Focused iOS product builds

Your first iOS build. <24 hours.

Bring the idea, workflow or rough screens. We turn a focused scope into a working iPhone experience you can put in front of users, customers or investors the next day.

The 24-hour clock starts after written scope, required assets and account access are complete. The commitment is a focused first build—not App Store approval, an unlimited feature list or a substitute for security and compliance work.

Good first-build scopes

Small enough to ship. Important enough to matter.

The best 24-hour projects have one user, one essential job and one unmistakable outcome. We narrow the idea without losing the reason it needs to exist.

01 · Founder prototype

Make the pitch tangible.

Turn a deck, workflow or rough product concept into a device-ready experience for the next investor or customer conversation.

Representative scope · 3–5 core screens
02 · Internal workflow

Move one painful process onto the phone.

Capture, approve, review or coordinate a repeatable workflow that currently lives across email, spreadsheets and memory.

Representative scope · one primary role
03 · Existing product companion

Give the product a focused mobile front door.

Package a proven web or service workflow into the moments where a customer actually needs it on iPhone.

Representative scope · defined API access
The 24-hour clock

No disappearing into a six-week discovery phase.

We do the thinking before kickoff, then keep the build deliberately narrow.

Scope it

We agree on the user, core flow, exact deliverable, price, assets and access.

Lock the brief

You approve the written build card. Changes after that become the next scope.

Build and test

One senior builder owns product decisions, implementation and device checks.

What “first build” can include

  • A focused native iOS experience
  • Core screens and one primary workflow
  • Existing API or test-data integration
  • Device-tested build and handoff notes

What needs a separate scope

  • App Store review or guaranteed approval
  • Large backends or undefined integrations
  • Regulated production launch readiness
  • Unlimited revisions or an entire roadmap
Built, not mocked

See the interaction, not another slide deck.

A few recent iPhone interaction studies. Each clip is a working build captured on-device or in a device-ready presentation.

Consumer product

Onboarding with momentum.

A branded setup flow that moves from product choice to a useful first action.

Member workflow

The next action stays obvious.

Schedules, confirmations and practice tasks organized around what matters now.

Voice workflow

Complex work becomes one clear step.

A focused mobile path from spoken input to a structured review.

Start with the actual problem

What should someone be able to do tomorrow?

Send the outcome, not a perfect specification. We will reply with the questions needed to determine whether it fits the 24-hour format and what the fixed scope should be.

A preference, not a confirmed start date.
We use these details to evaluate the request, contact you and prepare a possible written scope. No payment is collected here.
