You might think building an app is just about hiring a developer and waiting a few weeks. But here’s the truth: developing a fully functional app can take anywhere from 2 to 12+ months, depending on a range of factors—some that even seasoned founders overlook.
Take Instagram, for example. The first version of the app took just 8 weeks to build—but that was only possible due to laser-focused features and a highly experienced team. Most apps, especially those that require user accounts, back-end infrastructure, or third-party integrations, take much longer.
If you’re considering developing an app—whether it’s the next big social network or a simple tool for your business—understanding the timeline will help you plan your budget, launch, and marketing strategy with far fewer surprises.
Quick Answer: How Long Does It Take to Develop an App?
-
On average: Developing an app takes 4 to 9 months.
-
Fastest time possible: A basic MVP (minimum viable product) can be built in 2 to 3 months.
-
Longest possible time: Complex, multi-platform apps can take 12 to 18+ months.
What Affects the Time It Takes?
1. App Complexity: What Does the App Actually Do?
The more features, the longer the timeline. A simple app with one core function (like a calculator or note-taker) will be quicker to develop than an app with user logins, payments, push notifications, or geolocation features.
Speed Tip: Start with an MVP—just the must-have features—and build out later.
2. Design Requirements: Looks Matter
Custom UI/UX design can take several weeks. If you're using templates or design kits, you'll save time. But if your app needs animations, unique branding, or a pixel-perfect UI, expect delays.
Speed Tip: Use a design system like Google’s Material Design or Apple’s Human Interface Guidelines to cut down back-and-forth time.
3. Development Team Structure
Hiring an experienced agency, freelance developers, or building in-house each affects the pace. Agencies usually move faster but cost more, while freelancers and in-house teams might need more coordination.
Speed Tip: Choose a team with proven experience in your app type—e.g., ecommerce, healthcare, social media.
4. Platform Choice: iOS, Android, or Both?
Building for both iOS and Android natively takes nearly double the effort compared to one platform. Using cross-platform frameworks like Flutter or React Native can speed things up.
Speed Tip: Start with one platform if your budget or time is tight—usually iOS, since it’s quicker to launch on the App Store.
5. Backend Infrastructure
Apps that require user accounts, databases, or APIs need solid backend support. Building this from scratch takes time. Using tools like Firebase or AWS Amplify can speed things up.
Speed Tip: Use backend-as-a-service (BaaS) platforms to avoid reinventing the wheel.
Best-Case vs. Worst-Case Scenarios
If you’ve got a clear idea, limited features, and an experienced dev team, you could launch a basic app in just 2-3 months. Think of a to-do list or habit tracker.
But if you’re aiming to build a feature-rich app like Uber, with real-time GPS tracking, user profiles, payments, and a robust backend, expect a timeline of 12 to 18 months, especially with ongoing testing and iterations.
Common Mistakes That Slow the Process (Avoid These!)
-
Mistake #1: Overloading the MVP
-
Trying to build everything at once delays launch.
-
Fix: Focus on 1-3 core features for the first version.
-
-
Mistake #2: Vague Requirements
-
Developers waste time guessing or redoing work.
-
Fix: Create wireframes or user stories before development begins.
-
-
Mistake #3: Changing Scope Midway
-
Adds weeks or months to the project.
-
Fix: Finalize your app’s core features before writing any code.
-
-
Mistake #4: Ignoring Testing
-
Bugs discovered late can derail launches.
-
Fix: Allocate time for QA testing in every phase.
-
-
Mistake #5: DIY Project Management
-
Poor coordination can slow everything down.
-
Fix: Use project management tools like Jira or Trello and assign a dedicated product owner.

FAQs: Related “People Also Ask” Questions
How can I speed up app development?
Start with a clear feature list, use a cross-platform framework, and launch an MVP first. Hiring a team that’s built similar apps before also cuts development time significantly.
What’s the fastest way to build an app?
The quickest route is using no-code or low-code platforms like Glide or Bubble for simple apps. For native apps, React Native is a great cross-platform option.
How long does it take to develop an MVP app?
An MVP app usually takes 2 to 4 months, depending on features and team experience.
Can one person build an app?
Yes, a solo developer can build an app, especially if it’s simple. But expect longer timelines—usually 6 to 12 months, depending on their experience and time commitment.
Is app development faster with AI tools?
AI tools like GitHub Copilot can speed up coding tasks, but planning, design, and testing still require human input. At best, AI shaves off 10-20% of development time.
How long does it take to design an app UI/UX?
Designing the UI/UX of an app can take 2 to 6 weeks, depending on the number of screens and design complexity. Apps with animations or custom interactions typically take longer.
How long does it take to build a simple app?
A simple app with 1-2 core features can be built in 2 to 3 months if the requirements are clear and the development process is streamlined.
How long does it take to launch an app on the App Store or Google Play?
Once development is complete, launching an app typically takes a few days to 1 week. iOS apps require approval from Apple, which can add a few days to the process, while Android apps are usually live within hours.
How long does app testing take?
Testing usually takes 2 to 4 weeks, depending on the app’s complexity and the number of devices/platforms it supports. This includes QA, bug fixing, and user acceptance testing.
How long does it take to make a cross-platform app?
A cross-platform app built with frameworks like Flutter or React Native can take 3 to 6 months, which is faster than building separate native apps.
Can I build an app in a month?
It’s possible to build a basic MVP in 4 to 6 weeks, but this requires a small feature set, clear specs, and a highly efficient team or a no-code platform.
What takes the longest during app development?
The longest phases are usually backend development, third-party integration, and revisions due to changing requirements. Testing and debugging can also extend timelines.
Does app maintenance take time after launch?
Yes, app maintenance is ongoing. Expect to spend 5–20 hours per month on updates, bug fixes, and new feature development.
How long does it take to develop a game app?
Mobile game apps can take 6 to 12+ months, depending on the graphics, gameplay mechanics, and backend infrastructure involved.
How long does it take to create an enterprise-level app?
Enterprise apps with complex databases, integrations, and security layers typically take 9 to 18 months or longer.
How long does it take to update an app?
Simple updates can take a few days to a week, while major feature releases may require 3 to 8 weeks, including development and testing.
What is the timeline for app development if I use freelancers?
Freelancer-led projects often take 20–30% longer than agency-led ones due to coordination and availability issues. Expect 5 to 12 months, depending on scope.
How long does it take to develop an app with no-code tools?
With no-code platforms, you can launch a basic app in 2 to 6 weeks. However, customization and scalability are often limited.
Final Thoughts & Call to Action
Building an app is more like a marathon than a sprint. While it’s possible to launch in a few months, the average timeline is 4 to 9 months. Focus on clarity, planning, and starting small to avoid costly delays.
