IMPACT
Significant Performance Improvements
Running natively on Arm delivers faster load times, smoother interactions, and more responsive behavior—solving the lag and inefficiencies seen in the emulated version.
Better Power Efficiency and Battery Life
Thanks to the energy-efficient Arm architecture, the app consumes less power, helping to extend battery life on laptops without sacrificing performance.
Faster Development and Easy Transition
Flexibits transitioned Fantastical to Arm in about three months, proving that moving to Arm can be quick, straightforward, and highly rewarding.
TECHNOLOGIES USED
Intelligent Features Powered by AI
To bring the Arm-native version of Fantastical to life, Flexibits leveraged a powerful combination of technologies and tools. The app’s intelligent features are powered by robust AI and machine learning models, including natural language processing (NLP) for intuitive event creation—one of Fantastical’s most popular innovations that continues to set it apart in the productivity space.
Optimized Performance with Windows on Arm
On the development side, the team utilized the Arm compute platform and the Windows on Arm developer toolchain to optimize performance and efficiency. Flexibits also leveraged cross-platform frameworks and seamless dependency integration. With the right testing hardware and native development kits, they ensured a smooth transition from emulated performance to a native experience that runs faster, uses less power, and delivers an enhanced user experience on Arm-based PCs.
