Mobile App Development Company in San Francisco

San Francisco teams understand startup pressure because they work in it daily. They’ve shipped apps that got funded as well as apps that failed badly. So, you’re not just hiring developers; you’re hiring experienced creators. Why choose Apptunix? Here are some reasons:

• Direct access to your team, no time zone delays ever.
• Investors and early adopters test your app continuously.
• They’ve made every mistake, so you don’t have to.

The price changes the moment you add one feature. Basic apps cost $20K to $70K for launch. Mid-range with databases and APIs runs from $70K to $150K. Complex with AI or a heavy backend costs $150K to $300K+. Senior developers here charge $120 to $150 hourly.

• Scope creep kills budgets faster than complexity ever does.
• Flexible engagement exists beyond all-or-nothing six-month contracts available.
• MVPs launch in three months and cost half as much.

It takes 2 to 4 months for a simple MVP mobile app, completely. Design takes 2 to 5 weeks of focused work. Development takes 3 to 9 weeks, depending on the scope. Testing takes another two weeks. The App Store review adds one more week total. But you don’t have to build everything simultaneously.

• Simple apps take 2 to 4 months straightforwardly, always.
• Mid-range apps take 4 to 6 months of work.
• Complex apps take 6 to 9+ months minimum, always.
• MVPs launch quickly and collect real user feedback.

Yes, but they’re fundamentally not the same thing. iOS users spend more money per app consistently. Android reaches way more people globally, but testing is harder. Build a business? You probably want both platforms now.

• Cross-platform frameworks save weeks and cut costs dramatically.
• Some features demand native code for performance optimization.
• Start cross-platform, go native only if needed.

Old apps don’t stay working for very long. iOS and Android update every single year without fail. Your two-year-old app probably crashes on new devices. Sometimes a refresh works; sometimes rebuilding costs less long-term.

• Refresh updates design, fixes bugs, and maintains OS compatibility.
• Audit first shows which path makes financial sense.
• Rebuilding costs less than constant patches on code.

Launch is day one; it’s not the finish line. Real bugs only appear when real users hit production. Performance crashes under actual load, not test simulators. OS updates break things nobody anticipated at all. That’s when support matters most here, always.

• We monitor crash reports and performance metrics continuously.
• Bug fixes, security patches, and OS compatibility are included as a baseline.
• Budget fifteen to twenty percent of dev cost yearly.

Yes. All of it. Code ownership is non-negotiable and standard practice always. It’s yours to modify and hand off to others. We document it and organize it in your GitHub. Give you everything needed immediately for full control.

• Full ownership of code and IP from day one.
• Everything comes documented and organized for seamless handoff.
• Open-source libraries remain open for use everywhere.

Yes, we can integrate AI cleanly with professional AI integration services tailored to your business needs. Users expect smarter apps that learn from behavior. Chatbots, recommendations, and predictive features save real time always. It’s not ahead anymore; it’s how you stay competitive now. Integration adds two to four weeks of work.

• Healthcare apps use AI for diagnostic support always.
• Fintech uses it to detect fraud before it happens.
• Retail uses smart recommendations
• Travel uses personalization features.
• You need real data to train AI properly.
