**Best app development company in Miami: four firms with a Miami address, plus App369, compared on Clutch data, timelines and proof of work, checked Oct 22, 2026.**
**Disclosure:** App369 publishes this guide and is one of the five companies listed. It compares what each company publishes on its own website and its public Clutch profile, checked on October 22, 2026. It is not an independent benchmark.
## Key takeaways
- →App369 publishes this guide and is one of the options. It is based on public information, not an independent benchmark.
- →Four app development companies show a Miami street address on their own website: Foonkie Monkey, Leenspace, SpaceDev and Synergy Labs. App369 is also based in Miami.
- →None of the four Miami firms publishes a project price. Clutch minimums run from $10,000+ (Leenspace) to $25,000+ (the other three).
- →All four have Clutch ratings of 4.9 or 5.0, from 12 reviews (Leenspace) to 56 (Foonkie Monkey).
- →Foonkie Monkey, Leenspace and SpaceDev list Latin American offices or clients. Ask where the developers on your project will sit.
- →Leenspace and SpaceDev list the same street address, and Synergy Labs' Clutch profile lists Hollywood, Florida, as its headquarters. A Miami address is not always a large local office.

## What a Miami app development company is (and isn’t)
An app development company designs, builds and launches mobile or web apps: the screens, the database, sign-in, payments and the store listings. In this guide, a Miami company is one that shows a Miami street address on its own website. Many firms that appear in Miami searches list Miami only as a city they serve, or show a Miami address on a directory but not on their own site. This guide leaves those out, along with website and marketing studios with no app work. For the rest of South Florida, see the [Palm Beach County](https://app369.com/blog/best-app-developers-palm-beach-county-2026/), [Boca Raton](https://app369.com/blog/best-app-development-company-boca-raton-florida-2026/) and [Delray Beach](https://app369.com/blog/best-app-development-company-delray-beach-florida-2026/) guides, and for Central Florida the [Orlando](https://app369.com/blog/best-app-development-company-orlando-florida-2026/) guide.
## How I compared these Miami developers
I checked each company’s own website and Clutch profile on October 22, 2026:
- **Address:** a Miami street address on the company’s own site, not only on a directory.
- **Published price or timeline:** a project price, minimum or timeline on the company’s own site.
- **Clutch data:** minimum project, hourly rate, rating and review count, read the same day.
- **Proof of work:** named clients and case studies with their own pages.
- **Where the team works:** offices and staff locations stated on the site or on Clutch.
I didn’t hire these companies or test their apps. Companies are listed alphabetically. The order is not a ranking.
## The best app development companies in Miami in 2026
### 1. App369, best for founders whose AI-built app needs fixing before launch
App369 publishes this guide. It is one developer, Simon Dziak, in Miami. Its [AI-Built App Rescue](https://app369.com/fixed-price/ai-app-rescue/) is for apps made with Lovable, Bolt, Cursor, Replit, v0 or Claude Code that work in the demo and break with real users. A $450 Launch Check reviews sign-in, data access, payments and deploys within 3 business days of read-only access. It ranks each issue and ends with a fixed price for a Rescue Sprint: up to 5 critical or high issues fixed in 7 business days, $1,950, or $1,500 after the $450 credit. It works on React, Next.js or Vite apps on Supabase or Firebase with Stripe. For a new build, web apps start from $6,000 and mobile apps from $9,000.
- **Strengths:** the only published project prices here; you work directly with the developer; you keep the code and get a written report even if you fix it elsewhere.
- **Limitation:** one developer, so no large team.
- **Best for:** founders and small businesses with a working prototype that has to hold up for real users.
Services and fixed prices for Miami and South Florida businesses are on the [App369 Miami page](https://app369.com/locations/miami-florida/).
### 2. Foonkie Monkey, best for banks, fintechs and healthcare companies
Foonkie Monkey shows a Miami office at 990 Biscayne Boulevard, Suite 501, in the footer of its site, alongside offices in Bogotá, Colombia, and Harpenden in the UK. It builds apps for regulated industries and lists HIPAA, GDPR, PCI-DSS, SOC 2 and ISO 27001 compliance work. Its portfolio includes banking apps for Bancolombia and Davivienda, the latter with the agency Leo Burnett, and fintech apps for Payout and Quick Penny. On Clutch it lists a $25,000+ minimum project and $25–$49 per hour, with a 4.9 rating from 56 reviews, 50–249 employees and its founding in 2010 (read October 22, 2026).
- **Strengths:** the most Clutch reviews among the Miami firms; named bank apps; compliance coverage for health and finance.
- **Limitation:** no published price, and its site is on a UK domain with offices in three countries, so ask which office runs your project.
