To build and launch a mobile app from scratch, you define the problem, identify your users, validate demand, pick the first-version features, choose a build route, prototype, build, test on real iOS and Android devices, submit to the stores, then promote and keep improving. That is roughly ten steps, and most of them happen before or after the coding1. Expect to spend real effort on promotion too: one development firm notes that you typically need more time to promote an app than to develop it2.
The sections below walk through each step, the build options and their tradeoffs, how cost is set, how apps earn money, and how hard the whole thing is for a non-coder.
The essential steps, in order
MobiLoud, which says it has helped publish more than 2,000 apps since 2013, lays out a path most projects follow1:
- Define the problem your app will solve.
- Identify the people who will use it.
- Validate that there is real demand.
- Decide which features belong in the first version.
- Choose how you will build the app.
- Map the user journey and create a prototype.
- Build or configure the app.
- Test it on real iOS and Android devices.
- Prepare app-store listings and submit.
- Launch, promote and keep improving.
The order is not rigid. Testing may send you back to design, and early feedback may change which features make the cut1.
Define the idea and the reason for it
Koombea suggests three questions to pin down the idea: why you want the app, what purpose it serves, and how that purpose fits your wider goals3. A vague idea wastes budget, because you cannot prioritize work you have not defined.
KeyToTech frames useful apps around a few jobs: saving time, reducing effort, adding accessibility or connecting people. An app that solves more than one problem has an easier path, it argues2.
Know your audience before you build
If you struggle to say how the app benefits users, they will struggle to see it too, and apps with no clear value are quickly abandoned3. KeyToTech recommends looking at the profession, age, employment and position of target users, finding the themes that link them, and gathering early feedback to decide what the app should do2.
The competition for attention is real. KeyToTech cites RescueTime data showing people spend about 3 hours 15 minutes a day on their phones, with 90% of mobile time in apps. Users open around 9 apps a day and 30 a month, while the App Store holds about 2.2 million apps and Google Play about 2.8 million2.
Study competitors in the stores
Cleveroad recommends browsing similar apps on the App Store and Google Play and noting six things: features, monetization or price, publisher type, last update date, download numbers, and ratings and reviews4. The App Store does not show downloads, so it suggests a tool such as SensorTower.
Reviews show what current apps are missing. Sort each competitor's features into three groups: core, unique and missing. In Cleveroad's video-on-demand example, core features were registration, profile, video player and search. Movie rental cards were unique, and comments and parental control were missing4. The missing column is where your opening often sits.
Scope a minimum viable product
An MVP is a pared-down version with only the essential features. Startups use it to validate the idea before spending on extras3. Cleveroad splits features into core and additional. For a music app like Spotify, the core list is sign-up and profile, a homepage of popular tracks, favorites, search and a player. Downloads, social sharing, personal mixes, similar artists and track recognition come later4.
Design, test and submit
Design is a competitive weapon on its own. KeyToTech notes that when several apps do the same thing, a user-friendly design can be enough to win, and that well-planned registration and onboarding improve retention and downloads2. Before submitting, test on real devices, not only simulators1. Koombea also lists security and maintenance as a core task, not an afterthought3.
Choosing how to build: code, no-code, hire or convert a website
Your build route affects cost, timeline, flexibility and how much technical work lands on you. MobiLoud compares four options1:
| Route | Best for | Coding from you | Relative cost | Speed |
|---|---|---|---|---|
| Code it yourself | Developers, learners, highly custom products | High | Low cash, high time | Slow |
| No-code or AI-assisted builder | Prototypes, fairly standard apps | Low | Low to moderate | Fast |
| Freelancer, agency or in-house team | Custom apps without in-house skills | None | High | Moderate to slow |
| Build from an existing website | Businesses with an online property, such as ecommerce | Low | Low to moderate | Fast |
Coding it yourself
Native iOS usually means Swift and Xcode. Native Android commonly uses Kotlin and Android Studio. Flutter or React Native lets you write much of the app once for both platforms1. This gives the most control. The catch is the scope of a production app: front ends for both platforms, a backend and database, login, payments, API integrations, security and privacy controls, analytics and crash reporting, deployment systems and ongoing compatibility updates.
No-code and AI-assisted builders
These suit simple customer apps, internal tools, directories, booking apps, community and content apps, and MVPs1. Before you commit, check whether the tool publishes to both stores, whether you can export code or data, how it handles accounts and payments, what happens if you outgrow it, who handles store submission and updates, and what the full production plan costs. AI can speed up the first version, but you still need to review generated code, test and protect user data.
An Entrepreneur contributor adds a limit: builders help extend an online presence to mobile but do little for a custom app with unique functionality5.
Hiring a team
Cleveroad, itself an agency, argues that a qualified team takes responsibility for the result in a way builders do not4. Treat that as the view of a vendor that sells development. KeyToTech notes that good firms often offer a free consultation under a non-disclosure agreement, which lets you share the concept and get a cost estimate2.
