Apps
iOS, Android, Apple Watch. For customers, or for a technician with one hand free and no signal.
We're The Bad Lemon. Field apps, dashboards, booking systems, consumer apps, watch apps. You bring the need; we own it from there: an MVP that proves it with real users, then a product built to run for years.
iOS, Android, Apple Watch. For customers, or for a technician with one hand free and no signal.
Booking and workflow systems where every job has a state, and each role sees its own work. Backend included.
Your tool works, your team still works around it. We fix the flow that's bleeding and leave the rest alone.
Send us the flow that hurts. We'll tell you what we'd fix, and what we'd leave alone.
Design and build, same team. Energy, agritech, field services, publishing, fitness so far. Sector doesn't matter. Use does.


Stakeholders, the people doing the work, the workflow as it really runs. Including the forks nobody put on the flowchart.

The smallest version that proves it with real users. On TestFlight and Play, not on a slide.

States, roles, integrations, dashboards. Built for the edge cases the MVP was allowed to skip.


Retainer support while it meets the real world.
We build our own products too. Same rules as client work: one hand, no account, no excuses. If it doesn't work mid-run, it doesn't ship.
A free, anonymous map of places that felt unsafe. Check it before a run, pin it for the next person. The crowd keeps it honest.
New, used and second-hand prices for the exact edition, across Europe's bookshops and marketplaces. Nobody pays to rank.
One tap on your wrist saves exactly where you are. Find it later on your phone, share it with a link.
Record from your wrist with no phone in sight. Transcribed on device, shared wherever you need it.
Paste icon code, watch it render live, drop the SVG on your canvas.
You may wonder why we're that bad. Because saying yes to every idea is easy. Telling you which feature nobody will ever tap, then building the one they will? That's the job.
Why we're different
Mobile apps (iOS and Android), Apple Watch apps, web dashboards, booking and workflow systems, CRMs, automations, and the backend that holds them together. Design and development, same team.
Both. Half the time the fix is a rebuild of one flow. The other half it's an app, system or dashboard that didn't exist yet.
Established companies with a service to run and people who depend on the tools. Any sector. We don't take early-stage startups.
Retainers. We scope from a diagnosis and price the phase in front of us, not a guess at the whole roadmap.
Flutter and Expo for cross-platform apps, Swift for Apple Watch, React/Next.js and Postgres for dashboards and platforms. Chosen per project, not per fashion.
