We released v0.1.6 of Merit's Mobile Wallet to the Google Play Store in Public Beta!!
You can find it here: https://play.google.com/store/apps/details?id=me.merit.wallet
Please note that we are currently working on synchronization between Mobile Wallets and Desktop Wallets, but it is not yet released. So, for early users like you, you will need to setup a separate wallet on the Mobile App. That means a separate alias, and you'll need an additional invite.
[iOS Users: We are still waiting for Apple to Approve the Merit Mobile Wallet for the iOS App Store.]
