Books and Resources to Start Strong
Starting an app development business requires more than technical skill—you need to understand business fundamentals, user experience design, and how to validate your ideas before investing heavily in development. These books provide practical frameworks that apply directly to launching and growing your app business.
The Lean Startup by Eric Ries
This book teaches you how to build apps efficiently by testing your assumptions with real users before full development. You’ll learn to release minimum viable products (MVPs) quickly and iterate based on feedback rather than spending months building features nobody wants. For app developers, this approach saves thousands in wasted development hours.

Don’t Make Me Think by Steve Krug
User experience design directly impacts whether your app succeeds or fails. This book teaches usability principles in plain language—you’ll learn how to design interfaces users actually enjoy. Even if you’re not the designer, understanding these principles helps you work effectively with designers and avoid building unusable apps.

Traction by Gabriel Weinberg
Building a great app means nothing if nobody knows about it. This book breaks down 19 channels for getting users—from content marketing to partnerships to paid advertising. You’ll learn which channels work for different types of apps and how to prioritize your marketing efforts without wasting money.
The Pragmatic Programmer by David Thomas and Andrew Hunt
This classic covers professional development practices—how to write maintainable code, debug effectively, and collaborate with other developers. If you’re building apps solo initially or plan to hire developers, this book sets the standard for professional development habits that save time and prevent costly mistakes.

Equipment You Need
App development requires far less physical equipment than many businesses, but your computer and development tools are your entire operation. The key is choosing hardware that won’t slow you down during development and testing.
Computer Hardware
- Development laptop or desktop: The core of your business. You need a machine with sufficient RAM (16GB minimum, 32GB better) and processing power to run development environments, emulators, and multiple applications simultaneously. For iOS app development, a Mac is required; for Android or cross-platform work, Windows or Mac both work.
- External monitor: A second display dramatically improves productivity—you can view code on one screen and your running app on another. 27-inch 4K monitors are affordable and reduce eye strain during long coding sessions.
- Mechanical keyboard: You’ll type thousands of lines of code. A quality mechanical keyboard reduces hand fatigue and increases typing speed and accuracy over months of use.
- Mouse or trackpad: An ergonomic mouse prevents wrist strain during extended development sessions.

Testing Devices
- Smartphone for testing: You need a physical device matching your primary platform. If building for iOS, an iPhone or iPad. If targeting Android, a mid-range Android phone. Simulators and emulators work for initial testing, but real devices reveal performance issues and user experience problems.
- Tablet: Many apps run on tablets with different screen sizes and resolutions. Testing on both phone and tablet ensures your layouts work correctly across devices.

Software and Development Tools
- Integrated Development Environment (IDE): Xcode (free for Mac), Android Studio (free), or Visual Studio Community (free) are your primary tools. These include code editors, compilers, debuggers, and emulators.
- Version control system: Git (free) is essential for tracking code changes and backing up your work. GitHub (free tier available) or GitLab provide cloud storage and collaboration features.
- Design software: Figma (free tier available) or Adobe XD (part of Creative Cloud subscription) help you design interfaces before coding.
- API testing tools: Postman (free tier available) lets you test backend services and APIs your app will connect to.
- Project management: Trello (free tier) or Asana (free tier) help you organize tasks and track development progress.
Workspace Setup
- Desk: A standing or adjustable desk reduces back strain during 8-10 hour development days. You’ll spend more time sitting than in most jobs.
- Ergonomic chair: A quality office chair supports your back during long sessions and prevents chronic pain that derails productivity.
- Lighting: Bright desk lamp or task lighting prevents eye strain and headaches from poor lighting.
- Headphones: Noise-canceling headphones help you focus and maintain concentration during coding work.

Backup and Storage
- External hard drive or SSD: Backup your code and projects daily. A 1-2TB external drive costs $50-100 and prevents losing months of work to hardware failure.
- Cloud backup service: Backblaze or similar services provide automatic continuous backups, offering additional protection against data loss.

What to Buy First vs Later
Start lean and add equipment as your revenue grows. Your priority is a capable computer and testing devices—everything else is secondary.
- Month 1 (Essential): Development computer with at least 16GB RAM, one testing device matching your primary platform, external backup drive, and basic desk setup.
- Months 2-3 (High Priority): Second testing device to verify your app works across different phones, external monitor for improved productivity, mechanical keyboard and ergonomic mouse.
- Months 3-6 (Nice to Have): Ergonomic desk and chair upgrades as budget allows, tablet for testing tablet layouts, higher-end testing devices for premium device testing.
- Ongoing: Cloud services, subscriptions to premium development tools, and additional devices as you expand to new platforms.
New vs Used Equipment
For computers and development equipment, buying new gives you warranty protection and predictable performance—this matters because your computer is your business. A used laptop with unknown history might fail during critical development, costing you client deadlines and reputation damage. Budget $1,200-2,000 for a quality new development laptop.
Testing devices are where you can safely buy refurbished or used. Previous-generation iPhones and Android phones still reveal performance and design issues in your app. Refurbished devices from Amazon Renewed or manufacturer programs cost 30-50% less than new and work perfectly for testing. Avoid the absolute oldest models—you want devices from the last 3-4 years to test realistically. External monitors, keyboards, and chairs can safely be purchased used from local marketplaces without risk.
Where to Buy
- Amazon: Prime shipping on most items, easy returns, and verified seller reviews make this convenient for keyboards, monitors, external drives, and workspace equipment.
- B&H Photo: Specializes in computers and electronics with expert staff and detailed product information. Good for comparing development laptops and monitors.
- Best Buy: Quick in-store pickup available for urgent needs, knowledgeable staff for computer recommendations.
- Apple Store or manufacturer sites: Direct purchase of Mac computers includes warranty support and financing options for expensive equipment.
- Local electronics retailers: Support local businesses and try equipment in person before buying.
- Facebook Marketplace or local classifieds: Used office furniture, monitors, and older testing devices at significant discounts.
- Refurbished certification programs: Amazon Renewed, Apple Certified Refurbished, and manufacturer refurbished programs offer used devices with warranty protection.
