and ads are part of the free experience. If a purchase or history result is unclear, retain the receipt or sample details relevant to that question and use the official support route.

A change-phone checklist with a meal sample

Imagine moving your usual breakfast diary to a new phone. Confirm the account first, compare an existing breakfast and its photo, then check a repeat-food entry. Only after that should you rely on the new setup for the next meal.

Record the correct app, in-app sign-in method and billed store account.
Identify a small sample of recent and older meals, including a photo.
Use the current transfer guidance for the actual phone combination.
Check the new device account before judging missing records.
Verify purchase access, diary entries, photos and repeat foods separately.
Keep the old device and needed records available while support resolves any gaps.
