Spent some time sending and requesting coins,
Many successful transactions, made mistake while typing an address and the app notified me about an invalid address.
Creating request QR works good , scanning it sends exact amount of coins to the address as requested.

Had crushes ,  first crush crushed but coins was sent, after more successful trunsactions i tried to replicate the transaction before the crush but failed  to crush it .
Another crush did not send coins and after restarting app kept crushing when sending the same amount of coins , changing the amount fixed the problem. This crush looked rundome so i coldent try to replicate the crush.

Another problem , i coldent make tow transactions in a row, right after making transaction and the wallet did not synchronized yet, when sending second time app sayes all funds in wallet are waiting for apruval .

In conclusion , very user friendly app, only couple crushes from tens if not few hundreds trunsactions.

Tested on HTC One android.V.4.1 And iconia Tablet android.V.4.0.3

Crushes ocured on HTC (but i used it more).
