iOS App Development Company in Dallas, TX
Native iPhone and iPad Apps Built the Way Apple Intended
Native iOS quality comes from architecture discipline, platform-specific UX standards, and careful performance engineering. DevZoni builds Swift and SwiftUI applications that feel truly native, scale cleanly after launch, and pass Apple’s quality expectations without unnecessary release delays.
Our Dallas team supports businesses across Plano, Frisco, Irving, and the wider DFW Metroplex with end-to-end iOS delivery from product discovery to App Store launch and post-release support.
Before Working With DevZoni
What iOS Teams Usually Tell Us
“Our app kept getting rejected in App Review because implementation details missed Apple’s guidelines.”
“After an iOS update, key features broke and the original codebase was difficult to maintain.”
“The app felt non-native to iPhone users and ratings dropped due to UX mismatch.”
“Cold start and runtime performance were poor, and no one had a plan to optimize.”

Frequently Asked Questions – iOS App Development
Simple iOS apps often start around $25,000 to $60,000. Mid-complexity products with backend integration commonly range from $60,000 to $120,000, while enterprise-grade iOS apps can exceed $100,000 depending on scope, security, and operational requirements.
Many focused iOS builds take 3 to 5 months. Mid-complexity products often require 5 to 8 months, and enterprise implementations can take longer. App Store review adds additional time depending on submission complexity and review feedback.
Native iOS is usually best when UX fidelity, advanced Apple framework access, and performance are core requirements. React Native is often suitable when a single codebase for iOS and Android is a priority. We evaluate the tradeoff by product goals and budget.
