Mobile Apps in London
Field software is judged by the person holding the phone, in the worst ten minutes of their day. Steel-framed buildings, loading bays and rural stretches of road all kill signal, which is why offline working is the baseline here rather than a feature.
Do you build mobile apps for businesses in London?
Yes. GTX Digital builds iOS and Android apps for field teams, drivers and engineers working out of London, including offline-first apps that complete a full job with no signal at all.
- Offline-first: the full job completes with no connection at all.
- Conflict-safe sync, so two devices cannot silently overwrite each other.
- Designed for one-handed use on a device that is not yours.

Head offices and professional services, served from the Triangle
London work reaches us when the brief is well defined and the client wants senior delivery without London rates. Vague, exploratory work is better served by somebody who can be in the room every day.
London is outside the Golden Triangle, and we are straightforward about that: we are a Midlands business working with London clients rather than a London agency. What that buys you is Midlands delivery economics with genuine seniority on the work, and what it costs is that we are not twenty minutes away.
For this work that lands mainly in Property & construction, Financial & professional services and Corporate head offices.

How we work here
What mobile apps looks like in London.
The full scope, phases and deliverables are on the Mobile Apps service page. These are the parts that are specific to working here.
-
Offline is the default
The device holds the working set and the whole job completes in flight mode. Sync is queued, retrying and conflict-aware.
-
Designed for gloves and vans
Fewer taps than the paper it replaces, usable one-handed, on a shared device that logs out overnight.
-
Evidence captured once
Photos, signatures, scans and timestamps taken at the point of work, so the rekeying step at the depot disappears.
-
Piloted before rollout
A small group of real users for two to three weeks, and their feedback decides whether it ships.
-
On site in London
London is a direct train for us from several points in the Triangle, so a scheduled on-site day is straightforward even though we are not local. Discovery and the sessions that decide a design happen in person; delivery then runs remotely with scheduled reviews, and there is no travel charge inside the Golden Triangle.
Questions
Mobile Apps in London, answered.
The questions businesses in London ask before they commission this work.
Will an app work in the warehouses and on the roads around London?
That is precisely what we design for. Large distribution sheds, basements and rural stretches all lose signal, so we build offline-first: the full job completes on the device and syncs when coverage returns, tested in genuinely bad conditions rather than in a meeting room. We spend a day doing the job before designing anything.
