Software that holds its depth.
BooleanBlue designs, builds, publishes and looks after web and mobile applications for organisations that would rather know than guess.
scope.clear = truelaunch.surprises = falsehandover.documented = trueFour disciplines, one line of sight.
- 01
Mobile apps
Native iOS and Android, or a shared codebase where it genuinely saves effort. We decide that per project, with the trade-offs written down.
- 02
Web applications
Accessible, fast front ends and the services behind them, from customer portals to internal tools that people actually want to open.
- 03
UI and UX design
Flows, prototypes and design systems tested against real tasks before a line of production code is written.
- 04
Publishing and support
Store listings, review preparation, release management and maintenance after launch, so the work does not stop at version 1.0.
Take the reading before you dive.
Most software trouble is visible early if somebody looks: an unclear owner for a decision, a store policy nobody read, a data flow that crosses a border it should not. We start every engagement with a short discovery phase that measures these things and writes them down in plain English.
From there we work in short, demonstrable increments. You see working software regularly, not status reports about it. When we hand over, you receive the code, the build instructions and the reasoning, so another competent team could carry on without us.
A free tool for the nervous week before submission.
The Release Sounding checks an iOS, Android or web release against the preparation that most often delays a launch: privacy disclosures, test accounts, store assets, crash reporting and rollback plans. It runs entirely in your browser and gives you a copyable checklist.
Tell us what you are trying to move.
Whether it is a first app, a stalled rebuild or a release that keeps getting rejected, a short written description is the best place to start. We reply on working days, Monday to Friday, 09:00 to 18:00 UK time.
