Hi there guys! I was looking for a widget Android application to monitor my addresses balances. I did find only one like this, but I didn't like it. So I decided to make my own.
Feel free to use it or request addons if you want.

Description:
A simple but useful widget that will show you the balance of configurable Bitcoin addresses.
It will update every 10 minutes only, fast enough for the Bitcoin network and very low power consumption app.
Under the balance you will find how much time elapsed from the last update (just now, 5 minutes, 1 hour, etc)
More than one instance supported.
In case of no connection, the last know value will be retained in memory (never a 0.0 balance will be shown, something that I didn't like from other apps)
You don't need to provide private keys, 100% secure, no chance that you will lose your coins! Never put your private key on untrusted places!
No ads, no strange permissions, no shit.

TODO:
QR Scanner
Other Cryptocurrencies?
More random servers to get balance information (blockchain.info only atm).

Atm it only displays the balance in Bitcoins. A local currency information box can be added in next versions. Smiley

I was thinking in doing this in a more "decentralized" way, I mean, atm I only get the balances from blockchain.info website. It works really well, but adding more sources (blockcypher, coinbase, bitref, etc) and select randomly from the online ones will turn this app in something unbreakeable isn'it? (the unique way of being offline will be if it ALL of the sites are offline at the same time)

Add more explorers like Blocktrail and check if balance shown in two explorers, here Blockchain.info and Blocktrail, are same. It will be better. Blockchain.info is sometimes buggy and sometimes server go down.

Useful app, btw! Keep it up!
