Mobile Development
Apps people keep on the first screen.
Mobile is a harsher environment than the web. The network drops in lifts and on trains, the operating system kills your process to reclaim memory, storage is limited, battery is visible to the user, and every release has to pass a review before anyone can install it. An app that ignores those constraints feels broken even when the code is correct.
We build applications for both platforms — usually from a single Flutter codebase, natively where a product genuinely needs it — covering everything from customer-facing apps to field tools used by staff who are offline half the day.
The parts that decide whether an app gets kept are unglamorous: how quickly it opens, whether it works with no signal, whether it drains the battery, and whether an update ever loses someone's data. Those get the attention.
The problem
Most disappointing apps are not badly designed, they are badly conditioned. They assume connectivity, so they show spinners in a basement. They assume the process stays alive, so they lose a half-completed form. They assume a recent flagship device, so they stutter on the phones most people carry.
Store review adds another dimension: a defect found after release cannot be hot-fixed the way a website can. That changes what has to be right before shipping, and it is a discipline teams coming from the web often underestimate.
Unusable without a connection
A spinner in a lift or a warehouse is the moment people stop using an app for work.
Slow cold start
If it takes several seconds to open, people stop opening it — regardless of what it does afterwards.
Lost work on interruption
A call or a low-memory kill discards a half-finished form because state was never persisted.
Store rejections late in the day
Privacy declarations, permissions and account deletion rules found at submission rather than at design time.
Our approach
We design the offline behaviour first, because retrofitting it means rewriting the data layer. That means deciding what is cached, what queues for later, what happens when a queued change conflicts with the server, and what the user sees while any of it is pending — including the honest case where something could not be sent.
We build against real devices, not only simulators, and we watch cold start time, memory and frame timing as the app grows. Release goes through TestFlight and the Play internal track first, with crash and performance reporting in place before the public build, so the first report of a problem comes from monitoring rather than from a review.
Store submission, signing, privacy declarations and staged rollout are part of the work. Getting an app approved is a specific skill and the first submission is where most surprises live.
Capabilities
Cross-platform development with Flutter
Native iOS and Android where the platform demands it
Offline-first data and synchronisation
Push notifications and deep linking
App Store and Play Store release management
Crash reporting and performance monitoring
Outcomes
Works offline properly
Reads from local storage, queues writes, and resolves conflicts with a rule agreed up front rather than at random.
One codebase, both platforms
Flutter where it fits, which keeps feature parity and halves the cost of every subsequent change.
Monitored from day one
Crash and performance reporting wired in before release, so problems surface before reviews do.
Release process that holds
Signing, staged rollout and store metadata handled as part of the build rather than improvised at the end.
