What is a progressive web app and what can it do for staff?

You open the address in a browser, the browser offers Add to Home Screen, and a tap later an icon sits beside the phone’s other apps. It opens without the address bar. A splash screen shows first. No store is involved.

Behind this sit two files. A manifest names the app, icon and colours, while a service worker is a small script between the app and the network that decides what to serve offline.

Staff install no updates. When you release a change, the next launch picks it up quietly, so a fix to a checklist reaches every phone without a reminder message or a store review.

Take a warehouse team that checks transfer slips. The app caches the slip list, so a dead spot between the pallet racks does not blank the screen, and edits wait in a queue until the signal returns.

A field sales rep can open the price list on a train, and a supervisor gets an alert when leave requests land, and neither needs a store review.

Rollout is simple. Send the link by message. Staff install it in seconds.

iPhone support is the first catch. Installing works but follows steps through the Share menu, push alerts need the app added to the home screen, and some background features are weaker than on Android.

Hardware is the second. Bluetooth label printers, NFC cards, scanners wired into the phone and deep sensor access are patchy or missing in browsers, although camera and GPS location work well.

Third comes the store listing. Customers search the app stores, not the web, so a progressive web app must be packaged for some stores with extra work and cannot count on being found.

Desk users need a plain web app. A PWA fits staff who need the icon, alerts and short offline spells, while native suits heavy hardware use, long offline work or customers who expect a store listing.

Ask for the one device that matters most. If every field person carries a rugged Android handset with a scanner, native may serve better, but if staff use their own mixed phones, a PWA reaches them all.

You can start with a PWA and move to native later, but only for the few screens that need Bluetooth, NFC or a wired scanner.

Open a prototype on the three phones your staff really carry, including the oldest, then install it, switch to aeroplane mode, reopen it and complete one task.

Ask for the list of features that fail on iPhone, because a vendor who hands you one is easier to trust than a vendor who says everything works.

Write the must-have hardware on one line. If that line names a Bluetooth printer, choose native before anyone designs a single screen, since redoing the layout later wastes every wireframe drawn so far.
