Local context
Delray Beach business context
Delray Beach's downtown is a small-business economy. The Downtown Development Authority reports that 95% of shops on Atlantic Avenue are small businesses, which makes rent and operating costs a live concern for owners. That favors lean, fixed-scope software over large custom builds.

Questions
Frequently Asked Questions
What does App369 build for Delray Beach 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 Delray Beach 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.
How far is App369 from Delray Beach?
App369 is based in Miami, about 55 minutes from Delray Beach by car (approximate). We have no Delray Beach office.
Can we meet in person in Delray 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.
I'm a small shop on Atlantic Avenue. What is a realistic first project?
Most small businesses should start with one thing: a booking page, an ordering flow, or a cleaned-up website. Our fixed-price offers start at $450 and are listed on the fixed-price page, so you know the cost before work starts.
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 Delray 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 App369 offers maintenance that covers bug fixes, iOS and Android OS updates, security patches, dependency upgrades and small feature work, so your Delray Beach 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. Delray Beach businesses with an app that stalled or a developer who left can start with an audit before committing to a larger build.
