The product
Previx is made for construction teams. Every day the app asks one question from a bank of more than 2,000, across twelve themes: first aid, protective equipment, work at height, electricity and more.
Correct answers earn points, streaks reward coming back, and from 200 points the points turn into vouchers and discounts. Feedback loops, streaks and reward tiers: game design, applied to safety on site.
What the app does
- A question a day
- A reminder at the time each person chooses, quiet at weekends, with notifications that work offline.
- Progress
- Streak, active days and score, readable at a glance.
- Rewards
- Vouchers, discounts and a team pot, unlocked in progressive tiers.
- Content
- Questions checked by construction professionals and updated regularly, free for the people who answer them.
The website
previx.fr speaks to both sides of the audience: the workers who download the app, and the companies that roll it out across their teams, with a section of its own for employers and a direct link to Google Play.
The page shows the product the way it is used: a phone with the question of the day, the current streak, the points just earned. Two minutes a day is the promise, and the page keeps it short too.
