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.
Every one of them has its own advantages and disadvantages. For a mobile wallet, it is highly recommended if you are the kind of person who likes convenience because with a mobile wallet you can access your funds whenever and wherever you are. On the other hand, we wallets provide are better if you because it has complete features compared to a mobile wallet which is only limited(in some cases). Personally, I'd like to use a mobile wallet over a web wallet.
