Frequently asked questions about Mobile app development

We are an active partner to businesses in San Francisco and across the Bay Area, operating in a hybrid model that combines remote collaboration with in-person strategy sessions when needed. We're wherever your project needs us to be without the overhead of a downtown SF office baked into your invoice.

Most projects range from $5,000 to $50,000+, depending on complexity, platform, and feature scope. Startup MVPs typically fall in the $5,000 -$15,000 range, while enterprise-grade platforms scale significantly higher. We provide detailed, itemized estimates after a free discovery session, no guesswork, no ballpark figures.

A focused MVP can be live in 8–12 weeks. Full-featured consumer or enterprise apps typically take 3–6 months. We'll give you a precise, sprint-by-sprint timeline after scoping your project in our discovery session.

Both. A significant portion of our engagements involves modernizing, rescuing, or scaling apps that were built elsewhere. If your current app is underperforming, we'll diagnose exactly what's wrong and tell you the most cost-effective path forward, even if that means not rebuilding from scratch.

Yes. We can retrofit AI features, including conversational interfaces, recommendation engines, predictive analytics, and computer vision into existing applications without requiring a full rebuild. We scope this carefully to preserve what's working while adding intelligence where it creates the most value.

Yes. CCPA compliance is built into our development process by default, not added as an afterthought. We implement data minimization, consent management, and user rights workflows from day one for every California-based product.

Yes, this is one of our most common engagement models. We integrate as a seamless extension of your team, adopting your sprint cadence, communication tools, and code review processes. Many Bay Area companies use us to accelerate delivery without disrupting their existing engineering culture.

We offer tiered post-launch support packages covering monitoring, bug resolution, OS compatibility updates, performance optimization, and proactive feature development based on user analytics. We stay in the trenches with you long after launch day.
