Hedera provides a very accessible way for users to connect with and perform transactions on their favorite apps. This comes in the form of Composer, which is a browser extension of Hashing Systems. Composer provides users with a non-custodial crypto wallet from which users can easily manage their HBAR, making transactions, interacting with smart contracts, and buy Hashing Name Service domains, etc.

Note that it is currently available on only Google Chrome.
