About
Ergo Assess turns your iPhone into a workplace ergonomics tool. Film someone doing a task and a posture skeleton is drawn over them as you record, with RULA and REBA scores that update as they move. The analysis runs on the phone itself.
RECORD AND SCORE
• A live posture skeleton with RULA and REBA scores while you film
• Light (lux) and background noise (dB) readings alongside the video, as an indicative guide
• Front or back camera, with the video or the skeleton hidden whenever you like
• Import a video or photo you already have and score it the same way
REVIEW EVERY MOMENT
• Replay the recording with the skeleton, a risk timeline and a body map
• Jump straight to the worst moment
• Minimum, average and peak RULA and REBA scores for the whole task
• NIOSH lifting analysis for lifting tasks
• Add operator details and capture the operator's consent signature on the spot
SAVE AND SHARE
• Save recordings on your iPhone and reopen them later
• Share the clean video, the pose data (Landmarks JSON) and 3D motion (BVH) where it was captured
• Sign in with your Universal ID to send a recording, with its operator details and consent signature, to the Ergo Assess web app for more methods, including OWAS, ROSA, QEC and the Strain Index, and PDF reports
LEARN THE METHODS
A built-in knowledge base explains RULA, REBA, NIOSH and twelve more ergonomic methods: how each is scored, its risk levels, when to use it and its limits. It works without a connection.
TRY IT FIRST
Open a sample assessment to explore the results, replay and exports before recording your own. You don't need an account to record, score and save on your iPhone.
YOUR DATA
Recordings stay on your iPhone unless you choose to send one. The microphone only measures how loud the room is; no audio is recorded. No adverts and no tracking.
Ergo Assess supports a competent assessor's judgement. It isn't a medical device and doesn't give medical advice.
