US agencies quote $100–$250/hr, putting typical apps at $30K–$500K. Our mobile app developers deliver the same iOS, Android, and Flutter builds via our Delaware entity at $25–$60/hr — US-governed contracts, fixed pricing, your-timezone standups, and 1,200+ shipped apps behind every estimate. The offshore price without the offshore risk.

These are the real concerns we hear on every discovery call — here’s how we answer them, in writing, before you sign anything.
You’re not contracting overseas. Agreements run through our Wilmington, Delaware LLC under US-governed law — standard NDAs, MSAs, W-9, and IP assignment enforceable in US courts. Your attorney reviews a domestic contract, not an international one.
Hourly billing is where the games live — so we don’t play. Fixed price, milestone payments, written change orders only. You know the total before signing; rework from our mistakes costs you nothing. We profit by shipping, not by expanding scope.
Our delivery model is built around your clock: daily standups in EST/CST/PST overlap hours, direct Slack access to your engineers, and demos scheduled for US business hours. The offset becomes an asset — work progresses while you sleep, answers are waiting at your 9am.
You never take our word for it: staging access from the first month, live demos every two-week sprint, conversation logs on every test run, and a bot you can independently stress-test at any milestone. And our own chatbot SaaS — ChatLivo — is live today for you to judge before you sign anything.
We ship into the US market constantly: CCPA data handling, HIPAA-aware architecture for health bots, PCI-aware flows for payment conversations, data residency and retention policies — plus the platform review quirks (WhatsApp Business, Meta, Google) you only learn by surviving them hundreds of times.
The engineers in your proposal are the engineers on your project — named, with direct Slack access. Many are the same people who built and maintain ChatLivo. You’ll know within one sprint if that’s true, because you’re watching the work happen.
EmoTales is our own AI story-generator app — GPT-4 narratives, DALL-E 3 illustrations, in-app purchases, child-safety guardrails, and 500K+ stories generated. We scoped it, built it, passed Apple and Google review, and scale it today.
Most agencies show portfolios you can’t verify; we show a product you can install in the next 60 seconds. The same team, standards, and store experience go into your app.
iOS, Android, Flutter, AI features, modernization, and post-launch growth — everything US teams hire us to build, backed by 1,200+ apps shipped and our own live app on both stores.
Native Swift/SwiftUI apps built for the US market’s premium iPhone base — with StoreKit 2, widgets, App Clips, and the App Tracking Transparency compliance Apple review demands.
Native Kotlin apps handling the fragmentation of the US Android landscape — Play Billing, Material 3, and testing across the device profiles your users actually own.
One codebase, both stores, ~40% cheaper than dual-native — the default recommendation for most US startups. Exactly how we built EmoTales. Flutter service →
GPT-4/Claude assistants, image understanding, voice interfaces, and personalization — with API cost controls so unit economics survive scale. Proven in our own AI apps. GenAI service →
Inherited a troubled codebase? Honest audit first — what’s salvageable, what isn’t, with estimates — then incremental modernization without disrupting live US users.
Store submission for both platforms, listing optimization, crash monitoring, OS-update compatibility, and ongoing feature sprints on a flexible monthly retainer.
Don’t see your exact platform need listed? We’ve probably built something similar.
Our process is built to protect your timeline and budget at every stage — from the first call to App Store launch. Here is exactly what happens, and what you get at each step.
We map your app, users, and monetization on a call scheduled for your timezone. NDA available before anything proprietary is discussed. Fixed-price proposal with team names within 24 hours.
MSA and IP assignment under US-governed law, W-9 for your finance team, milestone payment schedule. Your attorney reviews a domestic contract.
A clickable Figma prototype of core flows in 1–2 weeks — investor-demo ready, user-testable, and the blueprint every sprint builds against.
TestFlight and internal-track builds on your phone from the first month, live demos in US business hours, direct Slack with the engineers writing your code.
Listing assets, privacy manifests, ATT compliance, review submission, and rejection handling for Apple and Google — we’ve been through review 1,200+ times.
Crash and analytics monitoring, OS-update compatibility, and feature sprints from real user data — on a monthly retainer you can scale up or cancel. Your code is 100% yours either way.
Ready to scope your app? Free 30-minute call, US hours.
Book Your Scoping Call →The technologies behind 1,200+ shipped apps — Swift/SwiftUI, Kotlin, Flutter, Node.js, PostgreSQL, and AWS/GCP — the same stack we use to build and run our own live products.
From scoping call to app store — a clear, staged build designed around US business hours, US contracts, and store-review realities.
We map your app, users, and monetization on a call scheduled for your timezone — then recommend the right platform (iOS, Android, or Flutter) for your actual audience.
A fixed-price proposal with named engineers, tech stack rationale, and timeline — delivered within 24 hours. NDA available before anything proprietary is discussed.
We draft the MSA and IP assignment under US-governed law, provide a W-9 for your finance team, and set a milestone payment schedule.
A domestic contract your attorney can review directly — no cross-border enforceability questions, no international legal exposure.
We build a clickable Figma prototype of your core flows in 1–2 weeks — designed around real user tasks, not generic templates.
An investor-demo-ready, user-testable prototype that becomes the blueprint every sprint builds against.
TestFlight and internal-track builds land on your phone from month one. Live sprint demos run in US business hours, with direct Slack access to the engineers writing your code.
A stageable build after every sprint and weekly written progress summaries — you always know exactly where the project stands.
We prepare listing assets, privacy manifests, and ATT compliance, then manage submission and rejection handling for both Apple and Google — we’ve been through review 1,200+ times.
A live app on both stores, plus a documented rejection-response playbook so future updates go smoother.
We monitor crashes and analytics, keep the app compatible with new OS releases, and ship feature sprints based on real user data.
A monthly retainer you can scale up or cancel anytime — and a codebase that’s 100% yours either way, with zero lock-in.
Step one starts with a free 30-minute scoping call — no commitment.

