Native and cross-platform apps for iOS and Android
From idea to the App Store — we’re with you the whole way
Mobile app development services cover the design, build, and release of native and cross-platform applications for iOS and Android. TreeSoop has shipped mobile apps across industries — construction safety monitoring, AI shopping, group dating — using React Native and Swift, delivered by a team of KAIST and POSTECH engineers with a 4.92/5 rating on Wishket, Korea’s largest dev-outsourcing platform.
You have a web service but no mobile app, so users drop off — yet developing iOS and Android separately doubles both the cost and the timeline.
Building without a solid grasp of app store guidelines leads to repeated rejections — or low post-launch ratings that quietly bury your app in search results.
After the initial build, each added feature bloats the app, slows rendering, and drains battery — pushing user churn higher and higher.
We build React Native apps that support iOS and Android from a single codebase, sharing code with your web team to keep development costs to a minimum.
When the product depends on native iOS capabilities — camera, AR, high-performance graphics — we build fully native iOS apps in Swift.
FCM and APNs push notifications, WebSocket realtime updates, and background task handling — apps engineered to keep users coming back.
Development that complies with App Store and Google Play review guidelines, plus app store optimization (ASO) to maximize launch success and organic discovery.
User journey maps, wireframes, and prototypes lock in the app structure and core flows.
A design system that follows platform guidelines (HIG / Material Design) and polished, production-ready screen designs.
Feature-by-feature sprint development with transparent progress sharing, securely integrated with backend APIs.
Real-device testing, performance profiling, and battery and memory optimization ensure stable app quality.
We handle store review, monitor crashes after launch, and ship fast updates driven by user feedback to keep your app growing.
A worker-safety monitoring app for construction sites, built natively in Swift with AI hazard-detection alerts, realtime location tracking, and incident reporting
An AI shopping app that lets users virtually try on glasses via YOLO v11 face recognition, combining camera AR with integrated commerce
A group-matching dating app built on Swift and Django, with group profiles, a matching algorithm, realtime chat, and safety verification
