Use Call-to-Action ads to draw consumers towards exclusive (free) information in exchange for an email address. For example, creating an EBook called “The future of B2B Lead Generation” will get attention and adding CTA such as “Get it free only for today!” pushes the person to download the book and creates an opportunity to get their contact details.

Our favorite messaging service takes security seriously—it's Snowden-approved!—using its own open-source protocol to do end-to-end encryption, even on voice calls. It's not as much fun as some of the others, but still supports sending photos and video, plus group messaging. On Android, Signal can completely replace the SMS texting app; on iPhone you need to get other users to download Signal or you can't talk to them.

What if there were a worldwide group of talented ethical programmers voluntarily committed to the idea of writing and sharing software with each other and with anyone else who agreed to share alike? What if anyone could be a part of and benefit from this community even without being a computer expert or knowing anything about programming? We wouldn’t have to worry about getting caught copying a useful program for our friends—because we wouldn’t be doing anything wrong.

The first formal definition of free software was published by FSF in February 1986.[21] That definition, written by Richard Stallman, is still maintained today and states that software is free software if people who receive a copy of the software have the following four freedoms.[22][23] The numbering begins with zero, not only as a spoof on the common usage of zero-based numbering in programming languages, but also because "Freedom 0" was not initially included in the list, but later added first in the list as it was considered very important.

Software can be expensive if you're not smart about it. Free programs have been a mainstay of the desktop experience for decades, and the offerings only get more powerful and fascinating each year. As PCs compete with smartphones, it gets even better. Software developers can adopt an ad-based model, donation-ware to keep things afloat, or a shareware/freemium model that charges for extra features.

The obvious choice of Office tools if you are a firm believer in open source, LibreOffice was a fork from the original OpenOffice years ago (itself an offshoot of StarOffice). Inside are word processor, spreadsheet, and presentations programs, a vector graphics editor, a math formula editor, and a database. It's a little more awkward to use than the desktop version of Microsoft Office, but you can't beat the price. Grab the LibreOffice Viewer app for Android to look at files.
