There is no official Electrum app in Apple App store to begin with, so any similar app you find there is run by scammers and that is why you have lost your funds, sorry about that. You should have asked here first if you were unsure of what you're doing, it would have saved you your funds.
When I launched the app, it asked for my seed phrase. I already had a wallet on Android and merely wanted to access my account. I entered the seed phrase, but nothing happened.
Why did you want to have your wallet in two devices, two online devices for that matter. Doing that only exposes you to more attack vectors. I don't know how much you lost here, but the best action is to take it as a hard lesson and learn more about wallets and opsec in this forum.
