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 do I choose between local developers?
Check real shipped work, ask who will write the code and get a written scope before paying. Our shortlist of Palm Beach County developers explains the criteria.
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 Palm Beach County 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 Palm Beach County 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. Palm Beach County businesses with an app that stalled or a developer who left can start with an audit before committing to a larger build.
