After downloading and using eight different vocabulary programs, we think Vocab1 is the best one because of the sheer number of words it tests you on. Its library houses 142,647 words and more than 600 word lists, making it the most comprehensive vocabulary learning software. Vocab1 emphasizes learning words in context and lets you choose from a variety of activities, which makes it easy to find ones that suit your learning style. This variety and the huge word database make it a good choice for improving your vocabulary.

Vocab1 has a huge library of words and uses context to help you learn them. Because it has such a large library, over 142,647 words, it’s easily the best stand-alone vocab software available.
Each word’s definition contains information about its etymology and pronunciation as well as other standard dictionary-entry fare. While the huge number of entries can be intimidating, one of the features that make Vocab1 the best vocabulary software is its word lists, which keep your learning organized. You can create lists of specific words you want to work on or use one of the program’s ready-made lists, like those for college entrance exams. Vocab1 encourages you to interact with the words you learn through activities and quizzes, including sentence completion activities, flashcards, spelling tests and crossword puzzles. Vocab1 also sets itself apart from the competition by emphasizing learning words through context. The program is structured in such a way that you encounter vocab words in sentences, which helps you retain them better over time. You can also track your mastery using the program’s analytics, which show your improvement over time. The program comes with a money back guarantee, and you can return it within the first year if you aren’t completely satisfied. You can also contact the company via email or phone if you run into problems with the program.

WordPal is a bare-bones vocab program that may be a good choice if you want something simple. The software uses multiple-choice quizzes to help you build your vocabulary.
While we generally like programs that have a variety of learning activities, WordPal is a low-cost option that can help you bulk up your vocabulary for college entrance exams. Despite its basic design, the program has at more than 4,000 words to get you started. It includes lists organized into 27 categories so you can focus on vocab specific to things like architecture or mathematics. You can also select vocabulary based on tests you’re prepping for, including the GRE and SAT. The software measures your success based on the results of the multiple-choice quizzes you take. If you want to try out the program before you purchase it, you can download the free trial. When we tested WordPal, we found there aren’t a lot of settings to adjust, and there were times we wanted to change the font size so words were more readable. The support features are also limited; you can contact the software creator through email or refer to the FAQs page.
  • Six different quiz and flashcard activities
  • One-year money back guarantee
  • Inexpensive compared to other programs
  • Hasn’t been updated since 2014
  • Only contains about 4,000 words
  • Limits number of downloads

Overnight Vocabulary

If you don’t have a ton of free time but still want to improve your vocabulary, consider Overnight Vocabulary. While this program has a tiny library compared to our best pick – only 300 words total – it’s a solid option that uses audio clips of dictionary entries to help you learn new words.
The manufacturer’s site is a bit confusing, and it doesn’t sell CDs, just audio files. The program comes with seven hours of lessons, which you can load on your mobile device and listen to on the go rather than being tied to a computer. Overnight Vocabulary’s thirty lessons last 15 minutes each, which is shorter than the sessions in other programs. Also, because you listen to the lessons, there aren’t any interactive games and quizzes like in other vocabulary software. However, the program comes with a 150-page PDF you can use to follow along with the lessons. The program is made to improve your vocabulary with a very refined list of essential words. You can’t create your own word lists, and Overnight Vocabulary doesn’t have word lists to help you prep for college entrance exams like other software we reviewed. Still, if you’re an auditory learner or don’t have much time to sit at a computer, it might be worth a try.
  • Seven hours of audio lessons
  • Lessons are only 10 to 15 minutes each
  • 150-page PDF of the lessons so you can follow along
  • Need to buy a separate version for college entrance exam prep
  • Only teaches 300 words
  • Doesn’t have interactive tools

Why Trust Us? 

As writers, we’re always looking for new ways to better communicate with our readers, so we know a thing or two about the importance of a good vocabulary. However, we didn’t just use these vocabulary programs to beef up our next review; we worked in each one to find out which features are the most useful. We have the resources to test and compare these applications side by side and spent hours poring over each one to become familiar with how the software works. Because of our testing, we can fairly evaluate each program’s offerings.

How We Tested 

We searched online for the best vocabulary software and looked at each program’s platform compatibility, specifically checking if it works with Windows, Chrome and Firefox.  We also read forums and online articles to see what actual users had to say about their experiences using each software, and we considered price and the quality of the program’s features to see if the application was worth the investment. Before we started our hands-on testing, we viewed all the available tutorials so we knew how to use each program to its fullest extent as well as to identify any unique features.

As we completed each software’s activities, we kept an eye out for bugs and lag that could eat up too much of your time. We also tested our own vocabulary knowledge to see how well the programs track progress and to find out if the data was helpful and accurately reflected our experience. In addition, we paid attention to how difficult the words in each program’s library are to see which software is best for English language learners versus people preparing for college entrance exams.

We also compared the programs’ interfaces to find user-friendly software. Finally, we checked out each software provider’s support features and preferred those that have a variety of contact methods, including email, live chat and phone options.

Key Features to Look for in Vocabulary Software 

Number of Words
It’s important to look for software that has thousands of words so you can keep coming back without running out of new vocabulary to learn, but the best programs also organize their lessons well. We found that applications that breaks up words into categories, such as test prep and common words, are most useful because they let you improve your vocab in specific areas.

Games & Quizzes
Familiarizing yourself with new words takes a lot of practice, so look for vocabulary programs that have a variety of activities that expose you to the words in different ways. We looked for programs that focus on using words in context because it’s the fastest way to learn new vocab. However, we also found that software with activities that mimic tests like the GRE and SAT are well suited for students studying for college entrance exams.

On-the-Go Learning
While you can download most of the software we reviewed directly to your computer, you might want to consider the number of devices you can download the software on when you purchase a single license. When you buy a program you can download on multiple computers – such as a home computer and a laptop – you can access lessons in different locations or share the software with family members.

We’d like to see more products sync between devices, which makes it easier to track your progress when you use more than one computer. You might also want to consider an application that comes with a mobile or audio version so you can learn on the go.
