İstanbul Yazılım

Istanbul, Turkey

Mobile apps, websites and custom software from Istanbul, since 2014

İstanbul Yazılım is a software agency in Istanbul that builds mobile apps, websites and custom software for startups and growing businesses. Since 2014 we have taken products from idea to the App Store, Google Play and the web. We build iOS and Android apps from a single React Native codebase, backends with Node.js and NestJS, admin panels and Next.js websites, and we handle store publishing end to end. Every project starts with a written scope listing each screen, a timeline and payment milestones. Clients test working builds throughout, and the source code, servers and store accounts are set up in their name. Recent work includes Barnerobe, a second-hand marketplace for parents in Norway; Tinnimizer, a tinnitus therapy app in 13 languages; Kısmet Kapısı, a dating app with verified profiles; AutoFikir, a classifieds app and website; and Pedalog, a parenting app connecting parents with experts.
