The Challenge
The Challenge
How might we design a solution that makes splitting bills simple, fair, and stress-free, while also integrating with India’s preferred payment methods? Users need more clarity in error handling, flexibility in splitting, and a faster way to settle dues.
Goal: Design a mobile-first solution that makes splitting bills simple, transparent, and UPI-first, while reducing social awkwardness.

Research & Insights
Research & Insights
Methods: User interviews, Competitive Analysis and Affinity Mapping
Surveyed & interviewed 5 participants (students, professionals, social spenders).
Built User Personas reflecting different needs (simplicity, transparency, trust).
Key Pain Points:
Awkwardness in reminding friends.
Confusion in itemized/unequal splits.
Switching apps for payments.
Lack of clarity when errors occur.
Key Takeaways
Users want seamless group creation without extra steps.
Error handling must be clearer and action-driven.
Direct UPI integration is a must-have differentiator.
Transparency (seeing the bill, who owes what, and how it’s calculated) builds trust.

The brand choices communicate trust, simplicity, and friendliness, with a modern, approachable tone. Core UI elements such as buttons, navigation bars, toggles, and checklist states were designed as reusable components, making it easier to scale the product while keeping the experience cohesive.

Reflection

Working on Tally taught me the importance of designing for context-specific needs. In India, UPI integration isn’t just a nice-to-have feature, it’s a necessity that drives adoption and trust. I also learned how small UX decisions—like clearer error alerts, auto-selecting members in equal splits, and placing confirmation messages at the right stage—can make a significant difference in user confidence and satisfaction. Conducting usability testing early, even with low-fidelity wireframes, proved invaluable for uncovering pain points that shaped the final product.
Looking ahead, I see opportunities to expand Tally with features like recurring expense tracking, spending analytics, and dark mode for accessibility. A real-world pilot with small friend groups would also help validate adoption and provide insights for further refinement.