- **Best for:** banks, fintechs and healthcare companies in Miami or Latin America that need a compliance-aware app.
### 3. Leenspace, best for Flutter apps for Latin American markets on a modest budget
Leenspace shows its address at 25 SW 9th Street in Miami on its contact page. It builds Flutter apps for mobile, web and desktop, moves existing apps to Flutter, and names Firebase, .NET, Azure and AWS. Its case studies include Agora Shop, which it describes as an e-commerce super app serving over 5 million users, and its site shows logos for Liberty Latin America and Evertec. On Clutch it lists a $10,000+ minimum project and $25–$49 per hour, with a 5.0 rating from 12 reviews and 10–49 employees (read October 22, 2026).
- **Strengths:** the lowest Clutch minimum here; one Flutter codebase for mobile and web; Latin American enterprise clients.
- **Limitation:** few Clutch reviews, and its mobile work centers on Flutter, so it’s a poor fit if you need separate native apps. It lists the same street address as SpaceDev.
- **Best for:** Spanish-speaking and Latin America-facing businesses that want one Flutter app at a lower rate.
### 4. SpaceDev, best for crypto, tokenization and fintech products
SpaceDev shows its office at 25 SW 9th Street, 4th Floor, in Miami, on its contact page, plus offices in Montevideo and Buenos Aires. It builds blockchain products such as smart contracts, tokenization and on-chain compliance, plus web and mobile apps and security audits, and shows ISO 27001 and SOC 2 badges. Its case studies include Collector Crypt, which tokenizes graded trading cards, Byrrgis, a non-custodial broker, and Zenda, a currency exchange in Uruguay. Its site says most MVPs are production-ready in 8–12 weeks. On Clutch it lists a $25,000+ minimum project and $50–$99 per hour, with a 5.0 rating from 53 reviews and 50–249 employees (read October 22, 2026).
- **Strengths:** a perfect Clutch rating across 53 reviews; deep crypto and security-audit work; a published MVP timeline.
- **Limitation:** Clutch tags only about 10% of its work as mobile apps, so it suits a fintech product more than a typical consumer app.
- **Best for:** fintech, crypto and Web3 founders who need tokenization, exchanges or compliance built in.
### 5. Synergy Labs, best for consumer and social app MVPs
Synergy Labs shows its headquarters at 78 SW 7th Street in Miami on its own site, and lists other offices including Dubai, San Francisco, New York City and Dallas. It builds mobile apps and AI features, and names Flutter, FlutterFlow, Swift, Kotlin, React Native and Firebase. Its case studies include Clapper, a social app it reports at over 1 million downloads, and Forbes Councils. Its site says apps launch in 6–8 weeks in its FAQ and 10 weeks in its headline. On Clutch it lists a $25,000+ minimum project and $50–$99 per hour, with a 4.9 rating from 45 reviews, and its Clutch profile lists Hollywood, Florida, first. Clutch’s review summary calls its delivery experiences mixed, with some clients reporting non-functional apps and poor architecture (read October 22, 2026).
- **Strengths:** named consumer apps at scale; a fast Flutter build process; a proposal within about 2 days.
- **Limitation:** mixed reviews on Clutch, and its two published timelines disagree, so put the schedule in the contract.
- **Best for:** consumer and social app startups that want a fast Flutter MVP.

## How to choose an app developer in Miami
1. **Check the address and the team.** Look for a street address on the company’s contact page, check it on [Sunbiz](https://search.sunbiz.org/), and ask where the people building your app work.
2. **Read the negative reviews too.** On Clutch, sort by lowest rating and ask the firm what changed.
3. **Get a written scope and timeline.** The [app development RFP guide](https://app369.com/blog/complete-guide-app-development-rfp-2026/) works with any firm on this list. For Miami-specific budgets, see the [Miami app development cost guide](https://app369.com/blog/miami-app-development-cost-secrets/), and for the questions to ask each firm, the [Miami app development guide](https://app369.com/blog/mobile-app-development-miami-complete-guide/).
4. **Fix before you rebuild.** If you already have an AI-built prototype, a fixed-price review usually costs less than starting over.
5. **Own everything after launch.** The [mobile app handoff checklist](https://app369.com/blog/mobile-app-handoff-checklist/) lists the code, accounts and store listings you should receive.
## Fix your app or ask a question
If your app already exists and breaks with real users, start with the [$450 AI-Built App Rescue Launch Check](https://app369.com/fixed-price/ai-app-rescue/), or [request it through the contact form](https://app369.com/contact/?offer=offer15-launch-check). For a new build or anything else, the [contact form](https://app369.com/contact/) gets you a written reply. Either way, compare it with a quote from at least one other company on this list.
