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 Droid Apps
The very specific focus of F-Droid is to offer free and open source software (FOSS) Android apps. It’s basic, but apps on the store are categorized, and the list is searchable. You’ll find a big selection of free apps here, all of which promise no tracking, no ads, and no dependencies. It’s worth checking out for free apps, especially if you support the open source movement. Droid Apps
Sometimes the most secure message is one that simply doesn't exist. That's the thinking behind Wickr Me, a fully encrypted secure messaging service that even handles media messages. The twist is that you set a lifespan for each message, ensuring that your private messages stay private, the way Snapchat message do. And, if you doubt their security chops, here's what the company's founder told the FBI when they asked for a backdoor. Droid Apps
The library is an often-overlooked public resource (and some are modernizing quickly), but OverDrive brings it back into the fold with the newly redesigned, Libby. Supported by over 30,000 libraries worldwide, the app lets you access your local library's array of available ebooks and audiobooks. Use it to download titles, place holds on titles not yet available, and consume your borrowed content. The only requirement is a library card (or its digital equivalent).
There are a lot of apps out there that pay lip service to security and privacy, but Signal was built from the ground up with the goal of letting people easily communicate without having to worry about being overheard. The Signal app is a complete phone and SMS client replacement (though it works just fine as a standalone app, too) for sending and receiving encrypted calls and messages. A recent update has greatly improved the app's look and feel, proving that security and usability don't have to be at odds. Droid App
Don't get us wrong, some of us love Instagram. But if you want more control than Instagram affords, try Google-owned Snapseed. This app straddles the line between full-fledged image editor and filter app, all in a sleek and attractive package. Best of all is the amount of control it gives you over how filters and effects are applied to your images. It even lets you make non-destructible edits to raw camera files and make adjustments to exposure and detail levels. Droid App
