Not good result for action photo stacking

Try to capture action photo of my daughter and stack into 1 photo but result is blur picture. I even used tripod. Not only this app but also other 3 cant give a acceptable picture. I dont want to grip my dslr all the time and saw these app review on web so I gave those a try. If I want only bust mode I rather use in phone app for iPhone 6.

Altbzoeh about Burst Mode - High speed camera
