About

InForm Motion Analysis

Features
Read full description

InForm is built around the way we actually train. - Film yourself, load a video from your phone, or use the integration with YouTube to capture the motion you want to study. - Quickly loop, slow down, and zoom in to highlight the exact sequence you are training. - Easily draw, annotate and measure angles. - Take notes and record your analysis and feedback directly in the app - Save, share, and track progress. As a dancer, weight lifter, rock climber, and dance teacher, I was always looking for ways to study movement. I always wanted a simple yet powerful video analysis tool that worked with how I trained and taught, but could never find the right one. So I decided to build InForm Motion Analysis. I believe that quality resources should be available to everyone who loves motion, regardless of finances. Therefore, InForm uses a donation-based model, which means it is FREE FOR ALL TO USE! No monthly subscriptions, no ads, no features hidden behind paywalls. All that I ask is that if you find InForm helpful, then please consider donating to support continued development and maintenance. A few features that make InForm especially powerful: - You can put a YouTube clip in one panel and your own video in the other to quickly master a sequence. - Easily compare before and after videos to see check progress, or use the project folders feature to track progress from one session to the next. - Write or record notes, or film a full coaching analysis in the app - Quickly save and share edited videos.
