Turning Ideas into
World-Class Apps
I'm Abin Antony, a passionate freelance mobile app developer from Kerala who has been crafting high-quality applications for 5+ years. I specialize in Flutter, React Native, and native iOS/Android development.
I work closely with clients from the first wireframe to App Store launch — combining clean architecture, beautiful design, and rock-solid performance in every project I take on.

What Users Say
Published reviews from the Play Store and App Store listings of apps I built — every one of them checkable on the store page itself.
"ProCalories completely changed how I track nutrition for my clients. The food database is huge — I find every Indian dish, including regional Kerala and Tamil Nadu recipes. My clients love the macro breakdown and the progress charts are crystal clear."
"Mealnix transformed our restaurant operations. Orders go directly to the kitchen display — zero verbal miscommunication. Our table turn time improved by 30% in the first month. The daily sales reports help me spot which items to push and which to retire."
"This app has made the auction process completely transparent. I can see the live bids on my phone from the farm itself — no more guessing. The price history charts help me decide which auction to hold my stock for. Best thing to happen to Kerala spice farmers in years."
Frequently Asked Questions
What clients ask before starting a project — cost, timelines, technology and how we'll work together.
General
What types of mobile apps do you develop?
I develop all types — e-commerce, healthcare, food delivery, EdTech, FinTech, social networking, on-demand services, and enterprise tools. If you can describe it, I can likely build it.
Do you work with clients outside Kerala?
Absolutely. While I'm based in Kerala, I work with clients across India, the Middle East, UK, Australia, and the US via remote collaboration. Timezone differences are never a barrier.
How do I get started?
Fill out the contact form or email abina35@gmail.com with a brief description of your app idea. I'll respond within 24 hours and schedule a free 30-minute discovery call.
Do you sign NDAs?
Yes. I sign NDAs before any detailed project discussion. Your idea and business information are kept strictly confidential.
What information should I have ready?
Ideally: what your app does, who the users are, 5 must-have features for launch, your approximate budget, and your desired timeline. The discovery call helps clarify anything that's not yet defined.
Technology
Which framework do you recommend — Flutter, React Native, or native?
For most projects I recommend Flutter — native-like performance on both iOS and Android from a single codebase. Native development makes sense for apps needing deep platform APIs or with existing native codebases. React Native is best when your team already knows JavaScript.
Can you build both the app and the backend?
Yes. I build full-stack mobile solutions — Flutter/React Native frontend + Laravel REST API or Firebase backend. One developer handling both ensures seamless integration and a single point of accountability.
Firebase or custom Laravel API — which should I use?
Firebase is faster and great for real-time features and MVPs. Laravel gives more control for complex business logic and relational data models. I recommend after understanding your specific needs.
Do you support both Android and iOS?
Yes. Flutter and React Native apps target both platforms simultaneously. For native, I develop Android (Kotlin) and iOS (Swift) separately.
What happens when iOS or Android releases a major update?
Major OS updates can break features or cause deprecation warnings. My maintenance plans include annual OS compatibility testing and updates to keep your app store-approved and running for all users.
Pricing & Timeline
How much does it cost to build a mobile app?
Simple apps: ₹1–3 lakhs. Mid-complexity (auth, payments, backend): ₹3–8 lakhs. Complex apps (marketplace, real-time): ₹8–20 lakhs. I provide a detailed, itemised quote after the free discovery call.
How long does it take to build an app?
Basic MVP: 6–10 weeks. Mid-complexity app: 12–16 weeks. Complex, full-featured app: 20–30 weeks. I provide a detailed project plan with milestones before we start.
What are your payment terms?
Milestone-based: 30% upfront (project start), 40% at midpoint (core features delivered), 30% on final delivery. For larger projects, more granular milestones can be structured.
Fixed-price or hourly billing?
Both. Fixed-price contracts give cost certainty for well-defined scopes. Hourly (₹3,000–₹5,000/hr) works for ongoing development or evolving scopes. I recommend fixed-price for most new apps.
Do you offer maintenance plans after launch?
Yes — monthly retainer plans covering bug fixes, OS updates, security patches, minor enhancements, and crash monitoring. Plans start at ₹15,000/month depending on complexity.
Process & Communication
How do you manage projects and keep clients updated?
Two-week sprints with a working demo at the end of each sprint. Shared project board (Trello/Linear), weekly video call updates, and a Slack/WhatsApp channel for day-to-day questions. You're always in the loop.
Will I own the source code and IP?
Yes, absolutely. Upon final payment, all source code, assets, and IP transfer to you 100%. No licensing fees or royalties — ever. This is specified in the contract from day one.
Do you provide UI/UX design?
Yes — wireframes and high-fidelity Figma mockups are included in most projects. If you have existing brand guidelines, I implement those. For complex brand identities, I work with a dedicated UI/UX designer.
What if we want to add features during development?
Scope changes are handled via a formal change request: I document the new requirements, provide a time and cost estimate, and we agree before proceeding. No surprise invoices.
