AppShaker is a very simple app which does exactly what it promises. The good thing is, it runs as a background service waiting for any potential shakes on your smartphone. It makes use of the accelerometer, which has become a standard feature of many android smartphones. You can even select and calibrate the sensitivity of the shake through the settings screen. The developer claims that they have designed AppShaker to consume so less battery and memory, such that you will not even notice it running in the background! Apparently, the background service goes to sleep as and when the screen light goes off and when the screen is illuminated again, it wakes up from sleep and becomes active. That’s a neat way to conserve battery, isn’t it? Android devices have pretty bad reputation when it comes to battery life and standby time. So, having yet another background service would mean even worse battery performance. Even Facebook app for android used to have “Shake to refresh” feature, which was eventually removed due to battery issues. I personally wasn’t able to test the optimization claims made by the developer, but was thoroughly impressed with the concept and it’s implementation. I can now open my phone camera app in a flash by just shaking the phone! As a regular iPhone user, I miss this functionality in my iPhone. There is a namesake app on the iTunes appstore which is more about app discovery. The android version though is much cooler and surely deserves a try. Check it out and let us know your opinion.
