BSB Mirror
Read full descriptionHide 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.

See your movement when you are ready to review it. ViDelay turns your iPhone or iPad into a delayed video feedback camera. Set a delay between 0 seconds and 2 minutes, perform your movement, and automatically watch it moments later – without stopping the camera or touching your device after every attempt. Ideal for springboard and platform diving, gymnastics, trampolining, track and field, golf, tennis, volleyball, basketball, soccer, handball, baseball, martial arts, weightlifting, CrossFit, climbing, dance, and many other sports. KEY FEATURES • Live video with an adjustable playback delay • Train continuously without stopping or rewinding • Save videos directly with audio • Select the exact time range you want to save • Frame-by-frame analysis for precise movement review • Filmstrip timeline for quick and accurate navigation • Zoom and freely move around the analysis image • Switch between front and rear cameras • Zoom, mirror, and rotate the video • Automatic orientation and full-screen display • Adjustable video quality and frame rate, depending on your device • Optional grid or crosshair for better visual guidance • Control lock to prevent accidental changes during training REPLAY ON THE BIG SCREEN Send the delayed video to a TV using AirPlay, or connect your device to a monitor or projector via HDMI. Your iPhone or iPad remains the control center while the external display shows only the full-screen replay. SAVE AND ANALYZE Choose exactly which previous time range you want to save or analyze. Saved videos include the corresponding audio and can be stored in your photo library or shared with others. PRIVATE AND LOCAL ViDelay does not require an account. Camera footage and analysis are processed locally on your device and are not uploaded to the cloud.
