FAQs
Frequently asked questions.
Anything else about Product Engineering? Ask us directly. A real engineer reads every message.
What does a product engineering company do?
It plans, designs, builds, tests, launches and maintains digital products such as mobile apps, web platforms and SaaS products, usually with one team covering every stage.
How long does it take to build an app or web platform?
A focused first version typically takes three to five months for mobile apps and two to four months for web platforms. We give a firm timeline after discovery.
How much does product development cost?
It depends on features, platforms and integrations. After a short discovery we share a clear estimate with options to fit your budget.
Should we build native or cross-platform apps?
Cross-platform (Flutter or React Native) suits most apps and saves budget. We recommend native when an app needs very specific device features or top performance.
Who owns the code and designs?
You do. All source code, designs and documentation are assigned to you under contract.
Can you take over a product another team built?
Yes. We review the code and documentation first, then agree a plan to fix, finish or improve it.
Do you support products after launch?
Yes. We offer monitoring, bug fixes, OS updates and new features as an ongoing service.
