PainChek(r) provides an app to allow non-verbal patients' pain-levels to be assessed.  It uses a smart phone to take a 3 second video which is then uploaded to the cloud and there assessed for micro-expressions indicative of pain.  The app is being used by care staff in a number of Residential Aged Care (RAC) facilities across Australia with overseas expansion underway.  The solution uses the typical SaaS model of a monthly fee based upon the number of beds in each RAC facility.

The latest quarterly update provided indicates an annual recurring revenue to 30 June 2019 of $587K.

The recent "pop" in the share price has come from the announcement by the Federal Government of a $5M grant to assist in the roll-out of the app across RACs in Australia.

Development of a couple of apps are underway to use the same technology to assess pain in 0-1 and 1-3 year olds.
