Questions
Frequently Asked Questions
What does App369 build for Boca Raton businesses?
iOS and Android apps, web apps and customer portals, backends and APIs, internal tools that replace spreadsheets, AI features such as assistants and document extraction, and Stripe or Shopify integrations. Simon also takes over and fixes apps that another developer or an AI builder started.
How much does an app developer in Boca Raton cost with App369?
It depends on the offer: fixed-price offers have published prices, shown on this page and paid in full before work starts. Mobile and web app starting prices are on the fee structure page. Larger builds start with a paid scoping and are quoted in writing.
Is App369 a Boca Raton app developer?
App369 is based in Miami, about 50 minutes from Boca Raton (approximate), not in Boca itself. We have no Boca Raton office. We serve Boca clients remotely on Eastern Time.
Can we meet in person in Boca Raton?
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.
I'm an FAU student or researcher with an idea. Where should I start?
Talk to The Runway at FAU and the Florida SBDC at FAU first, since both are free or university-backed. Once you know what the first version must do, a fixed-price offer from $450 can cover a small, well-defined piece. See the Palm Beach County resources guide for the full list.
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 Boca Raton 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 App369 offers maintenance that covers bug fixes, iOS and Android OS updates, security patches, dependency upgrades and small feature work, so your Boca Raton app keeps working as the platforms change.
Can you work with existing projects?
Yes. Simon takes over existing codebases, especially Flutter and Firebase apps, for code audits, bug fixes, new features and migrations. Boca Raton businesses with an app that stalled or a developer who left can start with an audit before committing to a larger build.
