Why Choose Our PWA Development Company?

  • A full-cycle PWA development partner

    We don’t just write code to close tickets. We help you prepare the right scope (discovery + prioritization), build a realistic roadmap, and deliver a working product. No budget surprises. No timeline drift. No team turnover mid-project.

  • Offline-first performance and stability

    PWAs should stay usable even when the connection is slow or unstable. We build offline mode and caching so the main screens load fast and users can access critical content without waiting. The goal is simple: people open the app and get what they need, no matter the device or network.

  • Native app-like UX for retention and engagement

    A good PWA should feel close to a native app. We review critical flows, identify where users drop off, and refine the UI to improve retention, engagement, and conversion.

Testimonials

"Stormotion stood out because of their focus on Bluetooth-connected products. They weren't just app developers, they understood the unique challenges of building mobile app experience for hardware products. Their collaborative approach, technical expertise, and ability to quickly grasp the vision of the North Guardian app made it clear that they were the right fit."

"Stormotion has really delivered on their promises. They’ve been very transparent about their progress, flexible in reacting to changes, and solution-focused in overcoming challenges. If they didn’t know something, they would find out, which gave us great confidence in their ability to go the extra mile."

"I had meetings with 30 different agencies and the team at Stormotion gave me the most confidence to go forward. With them you feel like you've got a kind, knowledgable & conscientious team behind you. So I was 100% sure that they're going to be able to deliver our project!"

"We originally got in touch with Stormotion from our original app developer. And very soon we found real value in choosing Stormotion, because they previously had real valuable experience on the field – digital apps working in the realm of EV charging. So, it was really a no-brainer for us to to go with them."

"If you're thinking of going to Stormotion, you're going to have a very easy team to talk to, to communicate with, to understand what you want to do. They will tell you if you're barking up the wrong tree and are going to waste your time and money. I'd say "give it a go!" and I thoroughly recommend Stormotion."

"I highly recommend Stormotion as a service provider for app development. They're young, flexible, dynamic, creative and very fast. The cost of planning and implementation is also reasonable. As they use "pay as you go", have a good plan first – then the result also will be satisfactory."

"Given a tough budget and a lack of knowledge in our own engineering team, we quickly came to Stormotion. We had already worked together on previous projects, and I knew that, based on React Native, we could have one engineer responsible for it. That was just amazing because I could really focus on our customer side, knowing that the mobile application for the testers was in very good hands."

"Trust Stormotion. Work with them on your road map, on your technical debt. Also, expect feedback because the team is eager to do this. It's what I value and, I think, many startups value."

"The Stormotion team quickly became our team for everything Native app-related. It would be hard to name all the things that we built over the many years we worked together, but overall, I think we had a good partner who was able to adapt the way we worked, and the way they worked. So that we could ultimately build a product that had the quality that we wanted and with the speed that we wanted."

"Working with Stormotion was a blast! The Project Managers, and especially Alex, are always there for you when you need them to go the extra mile. And it's very easy to communicate with them. Whether it's something urgent or whether it's a bigger task, like building the structure of the architecture, I always felt like I was treated very well. Stormotion delivered a great app experience from day one."

Our Software Development Codex

1

Deliver solutions, not code.

We start by clarifying what the PWA must do for your users and your business. Then we suggest a scope that fits your goals.

2

Your best effort means nothing if it doesn’t work.

PWAs can behave differently across devices and browsers. We check the key flows under real conditions: weak internet, offline use, and data caching.

3

Slow is smooth. Smooth is fast.

Rushing early decisions often leads to rework, especially in migrations and legacy upgrades. We take time to decide what should work offline, what should be cached, and how the PWA should work.

4

Invented something? Great minds think alike.

Before we build custom mechanics, we check what the web platform already offers and what you already have in your systems. This keeps the product easier to support and extend.

5

Surface knowledge is surface value.

PWAs have limitations like offline storage, caching, and push notifications that work differently across platforms. We explain these details to you and offer solutions to overcome them.

Progressive Web App Development Process: Collaboration Models

Pre-Project

  • Discovery Stage

  • Planing

Agile Development

  • UX-Prototyping

  • Design

  • Development

  • QA & Testing

Transition

  • Maintenance

  • Handover

  • Next Iteration

From concept to release, with one team responsible for the result.

If you’re building a new PWA or upgrading an existing one, we adapt the work format to your situation: new build, migration, legacy upgrade, or integration-heavy internal tool.

