Just wish I was able to switch the clock to a 12 hour mode.. I work in a Ford Garage and I leave my iPod plugged in and listen to music/podcast through Bluetooth headphones.. It's nice to just give a quick glance and have the clock so boldly displayed, but it's 24.. Not a huge deal, just a feature I feel would greatly improve the app.. ### 5/5 — Nice! *2012-01-16* Nice app. Does what it is supposed to do. Doesn't crash and us easy to read the graphs. Definitely recommend this app. ### 5/5 — Useful app *2012-01-14* It is a helpful app to have. ## Frequently asked questions about BatteryNow ### What is BatteryNow?
