Choosing between a web app and a mobile app begins with the user's job, not a preference for a particular technology. Different delivery approaches create different access, device and maintenance responsibilities. A browser-based product can be appropriate for one workflow while an installed app may better support another. The decision should be based on demonstrated requirements and trade-offs, with uncertain capabilities tested before the project commits to them.

Describe when and where the product is used

Write the user's device, environment and frequency of use. A hypothetical appointment-planning tool may be used occasionally by customers but daily by staff. Customers may prefer opening a link without installing anything; staff may need a persistent workspace. These are different contexts that could justify different interfaces within the same service.

Identify whether use happens at a desk, in the field or during another activity. Include interruptions and unreliable connectivity. Avoid assuming that mobile use automatically requires an installed app. Conversely, do not assume a browser can provide every device capability consistently. The required behaviour and target devices need investigation.

List actual device requirements

Specify camera use, notifications, location, file access or other capabilities only when they serve the journey. Explain what each is needed for and whether an alternative is acceptable. For an inspection workflow, attaching a photo may be essential while continuous location tracking may be unnecessary. Minimise permissions and describe them clearly to users.

Confirm support through a technical evaluation on the intended devices. Capabilities and restrictions depend on the environment and can change, so avoid a timeless promise about what every platform supports. A proof of concept may be the right first deliverable for a critical feature. Keep the result tied to the tested configuration rather than a general statement about web or native products.

Model offline and synchronisation needs

Distinguish loading previously viewed information from completing work without a connection. Offline editing creates questions about conflicts, duplicates and recovery. A hypothetical staff scheduling app might need to display the last known plan, but changing appointments offline could require more careful coordination. Define the actual requirement before treating offline support as a checkbox.

Explain how users know whether data is current, saved locally or confirmed by the service. Plan what happens when two people edit the same item. Test reconnection and interrupted actions, not only a successful initial load. The delivery approach should support the required consistency model, but no interface label solves the underlying data decisions automatically.

Compare access and distribution

Consider how users find the product, sign in and receive updates. A public browser link may suit occasional access. An installed app introduces distribution and release-management work that should be included in the scope. Internal tools may have different access requirements from public consumer products. Confirm ownership of relevant accounts and the process for maintaining them.

For the appointment example, compare a customer booking journey and a staff management journey separately. The simplest combined option is not always the best experience, but separate products add coordination costs. Review accessibility and the ability to support users who cannot use the preferred device. The service needs an appropriate alternative route where the context requires one.

Evaluate continuing maintenance

List the code, services and testing required for each option. Shared implementation may reduce some duplication while still needing device-specific checks. Avoid promising that one codebase means no platform-specific work. Include updates, release review, security fixes and support in the ownership model. A lower initial estimate can be misleading if routine maintenance is omitted.

Record the selected approach, alternatives and reasons. Mark which assumptions need re-evaluation if the audience or workflow changes. Agree acceptance tests on real target devices and a plan for unsupported conditions. The final proposal should explain how the choice serves the user's job and what limitations the owner is accepting.

Delivery approach checklist

  • Map devices, environment and frequency of use.
  • Specify necessary device capabilities and alternatives.
  • Test critical requirements on target configurations.
  • Define offline states, conflicts and synchronisation.
  • Compare discovery, access, distribution and updates.
  • Include accessibility and continuing maintenance.
  • Record the decision, limitations and review triggers.

Bring a workflow description and device requirements into the first planning meeting. The right delivery approach should make the job dependable and the ownership model understandable. It is a practical product decision, not a competition between labels, and it may deserve a small investigation before a full implementation is scoped.
