A new update for the Lernabit Android app should be appearing soon in your list of updates.
Version 2.4.16 includes a major change to the home screen by moving the search box up to the top of the screen. Where the search box used to be, you will now see a list of suggested notes that you might like. These suggestions are based on the notes in your review list, which is a good indication of the types of content you want to learn more about. If you don't have any notes on your review list yet, it just pulls up a random selection of notes with a high score (more on that in a second). As you add more notes to your review list, it can give better suggestions.
The suggestions are also partially based on a scoring system that has been built to help find the best notes on Lernabit. The score for a note is based on a variety of data points like word count, the number of people who have that note on their review list, and others. However, the score does not consider the publication date of the note. There is already a feed to see the most recent notes in chronological order. The scoring algorithm is designed to help find the best notes overall and to dig up notes you might find interesting regardless of when they were created. It is only used sporadically right now and will be applied to more features in the future as the algorithm is tweaked and improved.
Also new in version 2.4.16 is a major performance improvement in infinite scrolling, plus some other minor bug fixes, design changes, and performance improvements.
