Beware of using this wallet, because the owner is scammer Atomic Wallet and Guarda' owners == SCAM ChangeNOW' owners

Don't really trust any new, unknown and webwallet, I suggest you to use electrum wallet, paper wallet or hardware wallet. Even it's a bit more difficult, but you should think about securing your wallet to prevent from scam or hacked.

Coinomi offers that. They use the same partner as Guarda (Simplex).

Also, sacrificing the safety of your funds for convenience is NOT something I would suggest. These wallets are closed source, so make sure to only use them when storing small amounts.

You can install the following wallet.
Electrum Wallet
Mycelium
Trust Wallet
Coinomi wallet
Coinbase wallet

Edit:
I can see that you posted a almost similar topic on March 08, 2020.

There has been a detailed discussion of the different wallet. I think you should have a good knowledge about the wallet from there.
