Coinomi is the biggest (70 blockchains supported + 7 more coming this Friday) and oldest (rocking since 2014) active multi-coin thin wallet in the market for Android and the only one of its kind that provides native dApp support for ETH-based coins, also soon we are releasing our thin Desktops clients for Windows, Linux and Mac. Coinomi's code is open and the wallet app is super efficient as it is a native app in all platforms, so performance-wise there is a huge difference.
