A couple says they downloaded a bitcoin wallet app from the Apple store that turned out to be a fake
that scammed them out of their bitcoin. There are so many apps on the Apple store, it is impossible
for them to fully evaluate every single app in their store. Don't assume just because it is from Apple that it is safe.

Sparrow is a legit bitcoin wallet, but it is a desktop-only wallet. There is no phone version.
So if you find one in the Apple or Play store you know it is a scam.

Anyone with large amounts of bitcoin should be using the passphrase feature IMO,
so they can't steal your bitcoin with just the seedphrase alone. It is your last line of defense.
