Research Note
6 min read19 February 2026Building a gamified spending simulator
A useful research simulator has to feel engaging enough to finish, but structured enough to generate defensible data.
Design tension
If the product feels like a survey, completion drops. If it feels like a game with no constraint, the data becomes less useful.
SpendLens deliberately sits between those extremes. The interface needs to feel approachable while the underlying event model remains research-ready.
Core design principles
- Keep the session short enough to complete in one sitting
- Make budget consequences legible at every step
- Use prompts and triggers sparingly so they remain meaningful
- Return an interpretable final report instead of a vague score
