How much does it cost to make an app?

A medium-sized app with sign up and 5-10 screen would cost about $4,000-$6,000 , and will include executables for both Android and iOS. If the app is large and contains complex functionality, such as chats, audio/video playback, slick UI, the price can be $10,000 and above. However, these prices are very competitive because I develop on Flutter. My deep knowledge of the framework helps me to reduce development costs comparing to other agencies, keeping the app quality high.

How long does it take to create an app?

Usually, it takes 2-3 months to make a good medium sized app . That includes defining requirements, setting up the environment, publishing the app to Apple AppStore and Google Play Store. More complex apps could take up to one year to get released. But I always advise releasing an MVP version of the app as soon as possible.

Expert Freelance Mobile Developer for iOS, Android, and Cross-Platform Projects

Your Freelance Mobile Development Partner:

I am a freelance iOS/Android developer, technical consultant, and enthusiastic open-source contributor. With vast experience collaborating with global clients, I extend my iOS/Android development services to businesses of all scales — from startups and agencies to fellow freelancers.

Quality at the Forefront:

I commit to delivering top-notch, responsive work, compatible across a broad spectrum of devices. Every project I undertake boasts robust architecture, accurate documentation, and is designed for easy maintenance and scalability.

Coding Excellence:

Upholding high code quality is paramount to me. I employ static code analyzers and emphasize well-documented, readable code. This approach not only future-proofs the application but also facilitates smooth collaboration with other developers.

My Journey:

Transitioning from a C# developer, I dived into iOS app development during the iOS 6 era. By 2019, my focus expanded to cross-platform development with Flutter. Throughout my freelance journey, I’ve crafted over 40 applications, culminating in a compelling portfolio. Here’s a glimpse into some standout projects:

Opendate

iOS app for music ticketing

Leafarise

iOS/Android gardening app

Explorial

iOS/Android scavenger hunt game

Sometimes I contribute to other open-source projects and create my own. Check out my Github profile for other open-source contributions.

Skills

Mobile development

Flutter

Swift

I’ve been an iOS developer for many years, making apps and games for iPhone and iPad. I used Objective-C until 2014. In late 2014, I started using Swift because it’s simpler and faster. Using Swift, I could make apps quicker, saving my clients 10-20% in costs.

In 2019, I began using Dart/Flutter. With Flutter, I can write one app that works on both Android and iOS. This saves my clients up to 40-50% and gives them apps for both phone types.

For making apps, I use tools like Visual Studio Code, Xcode, Android Studio, and Git (like GitLab, GitHub, and Bitbucket). To make sure apps run fast, I use Xcode Instruments and Flutter DevTools.

Backend development

Firebase

TypeScript

node.js

Mobile App Expertise:

I specialize in iOS and Android development, bringing your app ideas to life with precision and flair.

Backend Proficiency:

Beyond mobile development, I possess a strong command of server backend technologies. Whether you already have your server setup or need assistance from the ground up, I can collaborate seamlessly to design and deploy robust APIs—primarily using REST API (JSON). Plus, I’m seasoned in using WebSockets to facilitate real-time data exchanges.

Diving Deep with TypeScript & Firebase:

Leveraging my in-depth understanding of TypeScript, I craft dynamic backend logic for server apps, especially on Google Firebase. Having realized more than ten projects on this platform, I’ve harnessed the full power of Firebase features—from Cloud Firestore and Cloud Functions to Realtime Messaging and Analytics. If you’re starting, consider Firebase; it’s user-friendly, scalable, and offers an all-encompassing backend solution.

Legacy Expertise with Parse.com:

Between 2014-2017, I was an avid user of Parse.com BaaS. With the evolution of Parse Server, I smoothly transitioned Parse.com backends to self-hosted Parse Server instances. This journey enriched my skills with MongoDB and gave me firsthand experience with server-side node.js applications.

Let’s Collaborate:

Whether you’re a startup aiming for a robust mobile presence or an established firm seeking to enhance your backend systems, I’m here to help. Let’s transform your visions into vibrant digital realities.

Design-to-Code Expertise:

I pride myself on transforming designs into high-performance code, always respecting the original vision of your designers. Recognizing that design and development are two sides of the same coin, I strive to merge them seamlessly for an unparalleled user experience. It’s worth noting that iOS users have a discerning eye for UI detail, and I’m committed to meeting their high standards.

Adhering to Platform Guidelines:

For iOS apps, I strictly follow the Apple Human Interface Guidelines. If a proposed design suggests unconventional controls or a UI pattern unsuited for compact iPhone displays, I’ll provide feedback and offer alternative solutions aligned with Apple’s recommendations. For Android apps, the guiding principle remains the same, adhering to Material Design.

A Note on Design:

While I can craft straightforward interfaces using standard iOS and Android controls, I’m not a designer by profession. For a truly captivating UI, I recommend collaborating with a dedicated design expert.
