Define the terms
A web app runs through a browser. A PWA adopts additional capabilities such as installation or offline behaviour where supported and implemented. Native applications target a specific platform; cross-platform approaches also exist.
These labels do not establish quality or completeness. Authentication, data protection and reliability depend on implementation. An installable application may still require connectivity for some operations.
Compare the actual workflow
A portal opened occasionally through a link may start in the browser. A tool used daily on the same phone may benefit from installation. If a core feature depends on sensors or background work, verify that precise capability.
| Requirement | Question to check |
|---|---|
| Access | Direct URL, installed icon or store distribution? |
| Devices | Controlled company phones or varied personal devices? |
| Connectivity | Offline reading or creating and editing records? |
| Features | Which notifications, sensors or device capabilities are essential? |
| Maintenance | Which browsers and operating systems will be supported? |
Offline means more than opening a screen
Imagine two operators editing the same request without a connection. Which change should prevail when both reconnect? That requires a rule. Caching screens does not automatically handle conflicts, duplicates or a lost device.
Specify which data is available offline, for how long and which actions may wait. Distinguish data stored locally from data synchronised with the service. Test connectivity loss, restarting and reconnecting.
Three illustrative decisions
Quote portal: a customer follows a link, reads a proposal and responds. A web app is an approach to evaluate when no specialised device feature is necessary.
Field service tool: lists, photographs and updates over an unreliable connection. A PWA may be a candidate, but requires real-device tests and synchronisation rules.
Device-centred service: continuous background work or specialised integrations may favour dedicated mobile development. These are examples of reasoning, not compatibility guarantees.
Test the risky feature first
Before building the complete product, create a small proof of the highest-risk function, not only the most attractive screen. Check installation, permissions and behaviour on the target device. Changing direction is less costly before the whole product exists.
Separate essential and optional capabilities. Make backend, access, notifications, publication and maintenance explicit scope items. A visual prototype supports discussion; technical acceptance establishes whether the solution works under the required conditions.

The fitness concept shows an interface direction. It does not establish backend, offline or store distribution capabilities.
