Video Delay Cam: Replay Mirror

Video delay camera with instant replay for practice: Replay Mirror shows what the camera saw a few seconds ago. Do your swing, jump or routine, then look at the screen and watch it play back — nobody has to hold the phone and nothing has to be pressed. ▶ HOW IT WORKS • Set the delay anywhere from 0.5 to 30 seconds in half-second steps, with the slider or the + and − buttons. • See the live and the delayed view side by side, or the delayed view on its own, larger. • A countdown ring on the delayed view shows when the next delay window starts. Turn on the tick sound to hear it without looking. • The screen stays on while the camera runs. • Back or front camera. Mirror the picture if that is easier to follow — saved clips are never mirrored. ▶ PAUSE AND REPLAY • Pause to hold the stretch the delayed view just showed: as long as your delay, up to 10 seconds. • Scrub through it, step one frame at a time, or play it again at 0.25×, 0.5× or 1×, on a loop if you like. • The camera keeps running while you review. Tap Back to live and the delayed view carries on. ▶ DRAW ON THE FRAME • Add lines, angles and circles over the paused frame and drag their handles into place. • Lines show their tilt from horizontal, angles show their degrees. Up to 8 shapes at a time. • Handy for checking a knee bend, a club shaft, a back angle or a take-off. ▶ SAVE AND SHARE CLIPS • Save the last few seconds or the whole paused stretch as an MP4 video clip. • If you allow it, clips are added to your photo gallery. The app only adds — it never reads or changes your other photos and videos. • Every clip is listed in the app with a thumbnail, its length, picture size and frame rate. Share it or delete it from there; a copy already in your gallery stays. • Up to 300 clips. The clip list is backed up once a day (the newest 3 are kept) and can be restored. ▶ FOR ANY PRACTICE • Golf, tennis or baseball swings, gymnastics, dance, martial arts, lifting form, jumps and throws. • Stand the phone on a tripod or lean it against something, step back and train. • The frame rate the camera really delivers is measured and shown, together with the picture size and the memory the delay uses. ▶ GOOD TO KNOW • Video only: the microphone is never used, so the delayed view and saved clips have no sound. • The picture size is picked automatically to fit your phone's memory. Short delays can run at 720p; longer delays drop to 480p or 360p. If a delay does not fit in the memory available, the app tells you the longest one that does. • Angles are measured on the flat screen image; camera perspective is not corrected. • The camera runs only while the Coach tab is open. Frames are kept in memory only temporarily, for the delay and for replay, and then discarded; nothing is recorded unless you save a clip. • There is no video player inside the app — watch saved clips in your gallery or share them. • Portrait only. • No account, no sign-in. Settings and the clip list are saved on this device. • Ads appear on the Clips screen and sometimes after you save a clip — never while the camera is running.

Fixed a crash on some phones: while the delayed camera ran on the "Coach" tab, it could store more video frames than the memory the app is allowed to use, and the app closed shortly after it started. The delay buffer now stays within that limit. If the delay you set does not fit, the screen tells you and, when a shorter delay fits, offers "Use … s".
