Mobile app development company in Ahmedabad: Flutter & React Native.
Cross-platform iOS and Android apps in Flutter and React Native, from business analysis to store release. We build iOS and Android apps with Flutter and React Native, so one codebase serves both platforms without giving up a native feel. From business analysis and UX to the Laravel or Node.js API behind the app, store release and ongoing support, one team owns the whole product.
A multi-location point of sale and business management platform for restaurants, cafes and retail stores: fast checkout at the counter, table bookings, inventory, purchasing, staff and reports in one web app, with companion apps for terminals, kiosks and handheld devices.
A consumer fintech platform for paying bills and recharges from a credit card, moving wallet money to cards, banks and UPI, and comparing credit cards with calculators and eligibility tools, delivered as a website, an admin panel and a React Native app.
A family of mobile apps for a cloud POS platform: a Flutter POS app with phone and terminal layouts, a kitchen display and a self-order kiosk mode, plus React Native (Expo) apps for counter sales, customer kiosks, table ordering and inventory counts.
A resale marketplace where people send in pre-loved clothes and shoes, the operator grades, prices and lists each piece, and sellers earn payouts or donate part of the proceeds to verified NGOs.
A fantasy cricket app where users pick matches, build teams with a captain and vice-captain, join contests and manage a wallet, with KYC and Indian tax rules designed in from the start.
A React Native (Expo) companion app for an AI content platform: users create AI-generated social posts, schedule them, manage their organisation and community, and check analytics on the go.
No black boxes. You always know what is happening, what is next, and what it costs.

Why DayDecoder
A senior partner, not a ticket queue.
Big agencies hand you to an account manager. We keep the founder in the room and one team on your product, from the first sketch to the first paying customer.
“I don't just execute tasks. I architect systems, design robust database schemas, build high-performance backend logic, and create responsive front-end experiences.”

Prakash is an amazing guy to work with and he is really passionate in his work. He is a person with can-do attitude and very approachable.

Not sure which one? Tell us about the project and we will recommend one honestly, even if it is the smaller option.
Dedicated team
A partner who stays with the product.

Typical length
Ongoing, billed monthly
What you get
A senior developer or small team working inside your product, weekly demos, shared Slack/Jira.
We agree the brief, milestones, and deliverables up front. You get a predictable engagement for a defined piece of work — a new product, a rebuild, or a well-bounded feature set.
Best for
MVPs, launches, and projects with a known scope.
Typical length
Usually a few weeks to a few months, depending on scope
Flexible help when the work is still taking shape.
Use us for support, reviews, integrations, or exploratory work. You stay in control of the hours; we stay available and honest about what the time is buying.
Best for
Maintenance, rescue work, and short bursts of specialist help.
Typical length
As needed
What you get
Pay only for hours used, time logs, quick fixes, reviews, and integrations.
Both. We pick per project: Flutter when you want one polished UI across phones, tablets and counter terminals, React Native (often with Expo) when your team already works in JavaScript or React. Either way you get one codebase for iOS and Android.
Both ship real native apps. Flutter draws its own UI, which suits pixel-consistent, animation-heavy or hardware-connected apps like POS terminals. React Native uses native components and fits teams that share code and skills with a React web app. We recommend one after the discovery call, based on your product and team.
Yes. We have built Flutter apps with separate phone and terminal layouts, a kitchen display and a self-order kiosk mode in one codebase, with receipt printing over Bluetooth and network printers.
Yes. Most of our apps talk to a Laravel or Node.js API and admin panel that we build alongside them, so the app, API and dashboard are designed together.
Yes. We handle builds, signing, store listings and review submissions, and can set up separate test and production builds so you can try changes before they reach customers.
It depends on scope. After a free discovery call we send a written proposal with a fixed quote (or a monthly rate for a dedicated developer), so you know the cost before anything starts.
A focused MVP is usually a matter of weeks, larger platforms a few months. Your proposal includes a milestone plan with dates.
Yes, we are happy to sign an NDA before you share details. Once the project is paid for, the source code and IP belong to you.
Yes. You get regular updates and demos of working software during every sprint, and access to the staging site.
Yes. We offer ongoing support and maintenance on an hourly or monthly basis, and we can also handle SEO, social media, and ads to grow the product.
We are based in Ahmedabad, India, and led by Prakash Tank. You work directly with the people building the software, not a rotating account team.
Yes. Our hours are built around those regions: morning updates for US clients, afternoon overlap with Europe and the UK, and early-morning calls with Australia.
Laravel and PHP are the core. We also work with React, Next.js, Vue.js, Node.js, PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, AWS, Google Cloud, Kafka, Docker and Kubernetes, Flutter and React Native for mobile apps, plus OpenAI and Claude for AI features.
Yes. We add chatbots, LLM-powered search, document and data extraction, and workflow automation to existing Laravel, Node.js, and web applications, connected to your own data rather than a generic tool.
We build with OpenAI and Claude models, use LangChain and LlamaIndex to connect them to your documents and data, and add vector search and prompt engineering where answers must stay accurate. The model is chosen for your use case, budget, and data requirements.
We agree what data an AI feature may use before building it, send only the data a task needs to any third-party model, and are happy to sign an NDA before you share details.
