I bought an iOS app that allows you to remove metadata (EXIF data) from a photo.
The app is called ViewExif.
It allows to remove metadata from the app, which does not remove the original photo but creates a new photo that has no metadata.
Also, it adds the view exif function on your default photo app.
You tap on the ViewExif menu from the photo app and also save without metadata, without going into the ViewExif app.
It’s a really easy to use app.
