Responsive browser experience
Design a coherent application experience across desktop and mobile browsers from one web foundation.
What you receive
Responsive screens and browser compatibility plan.
App Development
Progressive Web Apps
We help companies give users an accessible, app-like experience through the browser. Our engineers build responsive journeys that work across devices and fit the product’s performance and connectivity needs.
Tranz / Engineering in practiceWhat we can help with
Applications built around complete user journeys
A useful application connects the screen people see with the services and information behind it. We map the main journeys, integration boundaries and device constraints before choosing a web, mobile or browser-based approach.
Install and offline behaviour
Define which journeys benefit from installation or caching and communicate clearly when data is unavailable.
What you receive
App manifest, cache rules and offline states.
Updates and synchronisation
Plan how new versions reach users and how queued actions recover when connectivity returns.
What you receive
Update strategy, sync rules and connectivity tests.
Where it helps
Start with a real task, then shape the solution
These are examples of workflows we can scope with your team.
Customer self-service
Let customers register, manage information, submit requests and follow progress without repeated calls or manual updates.
Field and internal tools
Give teams access to assigned work, customer records and task updates where they need them.
Connected product platforms
Bring account access, dashboards, notifications and operational workflows into one coherent experience.
A concrete scope
Know what the engagement will produce
We agree on the deliverables for your project before delivery begins.
A defined scope
Prioritised workflows, dependencies, responsibilities and acceptance criteria for the agreed release.
Reviewable work
Responsive screens and browser compatibility plan; App manifest, cache rules and offline states; Update strategy, sync rules and connectivity tests.
A practical handover
The documentation, configuration, operating guidance and team walkthroughs included in your delivery plan.
Frameworks & tools
A toolkit shaped around your requirements
These are technology options for the engagement. We choose the stack around your existing systems, deployment needs and team; each project uses a relevant subset.

SentryHow we work
Move from a clear brief to a useful release
Map the journeys
Identify users, key actions, device needs and the smallest useful first release.
Design the experience
Prototype navigation, forms, loading states and error recovery before building the screens.
Build and connect
Develop the interface and services in reviewable increments, with testing across important journeys.
Launch and improve
Prepare deployment or store submission, hand over the application and prioritise improvements from usage.

Before we begin
Questions about the engagement
Should we build a web app or a mobile app?
We look at how often people use the product, the devices they carry, distribution needs and requirements such as offline access or device features. The choice follows those needs.
Can you connect the app to our current systems?
We review API availability, authentication, data ownership and rate limits. Where an API is missing, we scope the integration work before committing to the release.
Can we launch a smaller first version?
Yes. We define a complete core journey for the first release and separate later features, while keeping the data model and integration decisions ready for expansion.
