Ways to work together
Pick the engagement that fits your stage.
Fixed-scope project
Clear deliverables, a fixed price and a delivery date. Best when you know what you need built.
Monthly retainer
A reserved block of hours every month for ongoing design, development or content.
Hourly consulting
Architecture reviews, audits and pair sessions when you need expert eyes, not a full build.
Every engagement starts with a free 30-minute call and a written quote — no commitment until you approve the scope.
Questions
Answers before you ask.
Native or cross-platform?
Cross-platform covers most products at a fraction of the cost. We go native for specific modules when performance or hardware access demands it.
Do you publish the app for us?
Yes. We prepare the listings, handle review feedback and release under your developer accounts so you keep ownership.
Can the app share a backend with our website?
Absolutely. We design APIs so web and mobile stay in sync from a single source of truth.
What about updates after launch?
Over-the-air updates for small fixes and store releases for bigger changes, on a schedule we agree together.
