Translate overlay for ios apps that are in foreign languages? Chinese/Japanese etc.

  on android i saw apps that can translate the screen live — is there anything like that on iphone for iOS app translation?

 when i was in china trying to use alibaba or local chinese maps, i had to screenshot + translate nonstop, which got old fast.

 apple’s screenshot translate button helps, but it still feels like 5 clicks every few seconds.

 is there a real‑time screen translator / live OCR / on‑screen text translation (maybe picture‑in‑picture overlay or subtitles) so i can use foreign apps without the constant screenshot flow? any advice?
