96% user growth, 25% deposit increase — 19-month crypto fintech partnership

Results
'Tiers' lock-up feature design drove 96% increase in user growth (app downloads), directly contributing to platform adoption metrics.
'Debit Card' feature design resulted in 25% deposit increase, demonstrating measurable impact on platform revenue and user engagement.
Design system with 100+ components accelerated development velocity, significantly reducing engineering time and design debt across 19-month engagement.

About Ka.app (🇦🇪) (formerly Kasta) is a P2P crypto payment application enabling fee-free cryptocurrency transactions. As Lead Product Designer over 19 months, I designed and maintained the complete iOS/Android mobile app and desktop PWA platform for this late-stage fintech startup.
The engagement focused on scalable design systems and high-impact feature design — from token lock-up mechanics (Tiers) to integrated debit card functionality. Each feature was designed to drive measurable business outcomes: user growth, deposits, and platform adoption.
A playful, modern aesthetic balanced professionalism with crypto-native energy, supporting the app through App Store and Play Store launch before transitioning to standalone PWA. ✦ Scope/deliverables: - iOS/Android app design - Desktop PWA design - Design system (100+ components, 2000+ screens) ✦ Features / flows designed: Send, Receive, Swap, Deposit, Tiers (Token Lock-up), Debit Card, Cash/IBAN, Transaction History, Wallet Management, Onboarding,

"Novatur Design has been an integral part in preparing the Kasta application design for iOS and Android, with a strong focus on interface design and user experience. They are highly skilled in UI/UX design, with a deep understanding of design systems and high-fidelity prototyping. Kasta was fortunate for the collaboration, and the product would not be the same without their invaluable contributions."
