TextTutor is the missing piece for your Russian language learning experience. While most language apps have you speak, drag, or match words, TextTutor makes sure you are fluent, not just at speaking but typing as well. Never miss the conversation. TextTutor gets you typing the most essential words fast, so you can keep up in the group chat. Feel confident in your typing abilities. You will learn where every letter is on the keyboard, and learn the slang that local speakers use to speak more quickly and fluently. App currently supports the Russian language, but others are coming soon. Have an idea for a feature? reach out! We want to make an app that you want to use.

Verdict
The clearest difference is device support: LangKai at 3 against TextTutor's 1. LangKai also leads on iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.
