"LagMe" is a delay camera that keeps showing your movement a few seconds late—so you can check your own form the instant after you move. No recording or playback controls needed. Who it's for - Golf, baseball, basketball, volleyball, dance and more—anyone who wants to check form right away - Solo self-checks, or coaches showing players their movement - Students and players who want "film from behind, review in hand" without expensive gear Key features - Delay playback: your video plays back on a delay you set. Just move, then glance at the screen. - Save the past: tap save to keep the last N seconds—even movements you didn't think to record. - Wireless two-device link: film with one iPhone placed behind the action, review the delayed video on the one in your hand (best for indoor/moderate-size courts). - Shooting tools: grid lines, mirror, front/back camera, pinch zoom. - For saved clips: slow motion, frame-by-frame, still capture, and sharing. Quality - 1080p at 30 or 60fps. 60fps is great for fast motion like a golf swing. - Built to run stably even over long sessions. Pricing - Free to use (with ads). - A one-time purchase removes ads and unlocks longer delay and save-back, up to 180 seconds (120/180s). Buy once, keep it forever.
