Frequently Asked Questions
Is App369 really based in Boynton Beach?
Yes. App369 LLC was filed in Florida on November 8, 2021 and is based at 8225 Emerald Winds Circle, Boynton Beach, FL 33473. It is a home-based, founder-led studio, not a storefront or a large office.
Can we meet in person in Boynton Beach?
Usually, yes, by arrangement. App369 works remotely and asynchronously from Boynton Beach, with written updates and shared progress builds. In-person meetings anywhere in Palm Beach County are possible by arrangement; ask when you contact us.
How long does a typical project take?
It depends on scope. As a rough guide, a marketing website takes 4-8 weeks, a web application 2-4 months, and a mobile app 3-6 months. Every Boynton Beach project starts with a written scope and milestone plan, so you know the timeline before any build work starts.
Do you provide ongoing support?
Yes. After launch we offer maintenance that covers bug fixes, iOS and Android OS updates, security patches, dependency upgrades and small feature work, so your Boynton Beach app keeps working as the platforms change.
What's your pricing model?
App369 uses project-based pricing with a 50/50 payment structure: 50% upfront and 50% on completion. Current ranges are published on our fee structure page, and smaller fixed-price packages are available for well-defined work.
Can you work with existing projects?
Yes. We take over existing codebases, especially Flutter and Firebase apps, for code audits, bug fixes, new features and migrations. Boynton Beach businesses with an app that stalled or a developer who left can start with an audit before committing to a larger build.
