How the work
is shaped.

Three ways in, depending on how settled the idea already is. All three are priced as a fixed number agreed in writing before anything is built — there is no hourly rate here, because an hourly rate makes my slowness your problem.

User flows for the journey that actually matters
A clickable prototype with real content, not lorem

No production code
No store submission

Release management and store review handling for each version

How pricing works

Fixed, not hourly

You know the number first

The scope and the cost are agreed in writing before work starts. If I estimate badly, that is mine to absorb — which is the correct incentive for the person doing the estimating.

Paid in three

Nothing paid for work not done

A third to book the slot, a third when design is signed off, a third on handover. A retainer is invoiced monthly in advance.

Change is normal

Scope changes are re-quoted, not absorbed quietly

Products change while you build them. When yours does, you get a written number for the change before it happens — never a surprise line on an invoice.

What you own

All of it,
on delivery.

Source code, repositories, developer accounts, design files and the design system transfer to you at handover. Nothing is held back as leverage for a maintenance contract, and there is no proprietary layer you would have to licence to keep the product running.

Source & repositories: Yours
Apple & Play accounts: Registered to you from day one
Design files: Yours, with the system documented
Ongoing licence fees: None

When this is the wrong studio

Said plainly,
before you pay.

Two engagements at a time means saying no often. It is fairer to say what gets a no here than to let you find out in week three.

Staff augmentation

If what you need is a pair of hands inside someone else's process and someone else's design, an agency bench serves you better than this does.

A deadline that is already gone

Six weeks of work does not fit into three. A date that has already passed its own scope is a conversation for before the contract, not after.

Design as decoration

If the interface is meant to be applied at the end to something already built and already decided, the part of this that is worth paying for is already over.

Still the right shape?

Send a short brief — what it is, who it is for, and roughly when. It is read by the person who would do the work, and answered personally within 48 hours.
