TIPS FOR GETTING THE BEST RESULTS: 1) Keep the camera as still as possible. In cases where the camera needs to follow an action, move the camera slowly and no more than 45 degrees. 2) The background should be distinctive. Water, snow, or sky backgrounds will likely not produce desired results. Also, avoid dark places. 3) Because actions performed in place will overlap, objects and actions being recorded should move across the video frame.

Verdict
The clearest difference is price: TrailStack at Free against Clipstro's $3.99. TrailStack also leads on update cadence (daily vs every 3 weeks). Clipstro's advantage is ads (none vs shown) and iOS requirement (8.0 vs 13.0). On in-app purchases and device support there is nothing between them.
