You can build an app without coding experience, but the path depends on what your app needs to do
Building an app starts with deciding whether you want to code it yourself, use a no-code platform, or hire someone else. If you have no programming background, no-code tools like Flutterflow, Bubble, or MIT App Inventor let you build real, working apps by dragging components onto a screen instead of writing code. If you want to learn to code, you'll start with a language like Swift (for iPhone), Kotlin (for Android), or JavaScript (for both), which means months of learning before you have something functional. If you want to skip both, you can hire a developer — but that costs money upfront and you need to know what you're asking for.
The choice matters because it affects how much time you spend, what your app can do, and whether you can change it later. A no-code app built in Bubble can go live in weeks. A custom-coded app takes longer but gives you more control. Learning to code takes the longest but teaches you skills that carry to other projects.
Key Takeaways
- No-code platforms like Flutterflow, Bubble, and MIT App Inventor let you build working apps without writing code, usually in weeks rather than months.
- If you want to learn coding, start with Swift for iPhone apps, Kotlin for Android apps, or JavaScript for apps that work on both, using free resources like freeCodeCamp or Codecademy.
- Your app needs a backend (a server that stores data and handles logic) unless it's very simple — no-code platforms usually include this, but custom-coded apps require you to set it up separately.
- Testing on real phones before launch catches problems that don't show up in simulators, and both app stores (Apple's App Store and Google Play) review apps before they go live, which takes one to three days.
- Start with the smallest version that solves one real problem, not a feature-packed app — you can add features later once people are actually using it.
No-code platforms: build without writing code
No-code app builders let you design and launch an app by clicking and dragging, without touching code. Flutterflow is built on top of Google's Flutter framework and exports real code, so your app runs as fast as a hand-coded one. Bubble is better for apps that need complex data and user accounts — it handles the backend for you. MIT App Inventor is free and designed for learning; it's simpler than the others but limited to Android. Adalo and Thunkable are middle-ground options that work for both iPhone and Android.
The trade-off is flexibility. No-code platforms are fast and cheap, but they can't do everything a custom-coded app can. If your app is a to-do list, a simple marketplace, a booking system, or a social feed, a no-code platform will work. If your app needs custom animations, real-time multiplayer features, or deep integration with phone hardware (like the camera in a specific way), you'll hit the platform's limits.
Most no-code platforms charge a monthly fee to keep your app running — usually $20 to $100 per month depending on how many users you have. Some let you export your code and host it yourself, which costs less but requires more technical knowledge.
Learning to code: the longer path with more control
If you want to code your own app, you need to pick a language and a starting point. Swift is Apple's language for iPhone and iPad apps. Kotlin is Google's language for Android apps. JavaScript with a framework like React Native or Flutter (via Dart) lets you write one codebase that works on both iPhone and Android.
Start with free resources: freeCodeCamp on YouTube has full courses in Swift, Kotlin, and JavaScript. Codecademy offers interactive coding lessons. Apple's Swift Playgrounds app teaches Swift on an iPad. Google's Android Basics in Kotlin course is free and official. Expect three to six months of consistent practice before you can build something real, and longer if you're learning part-time.
Once you know the language, you'll need to learn how to build the user interface (what the app looks like), handle data storage, and connect to a backend server. Xcode (Apple's free tool) is where you build iPhone apps. Android Studio (Google's free tool) is where you build Android apps. Both are large programs with steep learning curves, but they're the standard tools professionals use.
Hiring a developer: when to outsource
If you have a clear idea, money to spend, and no interest in learning to code, hiring a developer is faster than doing it yourself. Developers on platforms like Upwork, Toptal, or Fiverr charge anywhere from $20 to $150 per hour depending on experience and location. A simple app might cost $5,000 to $15,000. A more complex one could cost $30,000 or more.
Before you hire, write down exactly what your app does, what screens it has, and what data it needs to store. The clearer you are, the more accurate the quote. Ask developers for examples of apps they've built, and check whether they've shipped apps to the App Store or Google Play before — that matters because publishing has its own rules and gotchas.
