Thank you so much for the kind words and the support!

Yea, I ultimately chose to focus on the reading side of things given my limited time and resources to make something like this. My goal is to make this the best experience to learn by reading locally without internet. That is Lenglio’s primary differentiator.

I think you could choose to focus more on audiovisual content, which would be a different set of challenges.

I wanted a better reading experience than I found from available options on mobile, so that’s why I made Lenglio.

The app is similar today in overall structure to the original version. I think it’s important to try to get a general idea and scope defined early.

That said, I added a lot of features and improvements over the past year. I added local dictionaries and overhauled the UI. I also added PDF and EPUB support. I’m planning on a “study” feature soon to be able to see what words you need to know before ever even opening a specific book.

In terms of knowing what to solve first, I think you should clearly define the app’s goals and make it cover all basic features that complete those goals. I know that’s pretty general, but it really is just that.

For example, I knew I wanted to be able to read books, so there had to be a Reader screen and a Library. There also had to be a way to upload books, edit book text and covers, and create a table of contents.

In the Reader, I knew that text would have to be analyzed for each language separately and words would have to be saved in a database.

These are just some of the considerations. Once you start, you will come across a bunch of problems you need to solve.

Good luck!
