Learn languages while you type. Turn everyday typing into effortless language learning. As you type, the keyboard shows a natural translation of your sentence along with phrase-by-phrase meanings, helping you discover how the words and expressions you already use are said in another language. Switch between supported languages anytime and learn through real conversations, messages, notes, and searches — without opening a separate translation app. Need to communicate in another language? Simply tap the translation to replace what you've typed with the translated text, ready to send. Key Features Real-Time Sentence Translation See a natural translation while you type, directly above the keyboard. Phrase-by-Phrase Learning Understand how individual words and phrases are expressed in the language you're learning. Switch Learning Languages Anytime Choose the language you want to learn and translate into, including English, Japanese, Korean, and more supported languages. Replace Your Text in One Tap Turn what you've typed into the translated language instantly — useful for messages, email, social apps, and search. Learn From What You Actually Say Instead of studying random textbook sentences, learn from the things you naturally type every day. No Copying and Pasting Translation happens directly inside the keyboard, so there's no need to constantly switch between apps. You already type every day. Why not learn a language at the same time? Type. Translate. Learn. Terms of Service: https://langboard.aiyuchat.com/terms.html Privacy Policy:https://langboard.aiyuchat.com/privacy.html

Verdict
The clearest difference is in-app purchases: TranslateFlow at none against Langboard's 3. TranslateFlow also leads on ads (none vs shown) and iOS requirement (16.0 vs 18.0). Langboard's advantage is update cadence (every 2 days vs weekly). On price and device support there is nothing between them.
