Istanbul Yazilim

Istanbul Yazilim is a software agency based in Istanbul, Turkey. Since 2014 we have helped founders and companies turn ideas into products people use every day. Our focus is mobile apps, and we also build corporate websites, e-commerce platforms and custom software.

We build iOS and Android apps with React Native from a single codebase, backends with Node.js and NestJS, admin panels and Next.js websites. We handle payments, subscriptions, push notifications, messaging and video, and take care of App Store and Google Play publishing, including privacy declarations and Google Play closed testing.

Every project starts with a written scope listing each screen, a timeline and payment milestones. Clients see working builds throughout the project. Source code, servers and store accounts are opened in the client's name. After launch we stay on for maintenance, OS updates and new features.

Selected work: Barnerobe (second-hand marketplace for parents in Norway), Tinnimizer (tinnitus sound therapy app in 13 languages), Kismet Kapisi (marriage-focused dating app), AutoFikir (classifieds marketplace app and website) and Pedalog (parenting app connecting parents with child development experts).
