CUSTOM APPLICATIONS
Create apps that do exactly what you need.
We design and build production-ready applications from scratch, or take your vibe-coded prototype and make it real, with AI in our process to build faster.
Website & Apps
The right app makes the hard thing easy.
A whitepaper, a deck, a spec sheet, these still have their place, but they no longer earn the buyer's time the way they once did. Buyers expect to interact, calculate, configure and explore.
A custom web app gives them that. An ROI calculator, a maturity assessment, a solution recommender, a product configurator, an interactive tool. The buyer spends more time, leaves better-qualified, and the team gets data on what they did.
Digital Apple builds custom web app development B2B for B2B brands across every industry.

AI built into how we work
We build applications the way you would expect, with one difference: AI is built into our process, and that is why our builds are faster and more affordable than a traditional developer. Our team directs every step. AI is the accelerator, the engineering and the judgement stay with us. The briefs we see most are marketing app development agency work and interactive web tool agency projects.

Make the app intelligent. We can build in an AI agent, an in-app assistant, an AI-driven workflow, an advisor at the core of the tool, so the application actively helps a user, not just responds to them. We know how, because we built our own agentic AI platform.
How it works
A creative agency, made for B2B.
We make it for you.
Custom tool development, built around your model, your buyer and your sales motion. Not a templated quiz.
We cover the full range.
ROI calculators, pricing tools, configurators, recommenders, assessments, scenario tools and interactive content.
We integrate with the stack.
CRM, marketing automation, analytics, ABM platforms, identity, payments, single sign-on, whatever the tool needs.
AI in the build.
AI in logic modelling, code acceleration and personalisation. We build AI-powered tools when the brief calls for them, with the same rigour we apply to traditional builds.
