A Ukrainian couple has developed an app for learning languages: Iterum translates and saves words from articles, books, and videos, and a smart simulator helps you learn them
Returning to intensive English language learning, EdTech marketing expert Ksenia Snitko, together with her developer husband Vlad, decided to create a convenient tool for their own needs — software for learning vocabulary through interesting content. Thanks to Claude, they were able to quickly bring their idea to life and launch the Iterum application, which allows you to read articles and books, watch videos and immediately translate in context, save vocabulary, and then train it.
Iterum is already available on Google Play and the App Store, and also syncs with a Chrome extension. According to Ksenia, it has been installed by 5,000 users in 5 weeks.

As Ksenia shared in Threads, she had a confident B2 level, but she wanted to read more complex articles and books without the risk of forgetting unfamiliar vocabulary.
"We made our own app so that I no longer have to wait to reach C1 in English and think about what to do instead of doomscrolling: I read 2–3 articles on Substack or Medium with pleasure a week, watch video essays and vlogs on YouTube, immediately save vocabulary and, instead of flipping through the feed again, practice the words that the system itself gives me for repetition."
Ksenia also added that the main reason for their entry into the "red ocean" of language applications was the lack of an ideal methodological connection on the market, the overload of existing products with unnecessary functionality, as well as the mismatch between the price and the service provided.
Iterum development lasted about three months, and its beta testing started in early September — and on the third day, the platform received 287 applications. As Ksenia notes, it would not have been possible to get so much targeted attention without Threads. At the end of the same month, the official release took place, and at the end of October, the application rose to 25th position in the Ukrainian App Store. In total, in the first 5 weeks after the release, the number of its downloads reached 5,000 users.

What's inside Iterum?
The Iterum application is built on the principle of “context instead of endless lists.” The main goal is to relieve users of the need to learn words separately from the source.
It supports watching videos on YouTube (with synchronized subtitles), reading articles via links, and working with books in EPUB and PDF formats (both within the application and via a special extension for the Google Chrome browser).
While reading or viewing, you can click on an unfamiliar word or an entire phrase — the system will translate them based on a specific sentence, determining the level according to the CEFR and frequency of use.
Instead of the classic rating of "how well do you know the word", the intelligent system itself analyzes the correctness and speed of answers, forming an individual repetition schedule. AI exercises are also available, created based on the words saved by the user.
The application currently supports learning English, Spanish, French, Polish, and recently added German and Italian.
Iterum operates on a Freemium model: basic simulators, saving materials, and creating your own collections are available for free, while advanced personalization features and advanced artificial intelligence are included in the paid Iterum Advanced subscription. The application is available for iOS (App Store) and Android (Google Play) users.
