The habit loop that brings customers back.
Daily challenges, games, streaks, quick actions, achievements, leaderboards, and referrals. The behavioural science that made Duolingo a habit, reshaped for your storefront — so customers have a reason to show up every day, not just when they need to buy.

Rewards your customers actually want.
Points, XP, tiers, and rewards orchestrated as one economy. Stop training customers to wait for discounts — give them status, access, and real value instead. Every mechanic is tuned by the four principles that actually work: variable schedules, loss aversion, goal gradients, and the endowment effect.
