Design notes

Opal treats focus as a deliberate, almost ceremonial action. Dark surfaces, luminous accents and distinctive visual metaphors make an invisible goal feel concrete.

Its interface is worth studying for behaviour-change products: mood and reward are integrated into the experience of setting boundaries, rather than left to decorative marketing screens.
