IMHO your real problem is that Readlang do es not offer enough features that would differentiate it from other free offerings.
- Store all your translations, along with their contexts, to your account?
and have a accompanying web-apps which let you:
- review those translations with flashcards, prioritizing the most frequent words in the language, and utilizing a spaced repetition algorithm so that you spend more time on the words and phrases you find difficult?
- export of those flashcards for use in other apps such as Anki
- upload novels to read in a distraction free, paginated reading interface which works well on mobile devices?
- watch videos with sync'd transcriptions?
- share and vote on native texts and videos with a community of language learners?
If so, please let me know!
And if you didn't realize any of the above - I take the blame for not communicating it better on the landing page. The problem is that overwhelming users with info usually isn't a great idea either. Hard to strike the right balance.
I don't expect everyone who installs the Google Translate extension to install Readlang - since mine is targeted mainly at intermediate and advanced language learners.