Depending on your stage, our collaboration can include:

  • Product discovery: goals, main flows, scope, and release steps.
  • Offline mode and caching plan for key screens.
  • Migration or modernization plan to avoid breaking existing behavior.
  • Integration mapping (payments, CMS, ERP/CRM, internal services).
  • Analytics and retention tracking setup.

Our Excellence Pillars

Contact us
  • 4 months to MVP: a first version you can test

    We deliver an MVP PWA in 4months, focused on the main flows and the devices your users rely on. You get a working first version, so you can test it with real users and improve it based on data.

  • 3.7 years average engineer stay: stable team, clear ownership

    You work with the same engineers over time, which keeps context and reduces handovers. That consistency helps with long-term support, follow-up changes, and steady progress.

  • One team for your full web setup

    We can cover the PWA itself, related web parts, and supporting tools (admin panels, dashboards) with one team. This keeps the product consistent and makes future changes easier to coordinate.

Progressive Web App Development Agency: FAQ

What is Progressive Web App development?

Progressive Web App development is building a web application that works like a native app. A PWA runs in the browser but can be added to the home screen, open in a standalone window, work with limited connectivity through offline mode and caching, and use features like push notifications. It’s a good option when you want one product for desktop and mobile without maintaining separate native apps.

Can you migrate an existing website or app to a PWA without losing users or SEO?

Yes. Our Progressive Web App development services avoid a “big switch” and move in stages to keep key flows, accounts, and content structure stable. For SEO, we preserve URLs, metadata, and indexing signals, and ensure performance stays strong. Our team starts by reviewing what you have today, then offers a migration plan that reduces risk for both users and search visibility.

Are progressive web apps still a thing?

Yes. PWAs are used for products that need mobile web performance, offline access, and easier distribution than app stores. They’re popular for content and subscription products, field and internal tools, and cases where you want a single product across devices. The main decision point is not “are they popular,” but whether PWA functionalities and limits fit your product needs.

For which projects are Progressive Web Apps the right approach?

You should choose PWAs when you want one product for desktop and mobile, fast access without an app store install, and offline use for selected parts of the app. For example, content and subscription products (offline reading, saved content), or internal tools for teams working on different devices. If you need advanced features, a mobile app may be a better fit.

PWA vs native app: which one should I choose?

Choose a PWA when your product is primarily a web experience, you want broad device coverage with one codebase, and offline access plus an app-like feel is “enough.” Choose native when you need advanced device features, strong background behavior, or OS-level integrations across all platforms.

Can a PWA work offline and send push notifications?

Yes, in many cases. As a part of our PWA development services, we handle offline mode through caching and storing selected data locally, so important screens still work when connectivity is weak. Push notifications are supported in many modern browsers, but behavior varies by platform and browser, so we treat it as a feature that must be tested in your target setup. If offline use and notifications are critical to the product, we test them throughout development.

How much does it cost to build a Progressive Web App?

Cost depends on scope, integrations, and complexity. Our development unit (full-time developers plus part-time QA, UX/UI designer, and PM) typically costs $10,000-15,000 per month. To develop an MVP, we need 3-4 months, and it costs $30,000-60,000. A complex PWA can take 5-6 months to build and costs $50,000-90,000. Contact our Progressive Web App development company and we’ll prepare the Project Cost Estimate for you.

How long does it take to build a Progressive Web App?

It depends on scope and complexity, but an MVP PWA typically takes 3-4 months. A larger platform with backend APIs, admin panels, integrations, and compliance requirements can take 5-9 months. We always start by defining the main flows and the first release scope, then build in steps.

What are the limitations of PWAs on iOS and Android?

PWAs work well on modern browsers, but support differs by platform. Android (Chrome) offers broader PWA features, including easier installation and stronger support for app-like behavior. iOS (Safari) has improved, but some features can be limited or behave differently, and system updates can affect caching and storage. That’s why we confirm target devices early and plan the feature set around real platform behavior.

Can a PWA integrate with our existing systems (payments, CMS, ERP/CRM)?

Yes. Many PWAs rely on integrations. For content and subscription products, this often includes payments and a CMS. For internal and workflow tools, it’s usually ERP/CRM and internal services. We define system logic, how users authenticate, and what roles and permissions you need. Then we implement and test the integrations so the PWA works as part of your business.
