As the fitness industry continues to grow and evolve, developers are looking for innovative ways to create engaging apps that keep users motivated and active. With the rise of Windows-based devices, it's essential for app creators to ensure their applications run seamlessly on this popular platform. In this article, we'll explore how Microsoft's App Assure team is helping developers accelerate arm momentum in Japan and globally.

In today's fast-paced world, customers demand more from their devices than ever before. Arm-powered Copilot+ PCs have revolutionized the way people work and play by delivering industry-leading performance, breakthrough battery life, and advanced AI acceleration. With these benefits comes a new level of responsiveness and capability, making complex tasks faster and smarter.

As developers bring optimized experiences to market, they're recognizing the value in embracing Arm-powered devices. Microsoft's ongoing investment in this innovation ensures that customers can trust their essential apps to run reliably on Windows on Arm. A key part of delivering this experience is App Assure, a team dedicated to helping developers validate compatibility and address technical blockers.

While App Assure's efforts span the globe, a region of particular focus is Japan, where collaboration with Microsoft's regional teams, software development companies (SDCs), and academic partners helps identify and prioritize the applications most critical to local customers. By working closely together, these organizations are driving innovation and adoption forward.

PFU: Building Native Drivers for ScanSnap

In May, PFU Limited approached App Assure to accelerate their efforts in preparing one of their flagship products, ScanSnap, for Arm. Through a sprint of focused collaboration, the teams worked together to enhance the user experience and ensure a smooth release. The results were highly impactful, with driver improvements completed early and seamless progress toward Arm compatibility.

PFU's commitment to delivering an end-of-year release for ScanSnap was made possible through App Assure's best-practice architectural guidance and hands-on engineering support. This engagement not only delivered Arm support but also strengthened PFU's alignment with Microsoft, created new opportunities for future business growth, and demonstrated the power of collaboration in addressing both technical and organizational challenges.

Saito-Kikaku: A Legacy of Reliability

App Assure also worked with Saito-Kikaku, an influential software vendor behind the Hidemaru Editor, a text editor that's been a staple in Japan for over 30 years. By using Prism, the new emulator built into Windows 11, Saito-Kikaku was able to automatically translate x86/x64 instructions into Arm64 instructions without making any code changes or rebuilds.

Testing results were impressive, with Takashi Yamamoto, lead developer at Saito-Kikaku, stating that "there were absolutely no problems. It just worked." This experience gave Saito-Kikaku confidence and reassured customers that their trusted editor would run smoothly on Copilot+ PCs.

Arm Momentum is Global

What's happening in Japan mirrors trends around the world: As developers validate their apps for Arm, they're discovering that enablement is often smoother and faster than expected, and that it opens their apps up to a growing audience hungry for AI-powered experiences. Consumers benefit from the industry-leading performance of Arm-powered Copilot+ PCs with the confidence that the apps they rely on will work flawlessly on their new devices.

App Assure will continue supporting this momentum by helping developers ensure their apps run seamlessly on Windows on Arm, today and into the future. Whether you're an SDC evaluating Arm support for the first time or a customer relying on mission-critical applications, we're here to help empower your fitness app development journey on Windows.
