Is there any wallet app that can be used as cold storage for Ethereum the same way Electrum can be used for Bitcoin?

Basically the title. I want to get a Ethereum wallet, but I still don't want to buy a Trezor, and I don't trust hot wallets. With Electrum, I can put my actual wallet in an offline device, get its public key, and create a watch-only wallet.

I can use the read-only wallet to

• create receiving addresses
• create unsigned transactions
• broadcast signed transactions
• see my balance and transaction history

And the cold wallet to

• sign unsigned transactions

Is there any app that works like that, but for Ethereum?
