Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Lower prices: the monthly subscription now costs less, and a new 3-month plan saves even more per month.
• Free daily limits are a little tighter. If they're not enough, subscribe to Plus to keep going.
• Swipe translation now uses AI Natural Translation by default. The cloud, on-device and AI Natural engines share one daily limit, and you can switch anytime in Settings.
• Pronunciation now uses AI voices only: Cloud AI for words and Local AI Voice for sentences by default. Both share a daily limit, and replaying the same content on the same day counts once.
• The getting-started guide has been updated, and you can now practice in the source language you choose. Try it again anytime from Help › Quick Start.
• Swipe translation and double-tap lookup now also work on linked news headlines, such as those on the BBC home page, plus other fixes and improvements.