US market reality: $30K–$500K+ per app at $100–$250/hr, with dual-platform native builds at $120K–$400K. Our Delaware-contracted, Ahmedabad-engineered model delivers the same scope at the prices below — fixed, in writing, within 24 hours of your consultation.
From Delaware contracts to full code ownership — six real reasons US founders choose us beyond the rate card, backed by 1,200+ shipped apps and our own products.
Delaware LLC contracts, US-governed IP assignment, W-9, milestone billing — your legal and finance teams process a US vendor while your budget gets Ahmedabad engineering rates.
Download EmoTales before you sign anything. 1,200+ client apps plus products we run ourselves — quality you can install, not just read about in a portfolio PDF.
The 20–40% budget overruns that plague offshore projects come from hourly billing plus scope drift. Fixed pricing with written change orders makes overruns structurally impossible.
Daily syncs in EST/CST/PST overlap windows, demos in US business hours, and overnight progress waiting at your 9am. The time difference works for you, not against you.
ATT prompts, privacy manifests, IAP edge cases, rejection appeals — 1,200+ submissions of experience, including our own products, means your launch date survives review.

From MVP to App Store launch — here’s what US founders say after shipping their mobile app with Primocys.
We needed audio/video calls for patient consultations, live streaming for health seminars, and an Instagram-style photo/video feed for our medical community. Primocys delivered every feature, production-ready and on schedule. Their deep understanding of healthcare workflows stood out — they didn’t just build features, they built the right experience. Patient engagement and retention have grown significantly since launch.
Primocys developed my mobile application from scratch, handling everything from initial design to final deployment. They managed the entire project, demonstrating great flexibility by incorporating all my feedback and retakes. Beyond development, they successfully guided me through the App Store and Google Play submission process and are currently managing the app’s ongoing maintenance.
Our B2B and B2C platform helps Nigerian manufacturers sell at wholesale prices and suppliers offer competitive retail pricing, with a strong focus on Made in Africa products and easy local and international distribution. The app has received excellent user reviews for its design and unique features. Communication with the Primocys team was smooth in an agile setup, even beyond office hours when needed. Their mobile app development expertise is excellent—highly professional and reliable.
We hired Primocys to develop a highly complex and specialized mobile application, and they delivered outstanding results. The app includes advanced features such as timeline mixers, classifieds, payments, advertisements, GPS functionality, and more. Their technical skills, timely delivery, availability, and the personal attention Arpan Sagar brings to each project truly stand out. The team stays focused and committed from start to finish—an excellent experience overall.
The dating app was delivered successfully and approved by both Apple App Store and Google Play. Our users are highly impressed with the design, UI, and overall functionality. The project was well planned with clear milestones, and all modules were delivered on time. The team is talented, patient, and flexible, accommodating multiple scope revisions as requirements evolved. Their 24/7 development and support availability made the entire process smooth and reliable.
Great team with excellent communication and a strong commitment to on-time delivery. They developed a fully customized mobile app for both Android and iOS, perfectly matching our requirements. The entire process was smooth and professional, with clear updates at every stage. They are reliable, skilled, and very easy to work with. We’re continuing our partnership on more projects, and choosing them has been one of the best business decisions I’ve made.