One risk: if you hire someone and they disappear, you may not have the code or the ability to change it. Ask for the source code in writing as part of the contract, and consider hiring someone who will teach you how to maintain it or hand it off to another developer later.
Your app needs a backend unless it's very simple
A backend is a server that stores your users' data, handles login, and runs logic that the phone can't run alone. If your app is just a calculator or a flashcard deck with no user accounts, you don't need one. If your app has user accounts, lets people message each other, stores photos, or syncs data across devices, you need a backend.
No-code platforms like Bubble and Flutterflow include a backend, so you don't have to set one up yourself. If you're coding, you have options: Firebase (Google's backend service) is free up to a point and handles user login, data storage, and hosting. Supabase is an open-source alternative. AWS and Azure are more powerful but harder to set up. Most beginners start with Firebase because it's the simplest.
Backend costs vary. Firebase is free for small apps and charges based on how much data you store and how many requests you make. A small app with a few hundred users might cost nothing. A popular app could cost $100 to $1,000 per month. Plan for this before you launch.
Testing on real phones before you submit to app stores
Simulators (fake phones on your computer) are useful for quick testing, but they don't catch everything. Test on a real iPhone and a real Android phone if you can, because the simulator doesn't show how your app performs on slower hardware or with a real internet connection.
Both Apple and Google require you to submit your app for review before it goes live. Apple's App Store review takes one to three days and checks whether your app follows Apple's rules — no scams, no hidden charges, no apps that are just wrappers around a website. Google Play review is usually faster, one to two days, and less strict. Both can reject your app, so read their guidelines before you submit.
Before you submit, test these things yourself: Can you create an account and log in? Can you do the main thing your app is supposed to do? Does it crash if you close it and reopen it? Does it work on a slow internet connection? Does it handle the case where the user has no internet at all? These are the things reviewers check.
Start small: build the minimum version first
The biggest mistake new app makers make is trying to build everything at once. You imagine a feature-packed app with ten screens, user profiles, messaging, payments, and notifications. Then you spend six months building it, launch it, and nobody uses it because you built the wrong thing.
Instead, build the minimum viable product — the smallest version that solves one real problem for one type of user. If you're building a habit tracker, don't add social features, streaks, and analytics on day one. Build the ability to add a habit, check it off each day, and see a list of your habits. Launch that. Get people using it. Then ask them what they want next.
This approach saves time and teaches you what actually matters. You'll learn more from ten real users using a simple app than from six months of building alone. And if your idea doesn't work, you've only spent weeks, not months.
Frequently Asked Questions
Do I need to know how to code to build an app?
No. No-code platforms like Flutterflow and Bubble let you build real, working apps without writing any code. You design the app by dragging components onto a screen, the same way you'd design a website in Figma. You'll still need to understand how data flows and what your app should do, but you don't need to write code.
How much does it cost to build an app?
It depends on your path. No-code platforms charge $20 to $100 per month to keep your app running. Learning to code is free (courses and tools are free), but takes months of your time. Hiring a developer costs $5,000 to $50,000 depending on complexity. Most people underestimate the time cost of learning or building yourself.
Can I build an app that works on both iPhone and Android?
Yes. No-code platforms like Flutterflow and Adalo export apps for both. If you're coding, use React Native or Flutter (with Dart), which let you write once and deploy to both. The alternative is to code separately for each platform — Swift for iPhone, Kotlin for Android — which takes longer but gives you more control.
How long does it take to get an app on the App Store?
Apple's review process takes one to three days. Google Play is usually one to two days. Before that, you need to build the app (weeks to months depending on complexity) and test it. The review itself is fast; the building is what takes time.
What if I build an app and nobody uses it?
That's normal. Most apps don't get users because the maker built something nobody wanted, not because the app was broken. This is why starting small matters — if you spend two weeks building a simple version and it doesn't work, you've learned something valuable without wasting months. Then you can try a different idea.
