How to Build an App (The Right Way)
A Step-by-Step Guide for First-Time Founders
So, you have an idea for an app… now what?
Should you hire developers? Raise money? Try to build it yourself?
Before you start writing code (or spending money), it’s important to understand the full app development process… and how skipping critical early steps can lead to costly mistakes.
At LunarLab, we help people turn early-stage ideas into successful, launch-ready products. We want your product to be as successful as possible. That’s why we’ve created this high level guide to help you build smarter, faster, and more cost-effectively from day one.
1. Start with a High-Level Idea (You are here 📍)
You’ve thought, “There should be an app for that…” and maybe even jotted down a few features. This is a great start… but you’re not ready to start development just yet. At this stage, your job is to stay curious and open-minded as you move into the next (critical) phase: discovery.
2. Discovery & Planning: Define the “Why” and “Who”
Before anything is designed or developed, great projects start with a strategic discovery phase. This is where you define your goals, success metrics, and what a “successful” app should look like. This phase includes:
- Defining what problem you’re solving
- Identifying your target audience and key user groups
- Outlining essential features (and which ones can wait)
- Analyzing competitors and market trends
- Validating your idea
- Planning your monetization or business model
Why it matters: Discovery reduces the risk of product failure by up to 75%. Skipping this step is like going on a road trip without a map or GPS. You need to know where you’re going and how to get there.
3. UX Design: Create the Blueprint Before You Build
Next comes User Experience (UX) Design. This phase is not about aesthetics (although the output can definitely look really great). UX Design focuses on how your app works and how users move through it, laying the foundation for functionality and flow.
This is where we transform your vision into wireframes or a clickable prototype that shows exactly how the app will work. It’s a lot like creating a blueprint for a building: you need to understand the architecture and how the whole thing will come together.
The design phase is also where clarity and cost savings come into play. Development teams work faster, cheaper, and with fewer errors when they’re handed a complete, validated design. Without one, they’re often forced to guess… leading to expensive changes later.
At LunarLab, we design with budget in mind. We’ll flag high-cost features and help you find smarter, lower-cost ways to deliver value to your users.
4. Estimate the Real Cost of Development
You may be tempted to get development quotes early in the process. But beware: any price you get before you have a completed design may be inaccurate or inflated to cover unknown risks.
Design uncovers risks and complexities, and gives a complete picture of exactly what needs to be built. This means that you’re significantly lowering the risk of encountering big unknowns that require you to pay more down the road.
Once your design is done, developers can give you a much more accurate estimate with far fewer surprises.
5. (Optional) Pitch with a Prototype
Many of our clients choose to pause after design and use the interactive prototype to raise funding or start attracting customer interest. This gives investors something tangible to react to, and shows that you’ve done your homework to reduce risk and clarify your vision.
Some of our customers have used great clickable prototypes to secure hundreds of thousands in funding, win pitch competitions, or even get enough customer sign-ups to fund the development phase.
Bonus: if you went through a really solid discovery phase, you’ll go into your pitch with a clear value proposition, defined target market, validated idea, realistic revenue model, and a bulletproof plan for success.
6. Development: Build the Real Thing
Once your design is complete, it’s time to bring in a development team to write code and bring your app to life. This step is often the most expensive, so vetting your development partner is absolutely essential.
Cheaper is not better: we’ve seen founders fall for rock-bottom prices that result in unusable, buggy apps (and expensive do-overs). A good design team (like LunarLab) can help you vet developers, avoid scams, and even connect you with trusted partners who match your budget and goals.
Pro tip: Even if you have the best development team in the world, the project can go sideways if you don’t have great communication. Clear communication is essential, but it’s also important to communicate in a way that aligns with how developers work. That means detailed documentation and limited surprises. The more ambiguity your dev team faces, the more likely your project will go off-track. That’s why great design and clear documentation are the best risk-reduction tools you can invest in.
We’ve compiled some great tips and tricks in our blog Developer Communication for Non-Technical Founders, but we also provide technical project management services to keep your project on time and on budget.
7. Testing: Make Sure It Works
As the app is being built, ongoing QA (quality assurance) is critical. This ensures your app actually does what it’s supposed to do… without bugs, crashes, or broken features. The development team should test each feature as it’s released.
But don’t just take their word for it: you should also test throughout the development process to ensure that everything is working as you expect it to work. You don’t want to get to the end of your project and find out that everything is broken!
Just before your final production release, you should always do UAT (User Acceptance Testing) to confirm that everything is ship shape. Your development team should have a warranty period or plan for fixing bugs during this stage so that you don’t launch with major errors.
This is also the time to do Beta Testing before your app goes live with a large audience. Beta testing is a big undertaking, but it’s also a great way to limit risk (and validate product market fit) before you bring in paying customers.
8. Launch & Maintain
Congratulations: you’ve made it! Once your app is tested and approved, it’s time to launch and enjoy the fruits of your labor. But the work doesn’t stop there. After launch, it’s important to monitor analytics, gather user feedback, and plan for future updates to continue improving the experience and increasing adoption. Plan for ongoing support, new feature additions, and maintenance to keep your app running smoothly and evolving with user needs. This will be a small cost each month.
TL;DR: Start with Design, Not Development
A common mistake we see is founders going straight to a development team before they’ve done the groundwork. This often leads to scope changes, budget overruns, and failed launches. It’s like trying to build a house before you know how big the kitchen needs to be or how many bedrooms you need to have.
A great design team sets the foundation for a successful build.
It helps you validate your idea, define the right features, and reduce development time and cost. And when you’re ready to build, we’ll help you choose the right development team so you don’t get burned.
