When device APIs, performance or store rules need it
Services
Mobile development
Native, cross-platform or a PWA. UX, engineering, QA and store or web release in one UK IT team.
Build
The stack follows the brief
SJ Technologies designs and builds mobile apps for iOS, Android and the web when a PWA is the better fit. Native or cross-platform is a design choice we make from the devices, the offline needs, the integrations and who will maintain it.
We do not start from a favourite framework. If one codebase is the honest trade-off, we say so and we build that. If native APIs, performance or store rules need a native app, we build native.
Designers, developers and QA sit on the same product. Store or web release is part of the same job, against a written scope.
When one codebase is the honest trade-off
When a store listing is not required, or the browser is the product
UX, engineering, QA and release, with source that remains yours
How a mobile product is delivered
The same people take the app from the brief to the store, or to a home screen, without a chain of subcontractors.
iOS and Android
Native apps where the product needs them, including iPhone, iPad and phone-sized Android.
Read moreCross-platform
Flutter, React Native or similar, only where the trade-offs are acceptable.
Read moreProgressive web apps
Installable sites that work on a phone without a store listing, when that is the shorter path.
Read moreQA and release
Tests against the scope, then App Store, Play or a web release the client can stand behind.
What you get
Named people on the mobile product
You will know who owns design, engineering and go-live. Changes of personnel are told to you in writing.
Native, cross-platform or PWA, chosen from the requirement. UX, engineering, QA and store or web release in one IT team. The stack is a decision in the brief, not a package we sell first. Source, certificates and store accounts remain yours under the contract.
