Yes. Linguisticat offers an iOS app that can be added as a Safari extension, alongside its web version. It also includes widgets for learning directly from the home screen. On the web, the reviewer notes that it needs no software installation.

Toolio lists Linguisticat as suited to language learners from beginners to advanced, since it supports multiple languages and levels at once. It is not for learners who want structured courses, as it lacks them for in-depth learning and grammar practice. The reviewer also notes minimal feedback, with more focus on recognition than on production skills.

Toolio lists 5 Letter Words, Flexi, AvidX and Pukhto Qamus Extension as alternatives. Flexi generates flashcards with AI for better retention, AvidX helps build a language learning habit, and Pukhto Qamus Extension looks up similar Pashto words and their English meanings. Linguisticat itself holds a Toolio score of 3.9 out of 5.
