PWA Development in Portsmouth
Progressive web apps for Portsmouth businesses that want app-like behaviour without the app stores. Installs to the home screen from a link, keeps working when the signal drops, and ships updates the moment you deploy rather than waiting on a review queue.
Why this comes up
The problem
Publishing to two app stores means two builds, two review processes and a cut of every transaction. For most business apps that overhead buys nothing the web could not already do.
What you get

Working in Portsmouth
South East

PWA Development in Portsmouth — common questions
- Is a PWA as good as a native app?
- For most business use, close enough that the difference does not justify two native builds. Native still wins for heavy graphics, deep hardware access and background processing. If your app is forms, lists, scanning and sync, a PWA does the job.
- Does it work properly on iPhones?
- Yes, with caveats worth knowing before you commit. Apple supports installation and offline use, but its push notification and storage behaviour lags Android. If notifications are central to your product, that is a real constraint to weigh rather than discover later.
- How does offline actually work?
- Content and data are cached on the device and changes queue until the connection returns. What syncs, and what happens when two people edit the same record offline, are design decisions we agree with you rather than defaults.
- Can we put it in the app stores as well?
- Yes — a PWA can be wrapped and submitted. It is worth doing when customers genuinely search the stores for you, and not worth it when they arrive from your website.
- Do you work with businesses across Hampshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Portsmouth and the surrounding Hampshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Portsmouth businesses do you usually work with?
- Port, ferry and defence logistics systems, plus visitor operations for the waterfront attractions. Beyond that we work across Marine & Defence, Ports & Ferries, Higher Education, Retail and Tourism.
- Do you cover the areas around Portsmouth?
- Yes — we work throughout South East, including Southampton, Chichester, Brighton. Portsmouth is an urban area of roughly 240,000+, and we take on work across the wider Hampshire region rather than the city boundary alone.
