For a birthday reminder backup before switching apps, do not begin by uninstalling the old app. Keep the original list unchanged, identify where each birthday is stored, make a current device backup, and create a portable copy wherever the source supports one.
A full iPhone backup and an exported birthday list are not interchangeable. The backup is a rollback option. The export is what you can inspect or move. You may need both, plus a short worksheet for notes and reminder settings that neither system transfers.
Record a baseline before changing anything
Open the old app and write down a few facts about the current list:
- Total number of people or occasions.
- The next three upcoming birthdays.
- One birthday later in the year.
- One record with a birth year.
- One record without a birth year.
- One record with a note or gift idea.
- One person with a customized reminder.
These become your control records. They help reveal a partial import that otherwise looks successful.
Avoid cleaning duplicates or editing dates during this step. If you change the source while also testing the destination, it becomes difficult to tell whether a mismatch came from the migration or your edits.
Identify where the birthday records actually live
A birthday visible in an app may still be owned by Contacts, Calendar, or the app’s private database.
| Source | Portable copy | Likely limitation |
|---|---|---|
| iPhone Contacts | Exported contact cards | Does not include settings created only inside a birthday app |
| Regular calendar events | Calendar export, if supported | May not contain relationships, notes, or birthday-specific alerts |
| Birthday app database | The app’s documented export, if available | Format and included fields vary by app |
| App with no export | Manual worksheet plus device backup | Manual entry may be required in the new app |
Check one person in the old app against their contact card. If changing the contact changes the app, Contacts may be the source. If the app keeps its own notes, gift ideas, favorites, or reminders, those fields are app data even when the original date came from Contacts.
This distinction determines what you need to preserve. The detailed guide to backing up and exporting birthday reminders covers the separate procedures for app data, Contacts, and regular calendars.
Export birthdays held in iPhone Contacts
Apple lets you export some or all contacts from an iPhone:
- Open Contacts.
- Tap Lists at the top left.
- Touch and hold the relevant list.
- Tap Export.
- Select the fields to include, making sure the birthday field is selected.
- Tap Done, then choose a protected place to save the exported contact cards.
An exported contact can contain phone numbers, addresses, email addresses, and notes as well as a birthday. Treat the file as personal data. Avoid leaving it in a public link, shared folder, or unprotected email account.
A Contacts export does not prove the new birthday app can read every field. Test a few contact cards before relying on a bulk import.
Make a device backup for rollback
A device backup protects a different layer. Apple says iCloud Backup includes downloaded-app data that is not already syncing through iCloud, although individual apps can be excluded.
To make and inspect an iCloud backup:
- Open Settings and tap your name.
- Tap iCloud > iCloud Backup.
- Turn on Back Up This iPhone if needed.
- Tap Back Up Now.
- Wait for completion and confirm the latest backup time.
- Tap the entry for this iPhone and confirm the old birthday app has not been excluded.
You can also create a computer backup through Finder or the applicable Apple device-management software.
This backup does not import records into a different app. It can help restore the previous device state if the source data is lost. Treat it as a safety net, not as the migration file.
If you are changing phones rather than apps, use the separate guide to transferring birthday reminders to a new iPhone.
Capture fields an export may omit
Before importing anything, build a small migration worksheet. Use only fields you genuinely need:
| Field | What to check |
|---|---|
| Name | Preserve the spelling used to identify the person |
| Month and day | Confirm the core birthday date |
| Birth year | Keep it if known; do not invent one |
| Relationship | Copy it if the new app supports it |
| Reminder schedule | Record each useful lead time and alert time |
| Practical note | Keep concise context such as a time zone or gift idea |
| Source | Note whether the record came from Contacts or the old app |
Open the exported file through an appropriate contact or spreadsheet tool, if possible, and compare it with your control records. If reminder schedules or app-only notes are absent, add them to the worksheet while the old app is still available.
Screenshots can help with a few settings, but they are not a searchable or importable backup. Store them securely if they contain personal information.
Test the new app with a small sample
Move five to ten control records before attempting the whole list. Include:
- A birthday coming soon.
