It depends on the project scope. A simple MVP can take 4-6 weeks, while a comprehensive app may take 3-4 months. We work in agile sprints, delivering a working build every 2 weeks.

An MVP is the first version with a minimum feature set to test your core value proposition. It evolves into a full product through user feedback iterations. Shipping early is more valuable than shipping perfect.

We integrate AI models via OpenRouter for text and language capabilities, and fal.ai for image and video generation. We pick the best model for each use case, balancing quality, speed, and cost.

Our team stays up-to-date with Apple's guidelines and proactively manages the review process. In case of rejection, we provide quick fixes and re-submit within 24-48 hours on average.

We help you choose the right strategy from subscription, freemium, one-time purchase, or ad-based models. With RevenueCat integration and ASO, we build sustainable revenue channels tailored to your product.

Yes. We offer long-term partnership with bug fixes, iOS update compatibility, performance optimization, and new feature development.
