When I'm learning a language, I'm like, “Where did you save that listening voice?” Do you ever think “I want to watch the YouTube explanation video I saw before again, but searching is too cumbersome”? If teaching materials are scattered all over the place, it will take time to start learning, and it will be difficult to continue.

HandbookX is the solution to such problems. With this app, you can manage listening audio, YouTube learning videos, and PDF materials all in one place. The learning flow becomes smoother, and repetitive learning becomes easier.

Introduction to how to use

With Handbook X, you can do, for example:

1. Organize listening voice data

Listening is very important for language learning, but if they are stored separately in a smartphone music app or file folder, it's hard to find the sound you want to listen to.

With Handbook X, you can put together sounds for listening, so you can play them right away. The playback speed can also be adjusted (0.5 times to 2 times), so you can listen slowly and understand clearly, and practically train at a faster speed, etc., according to your own level.

2. Organize YouTube videos and learning sites

There are many language learning videos on YouTube, but “where was that video I saw before?” Doesn't it take a while to search for it? With Handbook X, you can save yourself the trouble of searching every time by registering your favorite videos and learning sites. It opens every day, so it's convenient to be able to access it right away without any extra operation!

3. Write notes on PDF materials

With Handbook X, you can write notes directly into PDF materials, making it easier to organize your studies. It's also perfect for taking notes on grammar points, marking answers to problem books, and memorizing them by writing. Being able to write again and again on the same teaching material is unique to digital!

summary

If you use Handbook X, you can centrally manage all the audio, video, and PDFs needed for language learning, making it easier to learn repeatedly. If the materials are scattered, it will take a while before you start learning, but if you use Handbook X, you can quickly find what you need, and you can study smoothly.

If you want to make your language learning more efficient, please give it a try.
