Four apps, one rule.

Neural noise removal for voice memos, interviews, lectures and video. The model runs on your device, so the recording is never uploaded and the whole thing still works with the network off.

Full IELTS practice across listening, reading, writing and speaking, with instant feedback on the two sections that normally need a human to mark them.

Check an unfamiliar room for hidden cameras using your phone's own sensors — a network scan, an infrared check, and a lens reflection sweep.

Text and camera translation with downloadable language packs, so it keeps working when you are abroad with no data.
