Big thanks to the Toimi team! Everything was done thoughtfully, tastefully, and right on schedule. Loved how design and development were handled together — quick approvals, quick launch. Super easy to work with.
We came in with a task tailored to our business — and everything was adapted to fit, no templates. What we appreciated most is that they didn’t just think about how to build it, but why. You can feel the care in their approach.
We ordered a webinar interface design and a couple of fintech-related things from Toimi — everything was on point. What stood out was that they didn’t just deliver, but also suggested ways to simplify. We took notes.
We plan to continue working
with Toimi!

Mobile app projects in San Francisco typically range from $25,000 to $150,000 depending on complexity, platform choice, and feature set. A basic iOS or Android app with standard functionality starts around $25,000 — $35,000, while more sophisticated applications with real-time data, payment integration, or custom backend systems can exceed $100,000. San Francisco's competitive tech market means you're investing in developers who understand the expectations of users in SoMa, Financial District, and beyond. We provide transparent quotes after understanding your specific requirements and business goals.
Most mobile app projects in San Francisco take 3 to 6 months from initial concept to App Store or Google Play launch. Discovery and design typically require 3-4 weeks, development spans 8-16 weeks depending on features, and testing plus deployment add another 2-3 weeks. San Francisco clients often need faster timelines to meet fundraising milestones or market opportunities — we can accelerate delivery with focused sprints when needed. Complex apps with advanced integrations or enterprise requirements may extend to 9 months. We establish clear milestones at project start so you know exactly when to expect deliverables.
We develop mobile applications for fintech companies in the Financial District, healthcare startups near UCSF Mission Bay, logistics platforms serving the Port of San Francisco, and consumer apps targeting the Bay Area market. San Francisco's concentration of venture-backed startups means we frequently work with early-stage companies building their first mobile product, as well as established businesses in Presidio and SOMA upgrading legacy systems. Whether you're in biotech, retail, transportation, or B2B SaaS, we adapt our development process to your industry's compliance requirements and user expectations.
We develop both native applications using Swift for iOS and Kotlin for Android, as well as cross-platform solutions with React Native or Flutter depending on your requirements. Native development delivers the best performance and access to platform-specific features — ideal for apps needing advanced camera functionality, complex animations, or tight hardware integration. Cross-platform approaches reduce development time and cost when you need simultaneous iOS and Android presence with shared business logic. Many San Francisco clients prioritize native iOS first given the Bay Area's high iPhone adoption, then expand to Android based on user data. We recommend the approach that best matches your timeline, budget, and technical needs.
Our process covers discovery workshops, UX/UI design, native or cross-platform development, API integration, quality assurance testing, and App Store submission. We start by understanding your users and business model, then create interactive prototypes you can test with actual customers before writing production code. Development follows agile sprints with bi-weekly demos so you see progress continuously. We handle backend infrastructure when needed, integrate third-party services like payment processors or analytics platforms, and ensure your app meets Apple and Google's submission guidelines. Post-launch, we monitor performance metrics and can provide ongoing maintenance or feature additions as your San Francisco user base grows.
We implement automated testing, manual QA across multiple device types, performance profiling, and security audits throughout development. Every feature goes through unit tests and integration tests before reaching your staging environment. San Francisco users expect apps that load instantly and respond smoothly — we optimize render performance, minimize API latency, and test on both new iPhone models and older devices still common in the market. Before App Store submission, we conduct accessibility reviews, battery consumption analysis, and network performance testing on cellular connections. Our QA process catches issues early so you launch with confidence rather than scrambling to fix bugs after release.
You'll have a dedicated project manager as your primary contact, plus direct access to the lead developer and designer working on your application. We schedule weekly video calls to review progress, discuss upcoming features, and address questions — more frequently during critical phases if needed. Between meetings, we communicate via Slack or your preferred platform for quick updates and decisions. San Francisco clients appreciate our transparency around blockers or timeline changes rather than discovering issues at the last minute. You'll receive access to our project management tool where you can track every task, view designs, and test development builds on your own devices throughout the process.
Post-launch support includes monitoring for crashes or performance issues, releasing bug fixes, updating for new iOS and Android versions, and maintaining compatibility with backend APIs. We offer monthly maintenance plans starting at $2,000 that cover routine updates, security patches, and minor adjustments based on user feedback. Many San Francisco clients choose ongoing development relationships where we add features quarterly based on analytics and user requests. When Apple or Google release major OS updates each fall, we ensure your app remains compatible and takes advantage of new capabilities. We're available to scale your team as your user base grows and feature requirements expand beyond the initial launch version.
