CleverMining Widget (Ad Free) for Android
You can view the hashrate graph by simply tapping on the widget. The Paid version removes ads and provides the ability to set refresh intervals as short as 5 minutes.
You can see your current hashrate, confirmed and sent balances and even automatically convert the balances to one of the supported currencies. Just type in your BTC address, choose the currency, refresh interval, whether you would like to receive notification for low hashrate and you're ready to go.
The widget has two sizes: a 2x1 and a 1x1 widget that shows the hash rate only
