Let us know what you think of it. Some people mentioned they would be interested to see widget support for this. If enough people want a widget, we'll consider adding widget support to this app!
v1.1 adds a progress spinner and has some internal changes.
v1.1.1 fixes a crash that occurs when trying to click the same button twice. It also fixes an issue that caused the app not to work on high memory devices.
v1.2 fixes a problem where the app would not work on devices without a sqlite3 binary (which includes most rooted stock ROMs that I didn't account for).
v1.2.1 adds a new icon.
