Turning solo exercise into a social, habit-forming system — grounded in behaviour science and social psychology.
Fitness apps are full of features — but the dropout rate remains stubbornly high. Most people quit within weeks, not because they lack tools, but because exercise feels isolating and motivation fades without accountability.
The challenge wasn't building another tracking app. It was redesigning the social and motivational mechanics that make exercise feel worth continuing.
"How might we make fitness feel social, competitive, and rewarding — without adding cognitive overhead to an already demanding habit?"
Interviews focused on lapsed users, not active ones — understanding why people stopped was more valuable than understanding why they started.
Two archetypes emerged: the lapsed exerciser who needs accountability and the competitive athlete who needs worthy rivals.
Rival uses social mechanics, smart matching, and behaviour-informed feedback loops to transform exercise from a solo grind into a shared experience with real stakes.
A live social feed showing active sessions in progress — not just completed workouts. Turns passive tracking into active accountability.
Head-to-head challenges against matched rivals — not random users, but people at a genuinely similar fitness level. Competition that's close enough to be meaningful.
Milestones designed around behavioural psychology — rewarding consistency, streaks, and personal bests, not just volume. Progress that feels earned, not inflated.
Each decision reflects a specific insight about how humans actually build and break habits.
From competitive audit and user interviews through to high-fidelity prototyping — every stage fed into the next.
