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.
My smartphone memory capacity is very wide to accommodate the mobile wallet application...
I really like the Atomic wallet concept because you can have a 'private key' for each coin listed there. mobile wallets and web wallets have different levels of effectiveness, you can transfer your coins from anywhere while web wallets are not, so I prefer mobile wallets like Atomic.
