About

BSB Mirror

Features
Read full description

BSB Mirror shows your camera image with an adjustable time delay — perfect for reviewing your archery shooting technique right after the shot, without needing a second person or a separate recording device. HOW IT WORKS Position your iPhone or iPad so the camera captures you while shooting. Tap the delay button at the bottom and use a scroll wheel to pick a delay between 0 and 30 seconds. The camera image then shows exactly what happened X seconds ago — like a mirror with a built-in time lag. FEATURES - Adjustable delay from 0 to 30 seconds - Choice of front or back camera - Two-finger pinch-to-zoom with panning, for a closer look - Optional picture-in-picture: always shows the live view, even while the main image is delayed - Supports both portrait and landscape orientation - Automatically adjusts image quality and frame rate based on the chosen delay - Optional on-screen display of resolution, frame rate, and buffer usage for the technically curious PRIVACY BSB Mirror never records or permanently stores anything. The camera image is only ever processed live in your device's memory and is completely gone once you close the app. There are no accounts, no ads, and no data is sent to any server — the app works fully offline. LANGUAGES German and English, automatic or manual selection.
