An app does not always need distribution through an app store. A progressive web app, or PWA, uses web technology and can offer app-like capabilities under certain conditions. A native app is built for a particular platform. Cross-platform approaches also exist. Your workflow should determine the choice.
Begin with the people using it
Does your team use managed Android devices, or must customers join from many different phones? Can you install software on those devices? Do people also need the same workspace on a laptop? Browser access can simplify distribution, but it does not prove every required capability will work.
List the devices and operating systems you will actually support. Test those combinations. A demonstration on one recent phone is not evidence for the entire user base.
Compare capabilities, not labels
MDN's PWA documentation describes installation and offline capabilities available to web apps. Exact support varies by browser and platform, so do not assume identical behaviour everywhere.
Build a small prototype around the capabilities your process cannot lose:
- Camera access, files and any scanners or specialist hardware.
- Notifications and behaviour when the app is not open.
- Offline reading and safe synchronisation.
- Sign-in, device management and business security.
Offline operation needs its own design
An installed app is not automatically a reliable offline app. Decide which information is stored locally, how long it can remain there and how conflicting changes are resolved. Clearly distinguish a received job sheet from one still waiting to upload.
When a supplier promises offline support, ask for a concrete demonstration: enable flight mode, complete an assignment, close the app, reopen it and reconnect later.
Compare the whole lifecycle
Include distribution, compatibility testing, updates, support and the availability of people who can maintain the solution. A cheaper first release missing an essential capability is not necessarily the economical option.
Record the decision in a short table of must-haves, test outcomes and known limitations. That is more useful than a blanket preference for one technology.
Prove the riskiest assumption first
Test the most uncertain capability before expanding the project. The result supports a defensible platform decision. We can help with this comparison through custom mobile apps. Continue with our guide to digital job sheets for a practical field-service example.
