I spend a lot of time searching for, testing and eventually recommending apps for a variety of mobile platforms. Android, iOS, BlackBerry, Windows Phone, you name a platform and I've published lists of my favorite applications for it. Frankly, it's difficult nowadays to find new and interesting mobile apps I haven't spotlighted in the past. So I reached out to my 1,750 or so Twitter followers, most of whom are avid mobile-app users, for their recommendations.\u00a0Here are the top 15 they suggested.\u00a0I mostly included apps that I haven't covered in the past, in hopes that you'll find a gem or two that's new to you. Pocket for Android Pocket for Android, formerly called Read It Later, is a digital-bookmarking app that lets you "pocket" articles, pages and videos you find on the Web so you can read or access them later. Pocket is available on your PC or tablet, too, so you can pocket an article using your Android smartphone and then access it later on your computer or tablet.
