Choose one track or combine them — our senior team ships mobile, web, desktop and design with the same fixed-price, async process. Explore mobile, web, desktop & design, or see work and pricing.

  • Mobile App Development — Swift, Kotlin & Flutter

    We build native and cross-platform mobile apps for iOS and Android using Swift, Kotlin and Flutter. Whether you need a consumer app, field-team tool or companion for your SaaS, we handle product strategy, UI prototyping, API integration, offline-first storage, push notifications and App Store and Play Store submission. Our senior team ships an MVP in 4–6 weeks with bi-weekly demos, then iterates based on analytics and user feedback. Every line of code lives in your GitHub from day one, so you own 100% of the IP. See our process and recent work for examples of 4.8-star apps with 500k+ users.

  • Web Application Development — React & Next.js

    Our web app team creates fast, scalable products with React, Next.js, Node.js and Python. From SaaS dashboards and admin panels to Progressive Web Apps and marketplaces, we focus on performance, SEO and maintainability. We design component systems in Figma, implement server-side rendering where it matters, build secure APIs and set up cloud infrastructure that scales with your users. Ideal for founders validating an idea or enterprises modernizing a legacy portal, each sprint is fixed-price with demos every two weeks. Explore our pricing and process to see how we launch reliable web platforms that support 500k+ monthly users.

  • Desktop App Development — Electron & Tauri

    For teams that need power beyond the browser, we develop offline-first desktop applications for Windows, macOS and Linux using Electron and Tauri, plus .NET when required. Think inventory managers, data tools and healthcare clients that must work without internet and sync later. We optimize for speed, native OS integration and small installer size, handling auto-updates, licensing and analytics. Like all services at we2app, you get a senior-only team, transparent fixed-price sprints and code you fully own. Check our work and contact us to discuss how a desktop companion can cut workflow time by 40%.

  • UI/UX Design & Prototyping

    Great apps start with clear UX. Our UI/UX design service covers user research, journey mapping, wireframes and high-fidelity prototypes in Figma before any code is written. We create reusable design systems, brand guidelines and clickable demos you can test with real users to validate assumptions early. This reduces rebuild costs and speeds up development for mobile, web and desktop products. Whether you need a full rebrand or just a design sprint before development, we provide async collaboration, quick iterations and a hand-off developers love. Start with design then seamlessly continue to build with our engineering team via our contact process.
