I build production iOS and macOS apps for startups and small teams. I focus on AI-native apps that run on the device. That means fast responses, lower cloud cost, and better privacy for your users.

We follow Apple standards for privacy, AI, and release quality. See Core ML, Foundation Models, App Privacy Details, and App Store Review Guidelines.
Built on
8 iOS apps & 4 Mac apps shipped on the App Store
Architecture audits completed in under 5 business days
100% on-device AI — zero cloud dependency
SwiftUI MVPs delivered in 4-week sprints
Real systems delivered in production. From complex business platforms to developer tooling.
I work with specific types of teams and projects. Clear fit means better outcomes.
Fixed-scope services with clear outputs, clear timelines, and senior-level execution.
We review your app and show what to fix first. You get a clear roadmap, AI readiness notes, and practical next steps. Think of it like a structural survey before a renovation.

5 business days · Async-first, one live session
→ Prioritized technical roadmap
We build the first production version of your app in one focused sprint. You get a strong SwiftUI foundation, data sync, and an App Store-ready build. Think of it like building the frame of a house before adding rooms.

6–8 weeks · Sprint-based, async collaboration
→ App Store-ready iOS/iPadOS app
We add private, on-device AI to real products. Models run locally, so your app stays fast and user data stays on the device. Think of it as hiring a smart assistant that never sends notes to an outside server.

Real systems built through 3NSOFTS. Problem → System → Outcome. Real numbers from real deployments.
Offline-First Operations Platform
Problem
SMEs juggling spreadsheets, messaging apps, and paper notes for inventory and dispatch.
System
Native iOS/iPadOS app with Core Data + CloudKit. Works offline first and syncs for smooth team collaboration.
Outcome
Consolidated 3 fragmented tools (spreadsheets, messaging, paper notes) into one offline-first iOS/iPadOS app.
Developer Tool
Problem
iOS developers lose hours fixing Xcode config issues. These issues can cause build failures and App Store rejections.
System
Native macOS app that runs 9 focused checks in under 2 seconds. Analysis is read-only.
Outcome
Catches Xcode configuration errors before they cause damage. Prevents App Store rejections and build failures.
Offline AI Assistant
Problem
Some users need AI with no internet and no privacy trade-offs.
System
The app uses Apple Intelligence. It runs entirely on-device — battery-aware, no cloud.
Outcome
100% offline AI inference using Apple Intelligence and Neural Engine. Critical for emergency and off-grid scenarios.
“3NSOFTS consolidated three disconnected tools into one iOS workflow and cut our coordination overhead by 65% in the first month.”
“Their architecture and tooling recommendations now save our team 4 to 6 engineering hours every time Xcode breaks a build pipeline.”
“The on-device AI architecture gave us 0-byte external data transfer and extended battery life by 40% for emergency use cases.”
Industry Context
“Apple Intelligence is the personal intelligence system for iPhone, iPad, and Mac. It draws on your personal context to give you intelligence that's most helpful and relevant to you. Privacy protections are built in from the ground up.”
3NSOFTS builds production apps on this exact infrastructure. We use Apple Foundation Models, Core ML, and Apple Intelligence to ship AI features that run without a cloud connection.
Why teams choose 3NSOFTS when they need reliable systems, not quick demos.
Your app works even when signal drops. Data saves locally first, then syncs in the background.
We run AI on the device, not in the cloud. That keeps features fast and private.
We build SwiftUI code that scales beyond a prototype. Teams can add features without rewrites.
We optimize for the next 12 months, not only for launch week.
