Sustained Use Over Short-Term Activity

Sustained use emerges when systems remain relevant over time, not when they force short-term attention. Activity spikes say little about value if they do not translate into stable routines.

Systems with this outcome respect users’ time, energy, and context. They create reasons to return without pressure or artificial stimulation. Use becomes voluntary, not coerced.

UX enables this by designing rhythm rather than stimulus maximization. Sustainability shows where use persists without constant prompting.
