What we do
App development, from prototype to store
An app gets expensive when it starts wrong. GHP designs the screens before writing code, you approve by clicking through them, and only then development starts. The same product ships to phone and browser.

Frequent questions
How much does a project cost?
It depends on the size. We do not sell fixed packages or charge per page. After the first conversation you get in writing what will be done and what it costs, and you decide with no obligation.
How long does it take?
The timeline comes with the plan. Because delivery happens in parts, you do not wait until the end to see something working.
Do you maintain it after delivery?
Yes. Once the project is live, maintenance continues with the same team that built it. Nothing is thrown over the wall.
