Design goal
The goal was to design a clear, rewarding habit loop for sustainable action: cue, routine, reward, and identity. Instead of overwhelming users with broad advice, EcoSlate gives one specific daily challenge, immediate feedback, and a streak worth protecting.
Core product decisions
Daily challenges create one binary eco-action per day, such as carrying a reusable bag or skipping a plastic straw.
Optional AI photo verification offers a 3× point multiplier, making accountability rewarding rather than mandatory.
Location-based nudges remind users near relevant moments, capped at respectful daily limits to avoid notification fatigue.
Streaks leverage loss aversion: “Don’t break your 12-day streak” becomes more powerful than simply earning more points.
Points, badges, and milestone rewards turn delayed environmental impact into immediate, meaningful feedback.
Key flow
The app journey moves from splash and onboarding into profile setup, permissions, routine setup, the home dashboard, challenge completion, optional photo verification, and rewards. Account creation appears after onboarding so users experience value before commitment.
Outcome
EcoSlate solves the intention-action gap by eliminating ambiguity, providing instant rewards, building repeatable habit loops, using streak protection, and helping users internalize the identity of someone who follows through on sustainable choices.
Success metrics
Engagement: daily active users, completion rate, streak length, and notification opt-in rate.
Retention: Day 7 / Day 30 retention, churn by cohort, and average days to a 30-day streak.
Behavior: photo verification rate, reward redemption rate, and habit diversification.
Final thought
“Small habits. Big impact.” is more than a tagline — it is the product philosophy. Small, specific, daily actions compound into lasting behavior change when the system makes sustainable choices feel clear, rewarding, and easy to repeat.
