A progressive web app (PWA) is a web app that installs on a phone’s home screen, like an app. It can work without a connection and send its changes once the connection is back. It needs neither the App Store nor Google Play, and it shares its code with the web version.
A PWA fits when your team works away from the office, with a network that can’t always keep up.
Inspections, deliveries or job sites. Data entry keeps going when the signal drops.
At the back of a store or between two metal shelves, the signal is often weak.
An icon on the home screen, without going through an app store.
Your clients install your software in a few seconds, on all their devices.
An icon, a name and a splash screen in your colors.
The useful screens and data stay on the device. Entries wait for the connection to come back.
Changes are sent on their own once the connection is back, without the user having to think about it.
Reminders and alerts on the device. On iPhone, the app must be installed first.
A single app to maintain, for desktop and phone alike.
The new version arrives the next time the app opens, with no app store approval.

For most business tools, a PWA is enough and costs less. There is only one version to maintain, with no commission and no approval. A native app becomes useful when you need full access to the hardware, such as an RFID reader.
Yes. On iPhone, you install it with the Share button in Safari, then “Add to Home Screen.” Notifications require the app to be installed, and some sensors, such as NFC, remain limited.
The rule is decided at the planning step. Depending on the data, the last change wins, or the software flags the conflict and a person decides.
Often, yes. Installation and offline mode are added to the screens that need them, without rewriting the rest.