- A date near the end of the year.
- A person with no saved birth year.
- A person with a note.
- A customized reminder.
- Two people with similar names, if your list has them.
Compare every available field. Check whether the destination changes date formats, assumes a year, drops notes, or creates duplicates when a contact already exists.
Also learn how the new app handles updates. Some apps copy contact data during import rather than maintaining a live link. Editing Contacts later may not update the imported app record.
A failed sample is useful because it exposes the mapping problem before hundreds of records are involved.
Move the full list without creating duplicates
Once the sample is correct, use one migration route for each source:
- Import contact-owned birthdays through the new app’s Contacts workflow.
- Add app-only birthdays through a documented file import, if the destination supports that file.
- Manually add records that have no compatible transfer route.
- Restore missing notes and reminder schedules from the worksheet.
- Compare the resulting total with your baseline.
Do not import the same records from Contacts and a separate app export unless you know how the destination detects duplicates.
If your destination is Birthday Reminder: Tracker, its current App Store listing documents importing birthdays from Contacts. Review and select the people you want instead of copying an entire address book. The guide to importing birthdays without creating clutter provides a selective workflow.
The current App Store listing and privacy policy do not document arbitrary file import or a built-in Birthday Reminder export. Do not assume an export from another app can be opened directly. Use the supported Contacts route or add app-only records manually.
Rebuild reminder schedules deliberately
Names and dates are more portable than notification settings. Expect to recreate at least some reminders.
Start with one preparation alert and one final alert for important birthdays. The birthday reminder timing guide suggests lead times for messages, cards, gifts, bookings, delivery, and travel.
Check notification permission separately from the data import. On iPhone, open Settings > Notifications, select the new app, and confirm notifications are allowed. Then inspect the next few records to make sure their reminder choices are saved.
Use the simple birthday planning system if the switch is also an opportunity to simplify an overcrowded schedule.
Verify the cutover before deleting the old app
Complete two checks.
Data check:
- Compare the total number of records.
- Verify every control record.
- Scan birthdays in the next six weeks.
- Check birth years, notes, and relationships.
- Look for duplicates and missing people.
Behavior check:
- Confirm notification permission.
- Inspect the next scheduled alerts.
- Open any widget after the app data is correct.
- Confirm that editing one record behaves as expected.
A widget is a convenient display, not proof that the entire migration succeeded. Likewise, a successful backup timestamp does not prove that every exported field reached the new app.
Keep the old app installed until these checks pass. For Birthday Reminder specifically, its privacy policy states that deleting the app removes its locally stored data.
Store the backup safely after the switch
CISA’s 3-2-1 guidance is written for organizations, but the principle adapts well to personal records: keep three copies, use two types of storage, and keep one copy separately from the primary device.
A practical temporary arrangement is:
- The unchanged source app.
- A dated export or migration worksheet in an access-controlled folder.
- A current iCloud or computer backup.
Once the new app is proven and the old one is removed, retain the protected export and backup according to your normal backup routine. Name files clearly, for example birthday-switch-2026-09-05, so an older list is not mistaken for the current one.
Frequently asked questions
Does a Contacts export include birthday reminder settings?
No. It can preserve fields stored on contact cards, but it does not include custom reminders, notes, favorites, or gift ideas created only inside another app.
Will an iCloud backup move birthdays into a different app?
No. An iCloud backup restores supported device and app data as part of a device restoration. It is not a file that a different birthday app can import.
What should I do if the old app has no export option?
Leave it installed, make a current device backup, and copy essential fields into a protected worksheet. Test manual entry in the new app before moving the full list.
How can I tell whether the migration is complete?
Compare the new total with your baseline, verify representative control records, scan the next six weeks, and inspect notes and reminder schedules. A matching record count alone is not enough.
When is it safe to delete the old birthday app?
Delete it only after the new list, notification permission, and upcoming reminders have been checked and a protected backup remains available.
A safe app switch is a controlled handover, not a single export button. Preserve the old copy, test a representative sample, and treat app-only details as a separate migration task.
