A web wallet is one such wallet. You do not need to use any additional applications to save it. It is much safer. In my opinion, web wallet is much better than mobile wallet. Using it does not require a separate space. Hopefully the wallet will expand further in the future.
I don't know how you feel using a web wallet, but to me it's totally unsafe cause there are alot of loopholes on the web, it's just like saving your crypto on exchanges and saying it's better for them to be there on the exchange than being in your personal mobile wallet, if the exchange gets hacked, there's a chance you might not get your money back cause it's like keeping your money with someone, when the person gets robbed off that money, how can they repay you ? So storing your crypto on web wallets its a kind of "our hand in your pocket" kind of scenario, try and avoid dramas, it's best you download and make use of a mobile wallet, it's alot more safer than a web wallet.
