Why Chicago Businesses Choose a Specialized App Development Partner

Chicago’s technology ecosystem has grown significantly over the past decade.

Frequently Asked Questions

How much does it cost to build a mobile app in Chicago?

Mobile app development costs in Chicago vary based on project scope and timeline, from a lean MVP to a full-featured enterprise application. Key cost drivers include platform choice (iOS-only vs. cross-platform), backend complexity, third-party integrations (EHR, payment rails, ERP), and custom UI design requirements. BitCot provides detailed fixed-scope estimates after a free discovery call, so you know exactly what you’re committing to before the project starts.

How long does it take to build a mobile app?

A focused MVP with one core user flow typically takes 8–12 weeks from signed contract to App Store submission. A mid-complexity product with multiple user roles and third-party integrations runs 16–24 weeks. Enterprise applications commonly take 6–12 months depending on scope. We publish a project timeline in the discovery phase so Chicago clients can plan around it.

Do you build apps specifically for Chicago's healthcare industry?

Yes. Healthcare is one of Bitcot’s core practice areas. We build patient portals, telemedicine platforms, clinical workflow apps, and EHR-integrated mobile products. Our team has direct integration experience with Epic, Cerner, and Allscripts — systems widely used by Chicago health systems, including Northwestern Medicine, Rush, and AMITA Health. Every healthcare engagement includes a dedicated compliance review phase before any PHI-adjacent feature is built.

Should I build a native app or a cross-platform app for my Chicago business?

The right answer depends on three factors: your users’ platform split (iOS-dominant vs. mixed), whether the app requires device-specific capabilities (ARKit, advanced Bluetooth, background processing), and your budget and timeline constraints. For most Chicago B2C apps and internal enterprise tools, React Native or Flutter delivers 90% of native performance at significantly lower cost. For apps requiring deep OS integration common in medtech and fintech native Swift and Kotlin is the better call. We make this recommendation explicitly in discovery, not as a default.

Do you offer app maintenance and support after launch?

Yes. Every app BitCot delivers includes ongoing maintenance and support. From OS update compatibility and performance monitoring to bug fixes and new feature rollouts, we keep your Chicago app stable, secure, and competitive long after launch.

Do I own the source code after the project is complete?

Yes, unconditionally. Full source code ownership transfers to you upon final payment. Bitcot retains no licensing rights, usage restrictions, or IP claims on any deliverable. You receive the full repository, build configuration, and deployment documentation everything needed to hand the project to another team or continue development in-house.
