Change language
Tap the globe on Today or inside a lesson. Select English, 한국어, 日本語 or Use device language. English examples and your progress stay the same.
Speech is unavailable
On-device English recognition depends on device and language resources. Check microphone and speech recognition permissions in iOS Settings. You can always type an answer or choose I practiced aloud · compare with example.
Continue and review
The course has 80 days. Days 1–3 are open initially; finishing all three unlocks Day 4. Each later day unlocks when all earlier days are complete. No calendar wait is required. Choose an open day in Today or Journey. Review available expressions separately and collect achievement badges and XP.
An answer is outside the checks
The app checks prepared answers and representative errors. An unlisted answer is not marked incorrect. Use the hint and example to check it yourself.
Contact support
Include the app version, iPhone model, iOS version and a description of the problem. Send only information you choose to share; recordings are not required.
Optional Unity banner ads
Starting with version 1.1.0, ads are off until you confirm that you are 16 or older and allow banners. Refusing ads does not restrict lessons. Banners appear only on Today, not during lessons or reviews. Unity LevelPlay and Unity Ads may process device identifiers (including vendor or SDK-generated identifiers), IP address and country-level location, ad views/clicks and other usage information, device/connection information, and SDK performance/diagnostic data for advertising, analytics and service operation. We do not send learning records, typed answers or microphone audio to Unity. The SDK is initialized only after permission. We pass no consent for personalized advertising and an opt-out of data sale/sharing; we do not request access to IDFA or cross-app tracking. You can disable banners in the app settings at any time. This destroys displayed banners and stops new ad requests; on the next launch the SDK is not initialized. Previously received data is subject to Unity's retention and deletion policy. Contact Unity through its privacy policy to exercise rights over its data. The app does not set a custom user ID or supply purchase history; it has no purchases. Your ad choice is stored locally. Users under 16 should continue without ads.
