Toddle AI
Toddle AI is a privacy-first Android app that analyzes toddler walking videos on-device, checks capture quality, measures gait patterns from pose landmarks, and lets parents ask a local AI assistant to explain the result
Core trick
Runs pose-landmark gait analysis fully on-device through ExecuTorch on a phone NPU, with no cloud upload.

# ToddleAI  **On-device toddler gait observation — nothing about your child ever leaves the phone.**       🏆 **3rd place** — ExecuTorch Hackathon 2026 (Qualcomm × Meta), San Francisco, June 27–28, out of 30 teams selected from hundreds of applicants. --- ## What It Does You record a short, guided video of your toddler walking. ToddleAI checks the recording quality in real time as you shoot — if the feet aren't visible, the camera is shaking, or your child isn't walking side-on, it tells you exactly what to fix before you even stop recording. Once you have a good clip, it extracts step-by-step timing from the walk (step time, cadence, left/right symmetry) and compares them to published pediatric norms. You can then ask an on-device assistant to explain the results in plain language. Every step — video, pose estimation, gait math, and chat — runs locally on the phone; the app requests no internet permission. ## Demo A sample walking clip used for development and testing is included at [`video/Toddler_walking_in_blue_dre
