I’m happy for someone to dispute me on this but I don’t personally think the children’s app will be a subscription/per month fee structure for the consumer version. Or certainly not $5 per month anyway. That would be a significant ongoing cost and a deterrent for many customers imo. Maybe $5 per child to be assessed by the app would be more reasonable (facial detection could make sure that assessments were only completed on children that had been paid for).

The commercial version (for hospitals, childcare etc.) would definitely be subscription however.
