ONE TOOL, MANY MOMENTS

From quick everyday math to figures needed at work, our days contain more moments of calculation than we realize.
This project began with a simple question: how can those moments stop being interrupted by switching between multiple apps?

UNIFIED EXPERIENCE DESIGN

Previously fragmented calculation tasks—basic arithmetic, unit conversion, currency exchange, VAT, BMI—were reorganized into a single, continuous experience.
By designing the information architecture and screen flow around intent rather than features, users can focus on executing the calculation they need immediately, instead of choosing which tool to open.

VISUAL SIMPLICITY, FUNCTIONAL CLARITY

Warm-toned colors and clear contrast distinguish input areas from results at a glance.
While the app supports complex functionality, the UI remains light and calm—establishing a design standard that minimizes fatigue even with frequent, repeated use.

GROWTH-READY CREATIVE SYSTEM

Advertising creatives were developed in alignment with the app’s UX, built around a clear message: calculation, solved in one place.
Rather than listing features, the visuals focus on real usage moments—allowing the core value of All in One Calculator to be understood instantly and scaled consistently across campaigns.
