The new photo is placed in your library by its date taken. If you moved the date into the past, it appears on that day rather than at the bottom. Look it up by date in Photos, or open the Recently Added album, where it will be first.

You allowed access to selected photos only. Tap Manage at the top of the library to add more, or go to Settings › iExif › Photos and choose Full Access. Without access, you can still tap the folder icon to import from the Files app.

No. Saving creates a new photo and keeps the original. If you pick “Save & Delete Original”, iOS asks you to confirm, and the original goes to Recently Deleted where it stays for 30 days.

Not by default. When only metadata changes, image data is untouched and quality is identical. The image is re-encoded at 90% quality only if you change the output format (say JPEG to HEIC) or turn on “Match Device Resolution” — and the app tells you beforehand.

Yes. The video is saved alongside the photo, and its date, location and device info are updated to match. One note: the pairing ID lives inside MakerNote, so during a lossless save the app keeps MakerNote even if “Remove MakerNote” is on — otherwise the Live Photo would break.

Focal lengths, apertures and lens model strings come from the EXIF of real photos. For a few devices — mostly brand-new models and some iPad front cameras — no original sample is publicly available yet, so those values are derived from published specs and clearly marked. They are updated once real samples appear.

It changes only what the Photos app displays. No new photo is created and the EXIF inside the file stays the same, so exporting the file later still shows the original values.

Maps in mainland China use the GCJ-02 coordinate system while photos store GPS (WGS-84) coordinates, which differ by a few hundred metres. iExif converts between them automatically.

Up to 100. Tap Select in the library, then swipe sideways across photos to select quickly. In batch editing each field can be turned on individually, and dates can be shifted together.

JPEG, HEIC and PNG. ProRAW (DNG) isn’t supported yet.

While editing, tap More › Save as Template and pick the fields to keep. Then use Apply Template in single or batch editing, or manage templates in the Templates tab.

Open the Settings tab and tap Feature Tour.

iExif does not upload photos to developer servers. Editing is local; iCloud, Maps and sharing you initiate are handled by the relevant system services.
