Mobile App Development From Empiric Infotech LLP
Empiric Infotech LLP is a remote mobile app development company for US companies that want one strong developer on their app month after month instead of a fixed-price build. Our developers work from India, and we have a US office in Bridgeville, Pennsylvania. Your developer writes the iPhone and Android app in Flutter, or in FlutterFlow where a visual build is faster, builds the backend behind it and takes the app through App Store and Google Play review, all inside your own accounts. A US app carries a US checklist. Apple expects an App Tracking Transparency prompt before any cross-app tracking and a privacy label that matches what the code collects. COPPA applies to apps aimed at children under 13, or that knowingly collect their data. Health features can fall under HIPAA, or under the FTC's Health Breach Notification Rule when HIPAA does not reach them. California and a growing list of other states let users see and delete their data, and accessibility claims under the ADA are common. We build for all of it from the first release. You get 2 hours live overlap, 8:00 to 10:00 AM ET (1 hour November to March), then a full day of work and a written handover. Roamate, a travel app founded by Charli Sharp, has run on a single dedicated developer from Empiric Infotech since launch and holds a 4.6/5 rating on both stores.
What our mobile app development company delivers for US companies
One developer on your app for the long run, building the parts that decide whether a US app gets approved, gets trusted and keeps its users.
Approval on the App Store and Google Play
Store review is where launch dates slip. Your developer prepares the App Privacy details and the Google Play Data safety form from what the code actually collects, adds the App Tracking Transparency prompt only if you track users across other apps, ships privacy manifests for the SDKs you use, and builds the in-app account deletion both stores require. When a reviewer pushes back, your developer handles the reply and the resubmission.
COPPA-ready apps for younger users
If your app is aimed at children under 13, or you know some users are under 13, COPPA requires verifiable parental consent before you collect their personal information, and the FTC tightened the rule in 2025. We build age screens, parental consent flows and data minimization into the product, and keep the SDK list within Apple's Kids Category and Google Play's Families policy limits on ads and analytics. Learning products sold to schools also need FERPA controls and LMS integrations, which our education app development service covers.
Health apps with HIPAA safeguards
When your app handles protected health information for providers or health plans, we build to HIPAA: encrypted storage, audit logs, role-based access and hosting under the business associate agreement you hold with your cloud provider. Wellness apps outside HIPAA can still fall under the FTC's Health Breach Notification Rule, so breach detection and logging go in either way. For workout, nutrition and coaching apps, see our fitness and wellness app development service, which adds HealthKit, Health Connect and Apple Watch work.
Accessibility to WCAG 2.1 AA
Screen reader labels for VoiceOver and TalkBack, Dynamic Type and font scaling, color contrast, generous touch targets and captions on video. WCAG 2.1 AA is the usual benchmark in ADA accessibility claims, and the Department of Justice made it the standard for state and local government apps in 2024.
Privacy rights under California law and other states
Access, deletion, correction and opt-out of sale or sharing, built as account settings your users can run themselves instead of tickets your support team handles by hand. The same flows serve the CCPA and the newer state privacy laws that follow its model.
Payments, push and builds overnight
App Store and Google Play billing for digital subscriptions, Stripe, Apple Pay and Google Pay for physical goods and services, and push notifications through APNs and Firebase. New builds land on TestFlight and Google Play internal testing while you sleep, so each morning starts with something to try.

