FAQ

Questions we hear

Straight answers to what people ask before they hire us.

Web app, mobile app or both?
It depends on how your users work. We help you pick on the free call, and many products start with one and add the other.
Do we need AI in our app?
Only where it helps. We suggest AI features when they save time or money, and skip them when they don't.
Can you take over an app someone else built?
Yes. We review the code first, then fix and grow it with a clear plan.
How does pricing work?
Every project is different, so we price it to your spec. Book a free call, and we send a custom proposal with a clear price.
Do you work in our time zone?
For US clients we commit to 4 hours of overlap with US business hours. We agree the meeting times at the start.
Do we own the code and data?
Yes. Your code, accounts, keys and data stay under your control. Nothing is shared across clients.
