Sophos consistently ranks high on watchdogs such as AV-Test. In addition to perfect protection, it offers a varied feature set. The highlight: the app is totally free, even from ads (Sophos makes its money from business customers). Malware protection is based on an online database that also checks the reputation of individual apps and recommends alternatives. New Droid Apps
Airbnb should be your go-to app for finding rooms, apartments, homes, and other unique accommodations when traveling, if you don't want to go with a traditional hotel. The length of your stay need not be short-term either; some locations let you book a stay for several months, which may appeal to people working temporary jobs in new places. This travel app also highlights other experiences and restaurants, so you can find out about everything a locale offers.
Your bag of holding for internet content, Pocket saves articles, images, and videos for later reading. We especially like how it reformats articles for more comfortable reading on a mobile device, and how it syncs content to your tablet, phone, and online account.

Weather Underground combines a slick design with a focus on really useful weather information. We particularly like the ability to report weather conditions in your area and the extremely useful comparative forecasts that deftly show how conditions have changed since yesterday. With an accompanying set of useful widgets, it's the best weather app on Android.
This calorie counter and exercise tracker aims to help you lose weight the old-fashioned way—expending more calories than you take in. With its smart design and an extensive library of foods, it makes quickly logging the calories you take in and what you burn while exercising a snap. A barcode scanner makes it even easier to log that post-workout snack. This fitness app also plays nice with other such apps, so your data won't be tied up in just one place. MyFitnessPal won't give you a whole workout regimen, but it can make you more aware of your habits. PCMag has a full review of MyFitnessPal for the iPhone. Droid App