How a US mobile app engagement starts
From the first call to a build on your phone inside a week, scheduled around US hours.
A call in your morning
Thirty minutes in your Eastern, Central or Pacific morning. You walk us through the app, the users, which platform comes first, and any date that matters, such as a launch, a funding milestone or a store deadline.
A written plan within 24 hours
What ships in month one, whether Flutter or FlutterFlow fits, which store and privacy items need attention, and an introduction to one developer who fits. You meet them first. The NDA and IP assignment are signed, and our W-8BEN-E goes to your accounts payable team.
A 7-day risk-free trial
Your developer starts within 48 hours and puts a first build on a real device during week one. Day 7 is a real decision point, with a full refund if the fit is wrong.
Monthly, invoiced in USD
One invoice a month, paid by ACH, wire or card. Standups in the Eastern-time morning, a written handover every day, and seven days' notice whenever you want to stop.
Mobile app development pricing for US companies
Both plans give you a developer who works only on your app, with a senior team lead who reviews and tests every build before it reaches TestFlight or the Play Console. Monthly covers 160 to 172 hours of full-time work, billed upfront in USD. Hourly suits a contained job, such as clearing an App Store rejection, adding a parental consent flow or moving to a new OS version. No setup fee and no recruitment fee.
Hourly plan
- A dedicated developer, exclusive to you while you have hours booked
- Pay as you go - billed by the hour, time tracked, a weekly report
- Best for short, defined work; no monthly commitment
- Code review and pre-delivery testing by a senior lead, built in
Monthly plan
- A dedicated developer, full-time and exclusive - 160-172 hours a month
- The best value for an ongoing engagement
- Your repo, your cloud account, your tools
- Code review and pre-delivery testing by a senior lead on every release
- 7-day risk-free trial, monthly billing, cancel with 7 days notice
Dedicated team
- A dedicated team - developers plus a senior team lead who reviews and tests every release
- Add a developer (and a designer where the build needs UI/UX work) at the same rate
- Best for long-term, multi-track work; add a developer in 48 hours, no re-contracting
The first 90 days of a US mobile app engagement
Dedicated work is ongoing, not a fixed project. This is the usual shape of the first quarter with a US product team.
- Week 1
Accounts, a running build and a first merged change
Access to your repository, your cloud and your App Store Connect and Play Console accounts, a build running on real iPhones and Android phones, and a first pull request reviewed and merged. Day 7 is the trial decision.
- Month 1
The core flow in testers' hands
Sign-up, the main feature and the data model, shipped to TestFlight and Google Play internal testing for your team. Crash reporting is live, and every change has been through code review and on-device testing.
- Month 2
Payments, push and the privacy answers
Subscriptions and checkout, push notifications, deep links and analytics. The privacy label, the Data safety form and any App Tracking Transparency prompt are drafted from what the app really collects, and features for children or health data get their consent flows.
- Month 3
Review, launch and the next quarter
Store submission, answers to reviewer questions, a phased release on the App Store and a staged rollout on Google Play. Your developer now knows the codebase well enough to propose work, and you plan the next quarter together.
A dedicated developer vs a US app agency, a contractor marketplace, or an in-house mobile hire
| Empiric Infotech (dedicated developer) | US app agency (fixed bid) | Contractor marketplace | In-house mobile hire | |
|---|---|---|---|---|
| What you pay for | A flat monthly fee per developer in USD, or hourly for a defined job | A fixed bid per phase; new ideas become change orders | An hourly rate per contractor, with hours you track | Salary (US median for software developers: $135,980, BLS May 2025), plus benefits and payroll tax |
| Store accounts and signing keys | Yours from day one: App Store Connect, Play Console, certificates | Often set up by the agency and transferred later | Wherever the contractor created them | Yours |
| Kids, health and accessibility rules | COPPA, HIPAA and WCAG work built into normal releases | Usually scoped and priced as extra work | Depends on the contractor's experience | Depends on who you hire |
| Time to start | 48 hours | Weeks: proposal, statement of work, kickoff | Days to weeks | Months of sourcing and interviews |
| Each new iOS and Android release | The same developer updates and resubmits the app | A maintenance retainer, or a new quote | Re-hire someone when the build breaks | Your team handles it, if they stay |
| Working hours | 2 hours live with ET mornings, then a written handover | Your hours | Varies by contractor | Your hours |
| Tax paperwork | W-8BEN-E provided; one monthly invoice | Per agency terms | A W-9 and a 1099 per contractor | W-2 payroll |
Each column describes how that option usually works, not any one provider. The salary is the median annual wage for US software developers from the Bureau of Labor Statistics (May 2025), before benefits and payroll tax.

Why US companies choose a remote mobile app development company
An app is never finished in the US market. Apple and Google change their privacy and review rules every year, iOS and Android ship a major release every fall, and regulators keep adding to the list, from the FTC's 2025 COPPA update to new state privacy laws. A fixed-price agency is built for version one: it delivers the build and moves its people to the next client, so every later change starts with someone new. Hiring in-house keeps the knowledge, but the median US software developer earns $135,980 a year (BLS, May 2025) before benefits and payroll tax, and most apps need iOS, Android and backend skills.
A dedicated developer keeps the context. The same person who built your onboarding and your subscription flow handles the next OS release, the next store rejection and the next feature. The time difference works the way it does for distributed US teams: a live standup in the Eastern-time morning, a full day of focused work, and a new build on TestFlight before your next day starts.
Roamate is the clearest example. A single dedicated developer from Empiric Infotech has shipped more than 20 versions of the app since launch, and it holds a 4.6/5 rating on the App Store and Google Play. You own the code, the store accounts and the data from day one, and you can stop with seven days' notice.

Frequently Asked Questions (FAQs)
It plans, builds, publishes and keeps improving apps for iPhone and Android, together with the backend, the admin tools and the store listings behind them.

With Empiric Infotech you pay a flat monthly fee per dedicated developer, in USD, for 160 to 172 hours of full-time work, or an hourly rate for a defined job. Current rates are in the pricing section above. For comparison, the median US software developer earns $135,980 a year (BLS, May 2025) before benefits and payroll tax.
2 hours live overlap, 8:00 to 10:00 AM ET (1 hour November to March), which covers a standup and anything that needs a conversation. The project manager is available until 1:30 PM ET. After the overlap your developer keeps building, and a written handover and a fresh TestFlight build are waiting when your next day starts.

You do, fully. The NDA and IP assignment are signed before work starts, and your developer works in your GitHub or GitLab organization, your cloud account and your store accounts from the first day, so nothing needs to be transferred later.
