Androcats and LoudWords My vocabulary trainer app


LoudWords My vocabulary trainer app is the first published app of Androcats.

Androcats as its first project aspired to make an educational, useful app for Android users.

The idea of LoudWords came from a personal need, which turns into a practical and helpful app for language learners.

The developer wishes all LoudWords' users to enjoy their studies and success in learning languages.

LoudWords is free to download, but if you find it useful and helpful in developing your vocabulary learning process, please consider supporting the app by leaving a tip or buy a coffee for the developer, she deserves it. :)
