Appostrophe Tech Stack

iOS photo editing and design tools, expanding to web

Software Development Stockholm, Stockholm County 11–50 employees Privately Held

Appostrophe builds photo editing and graphic design apps for iOS, with active expansion into web. The stack spans native iOS (Swift, UIKit, Core Animation) and cross-platform mobile (Kotlin Multiplatform), paired with Node.js + AWS/GCP backends—a shape that reflects both the demands of performance-critical rendering (WebGL, Canvas API, C++) and the operational complexity of scaling across platforms. Current projects center on real-time sync, subscription systems, and a web backend for their 'scrl' product, while pain points cluster around rendering performance, memory management for large assets, and GPU efficiency—typical friction points when porting native mobile experiences to the browser.
