01The approach
Our approach to web app development.
A lot of the apps we get asked to build should not be in a store at all.
What a web app gets you
- New users reach something useful fast90s to value
- They come back on day thirty+41% retention
- A cold start that feels instant-1.9s cold start
- It keeps working in lifts and dead zonesOffline-first
- No store review in your release plan100% pass rate
- The same senior engineers, start to finish0 swaps
Read the full approach
An internal tool used by forty people, a dealer portal opened once a fortnight, a booking flow that arrives from a link: each of those pays the full cost of a store listing, two review cycles and an install prompt, and gets very little back for it.
A progressive web app skips all of that. It installs to the home screen, works offline, sends push on both major platforms now, and updates the moment you deploy rather than when a reviewer gets to you. For a large share of business software that is simply the better answer.
What it will not do is replace a native app where the hardware matters, and we will say so early. Background location, deep camera control, HealthKit and anything running for hours in the background still need a real app. The point of asking the question in week one is that you only pay for a store presence when it earns its place.
Where a store listing stops being worth it
- An internal tool with a known set of users
- A dealer or partner portal opened occasionally
- A flow people arrive at from a link or a QR code
- Anything that changes weekly and cannot wait on review
- A first version testing whether an app is wanted at all

03Process
Our web app development process.
Five stages, and you are using it in a browser from week four rather than waiting on a build.
01DecideWeek 1
Web app or real app, settled first. We check what the product actually needs from the device. If it needs background location or deep camera work we say so and cost a native build instead, because a web app cannot do those things well.
02DesignWeek 2–3
Designed as an app, not a site. App navigation, not a menu bar. Offline and empty states drawn alongside the happy path, because in a web app those are the states people actually hit.
03BuildWeek 3–8
In your browser from week four. Deployed continuously to a staging URL you can open on your own phone. Service worker, caching and queued writes built in from the start rather than added once it is too late to restructure.
04HardenWeek 8–10
Measured on the slowest device. Load and interaction time on the phone you agreed to support, not the developer's laptop. Installability, push and offline behaviour tested on real Android and iOS handsets.
05ShipOngoing
Deploy whenever you want to. No submission and no review queue, so a fix reaches everyone the same day. Fourteen days of cover included, and a retainer afterwards only if you want one.
Stage 02 · Design
04Included
What we deliver.
01Installs without a store
Added to the home screen from the browser. No listing, no review queue, no forty per cent of users refusing to install anything.
02Updates the moment you deploy
No submission, no staged rollout, no waiting on a reviewer. It matters most for the things that change weekly.
03Works with no signal
Cached shell, queued writes and honest empty states. Offline is designed in rather than discovered in a lift.
04One build, every device
Android, iOS and desktop from the same codebase, including the laptop half your internal users are actually on.
05Measured on a mid-range phone
Load and interaction time checked on the slowest device you support. A web app that is slow there is a web page, not an app.
06An honest limit, stated early
Background location, deep camera control and HealthKit still need a native app. We tell you that in scoping, not after.
05The work
Installable web apps and the systems behind them. The published examples are in the portfolio.
What we build on the web.
Web software, end to end.
Progressive web apps, dashboards, and the APIs underneath them.
- Progressive web apps, installable and offline
- Admin panels and reporting dashboards
- Dealer, partner and customer portals
- APIs, integrations and data pipelines
Much of our product work sits under an NDA. Everything in the portfolio was built by the same engineers and is live right now, go and prod it.
06Why Syscodes
What clients say after being quoted for an app they did not need.
Why teams pick us for web apps.
web vs native settled
We ask whether you need an app at all
A store listing costs two review cycles and an install prompt. For a lot of internal and B2B software it buys nothing, and we would rather say that in week one.
to every user
Releases stop being an event
No submission, no reviewer, no staged rollout. A fix reaches every user the same day you merge it.
first, not patched on
Offline is designed, not discovered
Cached shell, queued writes and honest empty states from the start. Retrofitting offline means rewriting the data layer.
devices, not a laptop
Measured on cheap hardware
Load and interaction time on the slowest device you support. A web app that is slow on a mid-range phone is just a website.

Senior engineers, no bench
The person in your scoping call writes the code. Nothing is handed down to someone you have never spoken to.
ownership from day one
Your code, your hosting
The repository is yours and it runs on infrastructure you control. Leaving us costs you nothing but the notice period.

What is a progressive web app, in plain terms?
A website built so it behaves like an app. It installs to the home screen from the browser with no store involved, opens without browser chrome, works with no signal, and can send push notifications on both Android and iOS. For a large share of business software it is indistinguishable from a native app in daily use.
When do we actually need a native app instead?
When the product depends on the hardware. Background location running for hours, deep camera control, HealthKit, Bluetooth peripherals, heavy on-device processing, or anything that must run while the phone is locked. If your requirements sit there we will say so in week one and cost a native build instead.
Can a web app work offline?
Yes, and properly, if it is designed that way from the start. A cached shell, queued writes that sync when the signal returns, and honest states when there is nothing to show. Retrofitting offline afterwards usually means rewriting the data layer, which is why it is a week-one decision.
Do push notifications work on iPhone?
Yes, for installed web apps, though the user has to add it to the home screen first and the permission prompt behaves differently from a native app. If push is central to how your product works rather than a nice-to-have, that is worth weighing in the native-versus-web decision.
Is a web app cheaper than a mobile app?
Usually, and for two clear reasons rather than vague ones: there is one build instead of two, and there is no store process, no review cycles and no listing to maintain. The saving is real but it is not the whole justification, and we would rather you chose it because it fits than because it is cheap.
How do users find it if it is not in a store?
The same way they find your website, which for internal tools, dealer portals and link-driven flows is how they were always going to find it. If discovery through the App Store or Play is genuinely part of your acquisition plan, that is an argument for a real app and we will say so.
What does web app development cost in India?
There is no price list, because scope sets the number. We scope every engagement after a free consultation and put the figure in a written proposal, along with what would move it and what a native build would have cost instead.
Who owns the code and where does it run?
You own the repository from the first commit and it runs on infrastructure you control. There is no platform account to transfer and no store relationship to move, which is one of the quieter advantages of not being in a store at all.
Where are you based, and can you work with us outside Kolkata?
Do you work with clients outside India?
Yes. We have delivered in 20+ countries across five continents, and we commit to four guaranteed overlap hours with US Eastern (18:30–22:30 IST), with a full overlap for the UK and Europe. The names are in the contract.
