Other strobe photo apps require you to record video inside the app — TrailStack works with footage you already have. Sony MotionShot was discontinued in 2021. Clipstro is iOS-only and cannot import existing videos. Photoshop can achieve similar results, but takes 30–60 minutes of manual work per photo. TrailStack does it in seconds.

Tail Cam is a real-time camera effect that turns movement into flowing visual trails. The image is delayed row by row down the screen — the top updates instantly, while each line below shows a slightly older moment. The result is a smooth, continuous "tail" that follows anything in motion: a wave of the hand, a passing object, a turn of the head. Everything is processed live on your device, so you see the effect instantly in the viewfinder. FEATURES • Real-time time-displacement effect, rendered live on the camera feed • Smooth, continuous trails with no harsh stepping • Capture photos with the effect applied • Record video with the effect applied • Front and rear camera support • Clean, distraction-free interface HOW IT WORKS Point the camera at anything that moves and watch it stretch into a trail. Move slowly for gentle waves, or quickly for long, dramatic streaks. Tap to take a photo, or start recording to save a video — straight to your photo library. All capture and processing happens on your device. Nothing is uploaded, and nothing is shared.
