A website that works like an app, even without internet

A PWA (progressive web app) is a website users install on their home screen. It opens fast, sends notifications and keeps working offline. You get one codebase for iOS and Android, with no app-store review in the way.

Quote and schedule after your brief

Who it's for

  • Field, warehouse and delivery teams that often lose signal
  • Businesses that want an app but not the cost of two native builds
  • Services with repeat customers who need quick login and notifications
  • Startups testing an idea before committing a bigger budget

Problems we solve

Native iOS and Android apps cost too much, and we don't know yet if people will use one

We build one PWA from a single web codebase that runs on both systems. We start with a pilot and a KPI you can measure.

Our staff work offline and lose data

Data is saved on the device and synced when the connection returns. We design for conflicts too, such as two people editing the same record.

Customers won't download an app for one order

A PWA installs from the browser in one tap. There is no store visit and no large download.

Our site is slow and visitors leave

We cache key assets with a service worker (a background script in the browser) and measure speed before and after.

What's included

  • Scenario analysis: what must work offline and what can't
  • Mobile and tablet interface design
  • Web app manifest: icon, name, colors, full-screen mode
  • Service worker and caching strategy
  • Offline mode with local storage (IndexedDB) and sync
  • User login and roles
  • Web Push notifications where the browser supports them
  • Integration with your CRM, payments or database
  • Testing on real iOS and Android devices
  • Deployment, domain, HTTPS and handover of all access to you

How we work

01

Brief and requirements

You describe the task and current workflow. We clarify requirements, choose a first stage and prepare a quote.

02

Scenarios and prototype

We decide what works offline and design the screens. You see a prototype before development starts.

03

Pilot build

We build the core workflow and set a KPI you can measure. Payment is in stages.

04

Real-device testing

We test on different phones, on iOS and Android, with weak and dropping connections.

05

Launch and handover

We deploy and hand over accounts, files and access. Everything is yours under the agreed terms.

Scope and limits

  • We don't promise a PWA replaces every native feature, because access to some device functions is limited
  • We don't guarantee identical notification behavior across all iOS versions and browsers, so we test it separately
  • App Store and Google Play listings are not part of a PWA build. They are a separate service if you need them

FAQ

How is a PWA different from a regular website?

A PWA installs on the home screen, works offline and can send notifications. To users it feels like an app. For you it means one codebase instead of two.

Will it be in the App Store or Google Play?

Not by default. It opens from the browser. Google Play accepts PWAs through a wrapper, and we can add that separately. The App Store is harder because of Apple's requirements.

What will work offline?

We decide that together at the start. Viewing data and entering records with later sync are usually possible. Payments and anything needing a live server do not work offline.

What do you need from me?

A description of the process, sample data, access to your CRM or database if you have one, and one person who makes decisions. Logo and brand guidelines help if you already have them.

How much does it cost?

We prepare a quote after reviewing your brief and requirements. A first stage can cover: one main workflow; Browser install and home-screen icon. Scope, payment and schedule are agreed before work starts.

Who owns the code and accounts?

We agree on the handover of code, materials and account access before work starts. Third-party licences and services are listed separately when needed.
