Overview
Spilk is an AI-powered app that analyses personal chats (WhatsApp, Instagram, Telegram) and turns them into emotional insights: response times, conversation balance, mood patterns.
The product had real analytical power but an interface that hid it. My work covered the complete app redesign: a calmer onboarding, a legible data-visualisation language and a refreshed brand.
Challenge
Chat data is intimate. The previous experience asked for trust before it earned it: dense screens, unclear charts and an onboarding that explained too little, too late.
- Users didn’t understand what the app would do with their conversations.
- Insight screens read as raw statistics rather than stories.
- The visual identity felt technical, not personal.
Approach
Onboarding that earns trust
The new flow greets users personally (“Hey! Olivia and Marta”) and explains each step of the analysis before asking for anything. Privacy language moved from fine print to first screen.
Data as narrative
Response-time arcs, weekly rhythm rings and side-by-side comparisons were redesigned around one principle: every chart should answer a human question, like who replies faster, and is that changing?
A warmer brand
Deep violet grounds the interface; coral and soft lilac carry the data; a rounded wordmark makes the product feel like a companion rather than a lab.
Outcome
Trust made visible
Privacy explained upfront; consent became part of the experience, not a hurdle.
Charts people read
Usability sessions confirmed users could interpret every insight without help.
A brand with warmth
New identity carried consistently across onboarding, data and marketing screens.
