Mobile App Development for businesses in Tampa Bay
We build mobile apps end-to-end: the app itself, the API behind it, the admin dashboard your team uses to run it, and the App Store and Google Play submission that gets it in front of users. We're a Tampa team, so kickoff can happen across a table, and we're senior engineers, so the people you plan with are the people who ship.
Recent work includes Liftva, an iPhone strength-training app with a progression engine, Live Activity rest timer, and an AI coach; Weddings Guestbook, an offline-first iPad app with Apple Pencil handwriting, voice notes, and a photo booth; and Date Vibes, a React Native app backed by a vector recommendation engine. We choose native Swift when the app leans on platform features and React Native when one codebase across iOS and Android is the smarter investment.
Every project starts with a short paid discovery that ends in a fixed-fee estimate. You own the App Store listing, the code, and the backend from day one.

Mobile apps built to survive the App Store — and the first 10,000 users
We've launched consumer apps, field tools, and event apps. Each one shipped with the backend, analytics, and admin tooling needed to actually operate it after launch day.
Native iOS Apps (Swift)
SwiftUI apps that use the platform fully: Live Activities, widgets, HealthKit, Apple Pencil, offline storage.
Cross-platform (React Native / Expo)
One codebase for iOS and Android when speed and shared logic matter more than deep platform features.
Backend APIs & Admin Dashboards
The NestJS or Node API behind the app plus the web dashboard your team uses to manage users and content.
Offline-first & Sync
Apps that work with no signal — at a venue, in the field, on a job site — and sync when connectivity returns.
Payments & Subscriptions
In-app purchases, StoreKit subscriptions, and Stripe for cases where the app can sell outside the store.
Push, Notifications & Real-time
Push campaigns, live status updates, and real-time features that keep users coming back.
AI Features in Mobile
On-device and cloud AI — coaching, recommendations, transcription — designed for mobile latency and cost.
App Store & Play Launch
Listing, screenshots, review guidelines, TestFlight beta, and a launch plan that avoids rejection surprises.
Who's building mobile apps in Tampa Bay
Founders, consumer brands, and service companies — usually with a product that needs to live in someone's pocket.
Founders launching a consumer app
Pain
You've validated the idea but every quote is either offshore and vague or a six-figure enterprise build.
Solution
A fixed-fee MVP with a senior team, launched to the App Store with analytics and a backend you can grow on.
Service businesses with crews in the field
Pain
Techs report from the truck by text and photo, and the office re-enters it into scheduling and invoicing.
Solution
A field app for jobs, photos, checklists, and signatures that syncs straight into your operations system — offline-capable.
Events, venues & hospitality
Pain
Check-ins, guest experiences, and staff coordination happen on paper and group chats, and venue wifi is unreliable.
Solution
Offline-first apps for check-in, guest interaction, and live status — we've shipped iPad and mobile apps for exactly this.
Products that need a companion app
Pain
Your web product works, but customers want it on their phone and a wrapped website isn't good enough.
Solution
A real native or React Native app that shares your API, adds push and offline, and feels like it belongs on the device.
Built for ownership, scalability, and the long haul
Apps that make it through review and keep users after week one.
Whole product, not just the app
API, admin, analytics, and launch handled together — so there's no gap between the app and running it.
Performance you can feel
Cold-start, scroll, and sync are measured and tuned. Users notice speed before features.
Local and accountable
A team you can meet in person in Tampa. No offshore hand-offs, no account managers between you and the engineers.
Opinionated, but not married to a stack
We default to a tight set of tools we trust in production, and pick the right one for each layer.

Questions about mobile app development in Tampa
What Tampa Bay businesses usually ask before kicking off a project with us.
Still unsure what you need?
Book a 30-minute technical discovery call. We'll help you clarify scope and the right next step.
Should we build native or React Native?
Native Swift when the app leans on platform features — Live Activities, Apple Pencil, HealthKit, heavy offline work — or when iOS is the only target for now. React Native (with Expo) when you need iOS and Android from one codebase and the app is mostly screens, data, and API calls. We'll recommend one during discovery and explain the trade-off in plain terms.
How much does it cost to build an app in Tampa?
Scope drives it. A focused MVP with a backend is typically a low-to-mid five-figure project; apps with real-time features, payments, and multi-platform support are more. We produce a fixed-fee estimate after a short paid discovery, and you keep that document either way.
How long until we're in the App Store?
Most MVPs reach TestFlight beta in 8–12 weeks and the App Store shortly after. We handle the listing, review guidelines, and resubmissions if Apple pushes back.
Do you build the backend and admin tools too?
Yes, and we recommend it. An app without an API, an admin dashboard, and analytics is a demo. We ship all three so you can operate the product after launch.
Will the app work without internet?
If it needs to. We've shipped offline-first apps for venues and events where wifi can't be trusted — local storage, conflict-safe sync, and background upload when the connection returns.
Who owns the App Store account and the code?
You do. The app is published under your Apple Developer and Google Play accounts, the code lives in your GitHub organization, and we assign all IP on delivery.
