The biggest difference is the destination.
Opal is built as a wider focus system
Opal’s current product language centres on Focus Rules. A free account can create one Rule using a schedule, time limit or open limit. Pro expands that into unlimited Rules, harder blocking, No Unblocks, advanced timers and soundscapes, Allow Only controls, and an Opal Score with history.
That breadth makes sense when distraction is not limited to parenting moments. A person may want one rule for social media, another for study, another for the workday and a stronger setting for a period that must stay protected. Opal gives those different contexts a shared system.
Hello Mumma is built around one repeating family moment
Hello Mumma deliberately narrows the job. You choose the apps that pull you away, protect the time that matters, and meet a real block when the automatic reach happens. The next screen does not leave an empty space. It gives you one small activity shaped around the children, the energy available and the ordinary things nearby.
The product’s advantage is not “more blocking.” It is that the interruption, the family activity and the reminder recorded by you all point toward the same outcome: being present for the person already in the room.
