LACA is a live voice translator and visual companion. This page covers the questions people ask most often, and how to reach a person when something still does not work.

Getting started

Live conversation — open Translate, choose your language pair, tap the microphone, and speak. LACA translates and speaks back.
See and ask — open Discover, allow the camera, point at something, and ask a question out loud.
Languages — English, Vietnamese, Dutch, Russian, Chinese, Japanese, Korean, French, Thai, Spanish, German, Azerbaijani. Change the pair on Translate, or the interface language in Settings.

Permissions

Microphone — required for live translation and asking questions. If the mic stays silent, check iOS Settings → LACA → Microphone.
Camera — only for Discover. If you see “Allow the camera,” open iOS Settings → LACA → Camera.
LACA does not need Contacts, Photos, or Location to work.

Premium and restore

Optional non-renewing plans remove daily limits for a fixed period. They are sold through the App Store.

Open Settings in LACA (or Premium from the welcome screen) → choose a plan → continue with Apple ID.
Already paid on this or another device with the same Apple ID? Tap Restore Purchases on the Premium sheet.
