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. PRIVACY FIRST All processing happens entirely on your device. We never upload, store, or transmit your photos or videos to any server. What's on your phone stays on your phone. FREE & FAIR TrailStack is free to download and use. Exports include a small watermark. Watch a short optional ad to save a watermark-free version at any time — no subscription, no hidden fees.
