These are independent organizations; listing them is not an endorsement or a partnership claim. Confirm details with each one before you apply.

Questions
Frequently Asked Questions
Is App369 based in Boynton Beach?
No. App369 LLC is based in Miami, at 1000 Biscayne Blvd, Miami, FL 33132. It serves Boynton Beach businesses remotely on Eastern Time and has no Boynton Beach office.
Can we meet in person in Boynton Beach?
No. App369 works remotely and asynchronously from Miami, with written updates and shared progress builds. There are no standing meetings; live calls are available at $100 per 15 minutes.
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.
