What we build

Software your business actually runs on.

Four kinds of build, one way of working. Each one ends the same way: live, in your name and looked after once it launches.

01 / Mobile apps

One app for Android and iOS.

Built in Flutter from a single codebase, so both versions launch together and stay in sync with every update.

  • App ready for the Play Store and App Store
  • Admin panel to manage it
  • Login, payments and notifications wired in
  • Source code in your name
  • Flutter
  • Android
  • iOS
02 / Web apps

Web apps and customer portals.

Web apps and portals where your customers reorder, pay and download invoices on their own. On your domain, on any phone or laptop, built with React and Next.js.

  • Live on your own domain
  • Self-service for your customers
  • A dashboard for your team
  • Hosted on your server
  • React
  • Next.js
  • Node.js
03 / Business software

Replace the spreadsheets and the chasing.

Internal tools, CRMs and dashboards built around how your team already works, not the other way round.

  • One place for orders, stock, bookings, leads or staff
  • Roles, so staff see only what they need
  • Reports you can read
  • Exports to Google Sheets
  • NestJS
  • Laravel
  • PostgreSQL
04 / AI + WhatsApp

Your app talks to customers on WhatsApp.

AI replies, order updates and follow-ups go out on WhatsApp, and every conversation is logged inside your app.

  • WhatsApp Business API set up
  • Automated messages and alerts
  • AI replies (OpenAI / Gemini)
  • Everything logged in your app
  • WhatsApp Business API
  • OpenAI
  • Gemini

One studio

One team. Instead of four hires.

Design, development, hosting and support under one roof. One point of contact, one written quote, one team that answers for the result.

Our stack

The whole stack.
Picked for your product.

We use proven, widely used tools, from the app in your customer's hand to the server behind it. That keeps your code easy to hand over, so you're never locked in to us.

    Talk

    Message us on WhatsApp or call. We learn how your business works today.

  2. Step 02

    Plan

    You get a written scope, the screens list, a clear written quote and a timeline before any work starts.

    We take it live on your server, hand everything over and stay on to watch it and support it.

What you get

All it needs. Nothing held back.

An app, a web app, a dashboard or all three: we design it, build it, set it up and hand it over as one project, on one written quote. The code, the data and the server are yours, and there are no hidden fees after.

  • Written quote before we start

    Scope, screens list and timeline, agreed in writing before any work begins.

  • You own the code, data and server

    Everything is in your name, and we hand all of it over to you.

Before you hire

8 questions to ask any app developer.

Whoever you hire, ask these before any work starts. Here are our answers, so you can compare.

  1. Will I get a written quote before work starts?

    Yes, in writing. You get a written scope, a screens list, a clear quote and a timeline before any work starts.

  2. Will I see the screens before you write code?

    Yes, and you approve them. We design the screens first. You ask for changes and approve them before we build.

  3. Can I try the app while it's being built?

    Yes, on your phone. You get working builds to try on your own phone as we go.

  4. Who owns the code, the data and the server?

    You do. Everything is in your name, and we hand all of it over. No lock-in.

  5. What happens after launch?

    We stay on. We watch the app, fix issues and keep improving it with you.

  6. Who will I actually talk to?

    The people building it. You talk directly to the team designing and building your app, not a middleman.

  7. Is my app secure and backed up?

    SSL, backups, firewall. Every app we launch gets an SSL certificate, nightly backups and firewall protection.

  8. What will you build it with, and why?

    Proven, widely used tools. Flutter for Android and iOS, React and Next.js for the web, and Node.js, NestJS or Laravel behind them, so your code is easy to hand over.

Have a question that isn't on the list? Ask us on WhatsApp

Security & reliability

Secure by default. Reliable by design.

Every app we launch is set up with an SSL certificate, nightly backups and firewall protection, and we keep a close watch on it after go-live.

01 / Uptime

99.2%Uptime on every project.

Every app we launch runs on a production setup that we keep watching after go-live, so your team and your customers can rely on it.

02 / Encryption

SSL on every app.

Every app we launch gets an SSL certificate, so logins and data travel over a secure https connection.

03 / Backups

Nightly backups.

Your database is backed up automatically, every night, on every app we launch.

04 / Protection

Firewall & intrusion protection.

A firewall guards the servers we run, and repeated bad login attempts are blocked automatically.

05 / Recovery

Auto-restart, watched after launch.

If a process crashes, your app restarts automatically. And we keep a close eye on it after go-live.

06 / Ownership

You own it all.

The code, the data and the server are yours. We hand over everything, so you are never locked in.

Ask on WhatsApp
How much does app development cost in India?
It depends on the screens, features and integrations your app needs, so there is no fixed price list. Tell us your idea on WhatsApp. We'll ask a few questions, then send a written scope and a clear written quote before any work starts. No hidden fees, and no surprise bills later.
How long does it take to build an app?
It depends on scope. Before we start, you get a written timeline with milestones. While we build, you get working versions to try on your own phone.
Who owns the app and the code?
You do. The code, the data and the server are yours, and we hand over everything. There's no lock-in.
Will you sign an NDA?
Yes. We're happy to sign your NDA before you share the details of your idea.
What happens after launch?
We stay on. We watch the app after go-live, fix issues and keep improving it with you. We don't build and disappear.
Which technology will you use?
Usually Flutter for mobile apps (one app for Android and iOS), React or Next.js for web apps, and Node.js, NestJS or Laravel behind them. We pick what suits your product and explain why in plain words.
Can you build a CRM, dashboard or internal tool?
Yes. Custom business software is a core part of what we build: CRMs, dashboards and internal tools for orders, stock, bookings, leads or staff, with roles for your team and reports you can read.
Can the app work with WhatsApp?
Yes. We connect apps to the WhatsApp Business API for order updates, alerts and AI replies, and we've shipped 50+ custom WhatsApp builds in production.
Can the same team bring customers to the app?
Yes. TechnicalGuider also manages Meta and Google Ads. On Meta, we connect your app and CRM through the Conversions API, so campaigns learn which leads became paying customers.
Where are you based? Can we work remotely?
We're based in New Delhi and work remotely with businesses across India, from the metros to Tier-2 and Tier-3 cities, plus select clients in the US, Singapore and the UAE. Reach us on WhatsApp or by phone, Mon–Sat, 10 AM–7 PM IST.
