Who You Work with on Your App

Startup founders, product leads and engineering managers in San Francisco are the people we speak with most, usually with a busy roadmap and little spare time. Our contact stays brief and clear.

A Single Accountable Lead

Your project lead owns the schedule and picks up when you call. Mobile engineers, designers and QA testers stand behind that person, which gives a small team a larger bench.

Written Notes After Every Call

We talk on video, or face to face by arrangement. Afterward each one a short note lists decisions made, work completed and questions still open, so you never rely on memory.

Working Inside Your Process

We use your tickets, your repositories and your release rhythm where we can. Documentation is clear, and your own engineers can take over the code whenever you choose.

Apps We Build for San Francisco Industries

The city lists finance and real estate, information and technology, healthcare, hospitality and entertainment, and education among its major sectors, and UCSF anchors a strong life sciences cluster. Each shapes the app differently.

Technology and Software

How we help
Companion apps for SaaS products, onboarding flows and push messaging.
Plan for
Mobile releases that keep pace with your web app

Life Sciences and Biotech

How we help
Lab request, sample tracking and study coordination apps.
Plan for
Keeping datasets apart, with activity logs

Finance and Real Estate

How we help
Client portals, tenant requests and property inspection apps.
Plan for
Role-based access and tidy record keeping

Healthcare

How we help
Care coordination, scheduling and patient messaging apps.
Plan for
Sensitive information and accessible screens

Hospitality and Entertainment

How we help
Event guides, ticketing, table booking and guest service apps.
Plan for
Conference crowds and visitors on roaming data

Education

How we help
Student service, scheduling and course companion apps.
Plan for
Single sign-on and heavy enrollment weeks
Which privacy laws and sector rules apply to your product is for your legal team to decide. We build so they can review how the app collects and shares data.

iOS, Android or Both? A Plain-English Guide

Pick based on who uses the app, how fast you must ship and which device features matter. This is how we weigh the four routes.
Option

Native iOS

iOS app development
Pick it when
Your early adopters are on iPhones, or you rely on specific Apple features.
Watch for
Android users wait for a second build.
Option

Native Android

Android app development
Pick it when
Your audience skews Android, or the app needs close control of the device.
Watch for
iPhone users wait for a second build.
Option

Cross-Platform

Flutter and React Native
Pick it when
A small team wants one codebase for both stores and a shorter path to market.
Watch for
A few hardware features may still need native modules.
Option

Web App or PWA

Web application development
Pick it when
You’re testing demand and want no install step for early users.
Watch for
Limited device access and no app store presence.
Still deciding? Many startups begin cross-platform and move one performance-critical screen to native code later.

What We Check Before an App Goes to the Stores

Review delays cost a launch week. We go through this list before each submission.

What Shapes the Cost of an App

We don’t publish prices, because a mobile app can be a small utility or a full platform. Six things decide most of the effort.

Platforms

↑ Costs more when
iOS and Android each get a separate native build
↓ Costs less when
one cross-platform build serves both stores

Features

↑ Costs more when
payments, real-time sync and offline mode ship together
↓ Costs less when
version one covers a single core workflow

Design

↑ Costs more when
you want a bespoke motion language and design system
↓ Costs less when
standard components fit your brand

Integrations

↑ Costs more when
the app has to connect to multiple legacy or partner systems
↓ Costs less when
it talks to only a handful of well-documented services

Back End

↑ Costs more when
accounts, queues, dashboards and admin tools are built new
↓ Costs less when
your current services already expose what the app needs

Compliance

↑ Costs more when
it holds health or financial data and faces audits
↓ Costs less when
the data is low-risk and easy to separate

Hire Mobile App Developers

Choose by stage. A funded founder with a defined first release may want a fixed build, a team still testing ideas often prefers time and material, and a company short of mobile engineers suits dedicated developers.

Fixed Price Build

Scope, milestones and price are settled upfront. Fits a clear brief and a target launch.
Suits

Time and Material

Hours worked are billed and you reset priorities at every sprint. Fits products that evolve with user feedback.
Suits

Dedicated Developers

Mobile engineers, QA and a designer join your sprints and tools. Fits long roadmaps.

How to Choose an App Development Company

Most proposals promise the same things. These seven questions show how a team works when the pressure is on.
01

Who Are the Engineers Writing My App?

Listen for
Named engineers and their roles, not a general pledge.
02

When Do I Get Something to Try?

Listen for
A build you can install when each sprint ends.
03

Who Holds the Repositories and Developer Accounts?

Listen for
You do, and the contract spells it out.
04

What If an Earlier Team Left the App Half Built?

Listen for
A review of code and design first, then a written plan to recover.
05

What Happens After the App Is Live?

Listen for
Crash monitoring, fixes and an update plan agreed in advance.
06

Can You Join Our Sprints and Tools?

Listen for
Yes, with shared boards, pull requests and agreed hand-offs.
07

Would You Be Upfront If a Web App Is Enough?

Listen for
Yes, after a fair look at a web app against a native build.

How We Run an App Project

Work happens in six stages, each wrapping up with a deliverable for you to review. Duration depends on app size.
01

Discovery

About a week of workshops to map users, goals and technical limits.
02

Scoping and UX

Typically one to two weeks to turn findings into a scope, user flows and a written quote.
03

Design and Prototype

Around two weeks for a clickable prototype you can put in front of users.
04

Sprint Builds

We work in brief sprints that each close with an installable build.
05

Testing and Store Readiness

Allow around four weeks for device coverage, speed work and store compliance.
06

Launch and Iterate

We ship, track crashes and usage, and plan what comes after.
Each stage ends with something you can review.

The Villas Mooloolaba

Hospitality / Boutique Vacation Rental
The Villas Mooloolaba does the hard part well – four unique two-bedroom villas around a shared pool on Queensland’s Sunshine Coast. The website wasn’t carrying its weight: competing against hotel chains and OTA listings meant direct booking had to feel just as easy, and guests couldn’t easily compare all four villas.
