Codestreaks builds custom iOS and Android apps: cross-platform from one codebase, fast, and store-ready. Solid engineering first, with AI features like copilots, voice, and vision built in when your app needs them. Shipped by a US-based team in Austin, Texas.
Fixed-price scopes · Store-ready delivery · 100% code ownership
iOS and Android apps with agents, copilots, voice, and vision built in as core features, not afterthoughts.
React Native and Flutter apps that ship to both stores from one codebase, native where a feature demands it.
Add on-device and cloud AI to an app you already run, with evaluation and guardrails so accuracy is measured.
Have an app prototype that stalls in real use? We harden the architecture, AI, and store-readiness to ship it.

The intelligence in our apps runs on the same AI agents we develop. Build the product behind the app with AI SaaS development, reach users on the web with AI web application development, or embed an assistant with AI copilot development.
A mobile app development company designs, builds, and ships iOS and Android apps: the UX, engineering, backend, and store submission that take an idea to users. Codestreaks builds custom apps as fixed-price engagements, from concept to the App Store and Play Store, and adds AI features like copilots, voice, and vision when your app benefits from them.
We build cross-platform apps with React Native and Flutter so you get iOS and Android from one codebase, and go native (Swift, Kotlin) when a feature demands it. For AI features we combine on-device inference for latency and privacy with cloud models for heavier reasoning, choosing per feature rather than dogmatically.
Yes. We add agents, copilots, voice, vision, and personalization to existing iOS and Android apps, with the evaluation, guardrails, and logging that make AI features safe to ship. If your app already exists, we integrate without a rewrite; if the foundations are shaky, we tell you honestly.
A focused AI-powered app MVP typically ships in weeks, not months, because we scope the smallest version that proves the product and build it on production foundations. As a US-based mobile app development company in Austin, Texas, we work with startups and enterprises worldwide.
Tell us the app you want to build and the AI features you have in mind. We'll scope it and quote a fixed price.
