Six 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.

Write what you actually want to say to someone, pick how it should sound, and get a short song of it about a minute later. Or paste lyrics you already wrote and have them sung exactly as they are.

Blurish finds the faces in a video or photo and covers them for you — with a blur, a mosaic, a solid colour, an emoji or a sticker — and follows each person as they move. All of it runs on your iPhone; nothing is uploaded.
