When we choose apps to include in our roundups, we're after those that primarily excel in two areas: function and design. A functional app is either unique in its capabilities or simply works better than others. Apps with great designs are a joy to use. Android 9.0 Pie introduced a good range of app-specific improvements, so we also prioritize those apps that use new system features and reflect the latest visual styles. Droid Apps

Calibre is the giant of ebook management, and this app is the perfect (ahem) companion for it. With just a few clicks, you can add any book from your computer to your eReader over USB or Wi-Fi. You can also store your ebooks on the cloud for easy access from wherever you are. What's so surprising is how well it works, and how easy it is to use. If you've got a lot of ebooks and are ready to cast off the shackles of Amazon, this is the app for you.


Over the years, some titles have been dropped from this list, as they are overshadowed by new contenders or fall behind in updates or features. Newer, better apps have taken their place. Yet, some apps still hang on to the top spot tenaciously. To create a little more space for new blood, we asked our editorial staff which new apps changed their lives in 2019. Here's what stood out: Droid App
At its core, Any.do is a list manager. You can quickly create a shopping list and have it synced among your devices and even share the list with others. The app also doubles as a task manager, keeping you on top of what needs to be done. This very capable app sports many features, but we particularly like one called the Any.do Moment, which encourages you to take a second and review your plans for the day. Lists are one thing, but building good productivity habits is quite another.
You now know how to download Google Play Store to ensure you have the latest version. This method will work on almost any Android device, but there may be slight variances depending on your Android version and OEM. Do keep in mind that this will not work on Amazon Kindle Fire devices. That’s an entirely different process which may also require you to root your device. Droid App
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. Android App

Everyone needs to file their taxes every year. Most people will probably have an easier time using dedicated tax software (and some might still enjoy preparing them by hand), but more ambitions filers or those with simple tax returns can get away with using a mobile app. Intuit's TurboTax Tax Return App is the best one we reviewed this year. Among its top features are an excellent user interface, support for all major tax forms, and innovative help options. If you get stuck at any point, you can just open up the Virtual Assistant, which keeps a running dialogue of the help topics you searched for, or use SmartLook to connect to a tax expert via video chat.

The big risk is malware. In our Android app security basics article, we recommended sticking to Google Play and avoiding third-party app stores. The security policy on different Android app stores will vary; some will perform similar safety checks to Google, while others won’t. If you are going to take the risk, then consider installing one of the top Android security apps first. New Droid Apps

Nine is a very reliable email client designed to work with all of your accounts. The clean interface and the optional conversation view make reading and replying to email intuitive. One of the coolest features is the ability to customize the notification actions, including an incredibly useful "Mark as read" option. It isn't cheap, but it's only a one-time $14.99 charge for a much-improved email experience that also integrates calendar, contacts, notes, and tasks functionality. New Droid Apps

It seems like just yesterday that Instagram was adding video. Then direct messaging. Then advanced photo editing put it on par with Photoshop Express for image correction and manipulation. Instagram Stories is now far more popular than Snapchat's similar feature. And anti-bullying features should make it more palatable for some. With a clean, minimalist interface, Instagram is the current king of social photo apps.

Firefox is lickety-split fast and has a clean design that is a joy to use. Mozilla makes a big point about how it doesn't collect your data, and we are pleased to see that the app comes with a full complement of security settings—including an option to protect your information from advertisers and a private browsing mode. Like the desktop version, Firefox for mobile has a robust selection of plug-ins, excellent tab management, and a dynamic start page for bookmarks and the latest headlines. You can even sync settings, history, and tabs with the desktop variant Android App
GetJar’s clever draw is to offer premium apps to users for free to generate traffic, and then monetize that traffic with advertising dollars. App developers considering GetJar might be tempted by the virtual currency tie-ins, and the option to target new users with different kinds of promotions. Be warned, though, the submission process might take a while.
Feedly takes the RSS feed into the modern age, and it's the easiest way to stay on top of all your favorites sources of news. You can view everything all at once if you want, but Feedly also lets you categorize your sources for focused reading or use its Today tab, which shows you the top stories from each category. Additionally, you can make Feedly look as simple as you wish, with minimalist text-only layouts. It's a great way to keep informed with the days' headlines and it offers useful integrations with other services as well. Droid App