How much it costs to build an app
None of the retained sources gives a single price, and you should be wary of anyone who does without seeing your feature list. What they agree on is what drives the number.
KeyToTech says cost depends mainly on the number of features, the functionality and the compatibility requirements in the project scope2. Koombea stresses that development is not cheap, and that a clearly defined purpose is the main way to control spending. Without it, resources get misused and the bill grows3.
Your build route sets the scale. In MobiLoud's comparison, coding it yourself has a low cash cost but a high time cost. No-code tools and website-based builds sit at low to moderate cost. Hiring a freelancer, agency or team is the high-cost option1. With builders, MobiLoud warns, look at the full production plan rather than the entry-level price.
A written feature list is what makes an estimate possible. Cleveroad says a development company cannot estimate hours, and so cost, without one, and shows estimates broken down by hours per feature4. Doing research before you contact developers matters too: paying an agency to research from scratch spends money you could put into features, design or marketing.
Budget for what comes after launch. Maintenance, security and updates continue for the life of the app3, and someone must keep up when Apple or Google changes its requirements1.
How apps make money, and which model earns most
Decide on monetization during research, not after launch, because it shapes features and design. Cleveroad lists four models with examples4:
- In-app advertising: brands pay for space in your app (Kayak, Airbnb).
- Freemium: free to download, pay to add features or content, remove ads or make purchases (MX Player Pro, LastPass Premium).
- Premium: users pay before downloading (Facetune, Skyview).
- Subscription: free, with an optional subscription (Deezer, Netflix, Spotify, NY Times).
KeyToTech adds single purchases, bonuses, affiliate links and donations, and recommends analyzing what competitors charge before choosing2. Not every app needs to profit directly. Enterprise tools, for example, deliver value in other ways.
Tradeoffs of each model
The Entrepreneur contributor names four models that work best, each with a catch5:
- Pay once, full access. Users expect free updates, so repeat revenue is very hard.
- Pay once, then pay for extras. It adds revenue but draws criticism, because buyers expect everything included.
- Freemium. Popular in games; the free version offers basic features while paid purchases grant access to extra content.
- Free with ads. Works when you expect many downloads and long sessions.
Is there a single top money-making app?
The sources do not name one, and a ranking would not help you choose a model. What they show is that the earning model has to match the product. Streaming and news apps such as Netflix, Spotify and the NY Times app run on subscriptions, while travel platforms such as Kayak and Airbnb are cited for advertising4. Ads suit high-download, long-session apps, and freemium suits games5. Pick the model that fits how often and how long your users will open the app.
Cleveroad suggests filling in Alex Osterwalder's Business Model Canvas to record your audience, value, channels and revenue streams in one place4.
Is it hard to create an app?
The coding is hard; the project is manageable if you split the work. Koombea says mastering the full technical process takes hands-on experience and specialized training that can take years3. But you do not have to be the programmer.
Andreas Kambanis, founder of Nibble Apps, told Entrepreneur he never had programming skills and it never held him back: if you add value through marketing or content, the coding can be outsourced5. The same article warns that outsourcing is not hands-off. You will field many messages and spec out so many details that it can feel like coding it yourself. You also tend to get what you pay for.
The less visible difficulty is design. KeyToTech notes that small, nuanced design decisions take considerable time, and that design never really ends. It keeps iterating on reviews and feedback2.
To lower the difficulty:
- Keep the first version to the few features that deliver core value1.
- Use a no-code tool for a prototype if the app is fairly standard.
- Validate demand before spending significant money.
- Write the feature list yourself before talking to developers4.
Launching and promoting the app
A good app does not sell itself. When the Entrepreneur piece was written, the stores already held more than 1 million apps, and the author stresses that building a great one is not enough5. Plan promotion from the start1.
Practical launch tactics
The sources describe several types of mobile marketing you can combine5:
- Early adopters. Release early with core features and let people test before you flesh out the rest. This builds a user base for launch day and validates the idea.
- Differentiation. Offer unique features, serve a specific niche, or both.
- Exclusivity. Spotify launched in the US by invitation only, which helped it scale and built hype.
- App store optimization. Put the right keywords in your title and description, much like search engine optimization.
- Social sharing. Let users share results, such as a game score or weight lost, so they spread the word.
Koombea also lists app store optimization among the core tasks of building an app3. After launch, keep improving based on reviews and feedback, and keep the app updated for new platform requirements1.
Reaching people through search
Store search is only one channel. Many people look for solutions on Google before they ever open a store, so blog content that answers those searches can send readers to your download page. Ollie is an SEO engine for app founders that writes blog posts from Google search data, lets you approve each article before publication and counts the downloads each post generates. Ollie offers a free tier of 4 articles and a free blog address, with the option to connect a custom domain. Content like this supports your marketing strategy rather than replacing it, and no tool can promise a set number of downloads.
