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!
