The Dash wallet by Hash Engineering is a Dash-only wallet funded by the Dash treasury. It shows up as "Dash Wallet" in the Play Store.
The wallet has standard send and receive features, including an address book with a copy/paste address feature (but no manual entry), as well as a handy paper wallet sweeping feature. It also has more advanced user features such as a network monitor, connectivity indicator, trusted peer settings, etc.
Most notably, the Hash Engineering wallet has InstantSend functionality, perhaps the only mobile wallet to support this feature at present. This means that the user can carry their funds with them and pay anywhere with instant confirmations....
