iPhone-first quality
iPhone holds a large share of US smartphones, so iOS design, performance and App Store review readiness get extra attention, with Android tested in parallel.

Mobile app development company for US businesses
InnoFeature Labs builds iOS, Android and cross-platform apps for small and mid-sized US businesses: field service and dispatch apps, delivery and route apps, customer booking apps, and mobile access to your ERP, CRM or QuickBooks data.
We plan for what US buyers and app reviewers check: iPhone-first polish, state privacy laws, accessibility and, for health apps, HIPAA safeguards.

In short: We are a mobile app development company working with US businesses. We design, build and publish iPhone and Android apps, connect them to the systems you already use such as QuickBooks, Salesforce or a custom ERP, take payments through Stripe, Apple Pay and ACH, and design for state privacy laws such as the CCPA, accessibility and, where needed, HIPAA.
US
What a US app has to get right
The US has no single privacy law and app users expect iPhone-level polish. These are the points we design for on US projects.
State privacy laws
California's CCPA/CPRA and a growing list of state privacy laws require clear notices and opt-outs. Apps used by children under 13 must follow COPPA.
HIPAA for health apps
Apps that handle protected health information for covered entities need HIPAA safeguards: encryption, access logs and cloud providers that sign a Business Associate Agreement.
Accessibility
Accessibility claims under the ADA are common in the US. We design to WCAG 2.1 AA: screen-reader labels, dynamic text and sufficient contrast.
US payments
Cards, Apple Pay and Google Pay through Stripe, ACH bank payments for B2B, and sales tax calculated by tools such as Stripe Tax or Avalara.
Your existing tools
Two-way sync with QuickBooks, Salesforce, HubSpot or a custom ERP, so the app is not another island of data.

Frequently asked questions
FAQs
Do you build apps for US businesses?
Yes. We work with small and mid-sized businesses across the United States. Discovery, design reviews and sprint demos run online and are scheduled to overlap with US business hours.
How much does it cost to build an app in the US?
It depends on screens, user roles, native or cross-platform, offline needs, payments and integrations. We define a first release in discovery and estimate it in USD before development starts.
Can you build HIPAA-compliant apps?
We build health apps with HIPAA safeguards: encryption in transit and at rest, access controls, audit logs and hosting with providers that sign a Business Associate Agreement. Compliance also depends on your own policies, so we work with your compliance lead.
Can the app connect to QuickBooks or Salesforce?
Yes. We connect apps to QuickBooks Online, Salesforce, HubSpot and custom ERPs through their APIs, so orders, customers and invoices stay in sync.
Should we build iOS first?
For many US consumer apps, launching on iPhone first makes sense because of iPhone's large US share. For staff apps on company Android devices, Android or cross-platform may be better. We decide this with you in discovery.
Who owns the app and source code?
For custom builds the deliverables become your property after full payment unless agreed otherwise in writing, and apps are published under your own Apple and Google developer accounts.
