FORGET 15 MINUTES A DAY. You text all day. Keyla turns it into language practice. Type in your own language, in the apps you already use, and see it in English (or another language) right above your keyboard. HOW IT WORKS • Live translation bar: see your message translated while you type. • Tap the bar to replace your text with the translation. • Double-tap a word in the bar to see what it means. It's saved to your list. • Your words, your sentences: saved words keep the sentence they came from, your own message. • Swipe through "Words I don't know": right for "I know it", left for "I don't know". • Quick quizzes in your notifications: press and hold, pick one of three. No need to open the app. • Can't read a message? Copy it and translate it right from the keyboard (Keyla Pro). MORE • Offline translation: download a language pack and translate without internet. • Make Keyla your default translation app. • Lock Screen and Home Screen widgets with your words. • Autocorrect and familiar layouts like AZERTY, QWERTZ, QWERTY with Ñ, and Telex. LANGUAGES Write in English, Spanish, French, German, Portuguese, Vietnamese or Turkish. Learn English, Spanish, French, German, Italian, Portuguese, Dutch, Vietnamese, Turkish and more. Some languages need a device with Apple Intelligence. PRIVACY Keyla needs Full Access to translate as you type. Your messages are saved only on your device. When a translation goes through our server, we don't store or log your text. For passwords, iOS switches to the system keyboard, so Keyla doesn't see them. KEYLA PRO Keyla is free to download and includes a free amount of live translation. Keyla Pro is an auto-renewable subscription that keeps live translation going and adds clipboard translation. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is canceled at least 24 hours before the end of the current period. You can manage or cancel it anytime in your App Store account settings.

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