Frequently Asked Questions

What iOS app development services does Space-O Technologies offer?

We provide many iOS app development services, including custom iOS app development, UI/UX design, app testing and quality assurance, and API development and integration. They also provide post-launch maintenance support, iWatch app development, and iOS consulting services.

How long does it take to develop an iOS app?

The timeline depends on the app’s complexity and features. A basic app may take 2–4 months, while a more feature-rich or enterprise-level solution could take 6–12 months. After the requirement analysis, we provide clear project timelines.

Can I get an MVP (Minimum Viable Product) before full-scale development?

Yes, Space-O Technologies provides clients with an MVP before full-scale development. We understand that deploying an MVP helps bring the app to market early, analyze demand, and gather constructive feedback from users to fine-tune the final app and meet expectations.

Do you offer support after the app is launched?

Yes, we offer three months of post-launch support, which includes performance monitoring, bug fixes, and security updates. Based on your needs, ongoing maintenance packages are also available.

What security measures should I expect from your company?

During the iOS app development cycle, we follow Swift and Objective-C security best practices to ensure a bug-free codebase with zero vulnerabilities. We incorporate features like MFA (multi-factor authentication) and stringent authentication mechanisms like OAuth to enable secure logins and prevent identity theft. For stronger network security, we implement HTTPS for secure network communications and firewalls to make the backend server unbreachable.

How much does Space-O Technologies charge for iOS app development?

Although iOS app development costs largely depend on the app’s complexity, features, and technology stack, we can provide a brief estimate based on complexity. For basic iOS app development, our charges range from $20k to $50k, while moderate complexity apps can cost up to $150k. A highly sophisticated app may cost more than $150k.

How involved will I be during the development process?

We keep you in the loop with regular updates, demo sessions, and milestone reviews. Your feedback is integrated at every stage, ensuring we build exactly what you need.
