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. Download TrailStack and see your movement in a whole new way.

Verdict
The clearest difference is ads: AR記念看板 at none against TrailStack's shown. AR記念看板 also leads on iOS requirement (11.0 vs 13.0). TrailStack's advantage is update cadence (daily vs every 3 months). On price, in-app purchases and device support there is nothing between them.
