One of the key issues hardware and software engineers are dealing with these days is figuring out how to make sure your iPhone is charged when you need it to be. Softorino’s iBetterCharge (Free) is one of the more clever solutions we’ve seen. The simple app lets you know when the batteries in your devices have fallen to a certain level—50%, 20%, 10%, or 5%—so that you can plug it in and juice it up.
iBetterCharge doesn’t require any sort of additional set up. As long as your iPad, iPhone, or iPod touch is set to backup over WiFi, it’ll show up in the menu bar drop-down list, displaying its current charge level. Then, when it reaches whatever percentage you choose, the app will play a sound, an animation, or show a notification. There’s also an option for letting you know when the devices are fully charged. The app makes a lot of sense for iPad users; since the batteries last so long, it’s easy to not notice when the charge is low and it’s time to plug them in.
