Before You Build: The Two Things to Get Right Before You Hire a Mobile Developer

This is the first post in a series adapted from my guide, Build It Right: An Insider's Guide to Mobile App Development for Non-Developers. Each entry takes one slice of the guide and turns it into something you can read in ten minutes.

If you're planning to build a mobile app and you're not a developer yourself, the freelance market you're about to enter is one of the most confusing markets a non-technical buyer can walk into. There are talented people everywhere. There's also rushed work, overpromised timelines, code you can't maintain, and apps that look finished but can't actually ship. Most clients don't learn the difference until after they've paid for it.

This series is meant to change that. Over the next several posts I'll walk through what I wish every client knew before they hired their first developer — what good projects do at the start that bad ones don't, where the freelance market quietly takes advantage of non-technical buyers, and how to spot trouble before it's expensive.

We're starting with the part that happens before you've posted a job: the work you should be doing yourself, before any developer is involved.

Two things matter most at this stage: knowing what you're actually building, and understanding what the project really involves. Most clients underestimate both, and pay for it later.

1. Know — and articulate — your vision

Your developer doesn't share your understanding of the problem your app is solving, or what makes it distinctive. They can't. You've spent months or years thinking about this; they're hearing about it for the first time. Misunderstandings about the product cost time, money, and goodwill on both sides, and they're nearly always preventable.

Knowing what you want isn't enough on its own. You have to describe it in meticulous detail, both verbally and in writing. A simple storyboard with images or rough sketches illustrating the user experience helps enormously. You don't need to understand the underlying technologies, but you do need to be able to explain what the app does, why it exists, and how a user interacts with it. If you can't, you're not ready to hire a developer.

A tip: use AI to clarify your own thinking

Modern AI tools are very good at helping a non-technical person turn a vague idea into something describable. You can talk through your idea in conversation with an AI, have it draft feature descriptions, produce written walkthroughs of user flows, and generate rough visuals of screens from a prose description. None of this replaces the work of real design once development begins, but it can take a fuzzy idea in your head and turn it into something a developer can actually respond to.

If you've been struggling to put your idea into words, this is a low-cost, high-value place to start.

Unclear scope is one of the most common reasons projects blow past their timelines and budgets. Time spent clarifying the vision before development starts saves far more time than it costs.

2. Understand what it actually takes

Building an app well involves more than writing code. A developer handles the code, but several other disciplines determine whether the end product actually works. If you walk in thinking "developer equals app," you're going to miss most of what's about to happen.

Here's what's actually involved.

Project management

Keeping the project on schedule and within budget. Detailed work breakdown structures are overkill for most freelance projects, but a single "due date" with nothing in between is a recipe for failure. What works is an iterative approach with small, specific milestones, consistent check-ins, and someone — your project manager or the freelancer themselves — who knows when to constructively challenge a status update. If nobody is paying attention between milestones, problems compound invisibly until the next check-in, and the next check-in isn't where you want to be discovering problems.

UI/UX design

How your app looks and how users interact with it. For consumer-facing apps, strong aesthetics and usability aren't optional. With millions of apps on the store, users abandon anything that's ugly or confusing within seconds.

UI/UX design is a specialized craft. It draws on artistic skill and on a deep understanding of the target platform and how it shapes user expectations. Don't expect your developer to be a designer; their strength is programming. Budgeting for a designer who produces detailed screen mockups — color, typography, spacing, graphical assets — is one of the more consequential investments you'll make in the project.

Testing

Quality assurance to confirm the app works as designed and holds up under real use. This goes beyond catching bugs; it covers performance, resiliency, and behavior across a range of devices and conditions.

Your developer should test their own work, and you should verify what you receive, but for most apps that isn't enough. Specialized testers find issues the developer won't spot, and they verify that the app works across the range of real-world devices your users actually carry. Consider hiring a tester to review and document testing steps, ideally well before final delivery rather than at the end. Buggy behavior gives users an easy reason to delete your app and move on. The store is full of alternatives.

Communications

The single biggest factor in whether a project succeeds. Communication problems are especially common in freelance engagements, where you're relying on individuals who may not have been trained in it.

When you're evaluating a freelancer, vet their communication carefully:

• Can they explain things without jargon or condescension?

• Do they ask sharp, probing questions and build real rapport?

• Are they candid when the news isn't positive?

• Do they actually listen to what you're saying and respond with substance?

• Are they willing to engage with your budget and offer options?

"The sales phase is when a freelancer's incentive to communicate well is at its peak. If they're not putting that effort in while they're trying to close the deal, they're not going to start once the contract is secured."

If communication is poor during the interview, it will almost certainly be worse once the contract is signed. Treat any communication concerns at the interview stage as load-bearing.

Budget understanding

A freelancer doesn't just charge you for their time. A good one manages your investment. That includes advising on technology choices, growth planning, maintenance, and other costs you may not have thought of. The true cost of a project extends well beyond the developer's fees: backend infrastructure, developer-account fees for the Apple and Google stores, revenue shares on any paid apps or in-app purchases, design work, testing, scaling costs, ongoing maintenance — all of it adds up.

A freelancer who treats your investment as their own will keep you informed of costs you may not have seen coming. A freelancer who only wants to talk about their own hours is not managing your budget, regardless of whether they use those words.

Monetization strategy

If your app is meant to generate revenue directly, you need a developer who understands the available models — subscriptions, in-app purchases, advertising, paid downloads — and can discuss which ones fit your business goals. This isn't a detail to figure out at the end. Monetization design decisions shape the whole app, and getting them wrong can get you rejected at App Store review.

Selecting complementary technologies

Most apps depend on external services: databases, authentication, analytics, push notifications, payments, social integrations, APIs. A strong developer knows the trade-offs between the major options — integration cost, ongoing maintenance cost, vendor lock-in, long-term viability — and can recommend what fits your project. Getting this right at the start avoids painful and expensive migrations later. Getting it wrong means rebuilding infrastructure mid-project, usually at the worst possible moment.

The point

If you scan back over the list above, you'll notice something: not all of these are technical. Communication, budget management, monetization strategy — those are business judgment problems. The developer you hire is going to make decisions in every one of these areas, whether or not they're equipped to. Whether they're equipped to is one of the things you're actually evaluating when you hire them.

The clearer you are about what you're building, and the more honestly you've thought about everything the project involves, the better positioned you are to recognize a freelancer who can steward all of it — and to spot one who can only handle a slice.

The next post in the series gets into how to actually do that recognition, starting with how to read a freelancer's profile and what to listen for when you're talking to one.
