It was great until the app started using all my battery power even when i wasn't using my phone. It took 30 or 40 percent over 7 hours when i was asleep. Then after uninstalling the app, some data still lingered from the app that continued to zap my battery power. To rescue my battery i had to reinstall, clear data and then uninstall it again. Never had so much trouble with any app using that much resources, especially when idle. The app usefulness is trumped by problematic programming.
