Questions
Frequently Asked Questions
Can we meet in person in Lake Worth 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.
Does the name change from Lake Worth affect my business listing or SEO?
It can. The city became Lake Worth Beach after a 2019 vote, so check that your Google Business Profile, directory listings and website use a consistent name and address. We can help with that when we rebuild your website.
What does a first project usually look like?
Most small businesses start with one piece, such as a booking page, a quote form or a cleaned-up website. Fixed-price offers start at $450 and are listed on our fixed-price page.
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 Lake Worth 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 Lake Worth 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. Lake Worth Beach businesses with an app that stalled or a developer who left can start with an audit before committing to a larger build.
