Maintaining separate native apps and a website doubles your cost and splits your audience behind app store gatekeepers. We build progressive web apps that deliver native-app behavior from a single codebase, including offline access through service workers, push notifications for re-engagement, and home screen installation. This cuts app store friction and development cost compared to going fully native.
Using React, Next.js, Vue.js, and advanced service workers with smart caching strategies, we build fast PWAs that hold up across devices, browsers, and network conditions, including full offline functionality. Our builds target sub-second load times, strong Core Web Vitals scores, and high Lighthouse ratings, with the smooth animations, gestures, and transitions users expect from a native mobile app.
