Ein-Des-Ein (https://ein-des-ein.com), a full-cycle web and mobile app development company, today announced the launch of CashPilots, a gamified rewards platform now available on both iOS and Android. The release marks the completion of a cross-platform build delivered using Kotlin Multiplatform (KMP), enabling shared business logic across both operating systems while tailoring each app to its native environment.
CashPilots allows users to earn a digital currency called PilotMiles by completing everyday activities such as playing games, taking surveys, reading articles, trying new apps, and shopping through partner offers. Users can then redeem accumulated PilotMiles for cash, digital gift cards, travel rewards, and sweepstakes entries.
The client approached Ein-Des-Ein with a defined product vision and user journey, and required a scalable, high-performance implementation for both mobile platforms. By adopting Kotlin Multiplatform, the Ein-Des-Ein team built shared business logic once and adapted the presentation layer for each platform, reducing development time and cost while accelerating time-to-market.
“Our focus was on turning a clear client vision into a stable, scalable product that feels effortless for end users,” said Michael Chepurniak, CEO of Ein-Des-Ein. “Kotlin Multiplatform let us deliver a consistent experience on iOS and Android without compromising native quality.”
The completed app features a modular, maintainable architecture designed for long-term scalability, smooth animations, fast screen transitions, and stable handling of backend data. The unified reward system consolidates multiple earning mechanics into a single interface, with a redemption flow that lets users convert PilotMiles into rewards in a few taps.
Founded more than six years ago, Ein-Des-Ein is a digital product studio with offices in Warsaw, Poland and Vienna, Austria, a team of more than 50 specialists, and over 100 delivered projects across industries including fintech, healthcare, iGaming, SaaS, and AI.
