App Development FAQ
Common questions we hear in Denver
How long does app development take?
It depends on scope. Most projects are delivered in milestones so you can launch sooner and expand features over time. We start with clear requirements, then build a realistic timeline around what matters most for your first release.
Do you help with App Store and Google Play launch?
Yes. We help prepare builds, handle submission requirements, and support post launch updates. That includes guiding you through release steps, reviewing store requirements, and preparing for future versions.
Can you rebuild or improve an existing app?
Yes. We can audit and modernize an existing app, improve performance, and add features without breaking core functionality. This is a common path for teams that have outgrown an early version or inherited a hard to maintain codebase.
