Mobile apps for Saint Barthélemy businesses and their guests

The day before an arrival, a villa manager juggles cleaning, the pool, the grocery delivery and the hire car. A simple app puts each task in front of the right person. Your guests can send their requests too, without a long thread of messages.

Four plans, depending on what your customers need to do

  • Essential App

    A simple app to present your business, with the essential features. On one type of phone: iPhone or Android, your choice. For both, see the Pro App.

    Timeline: 10 to 15 days

    From €6,500

  • Pro AppOur pick

    Your customers create an account and always see your up-to-date information. Your messages appear on their phone screen, such as offers, reminders or news. On iPhone and Android.

    Timeline: 15 to 20 days

    From €11,000

  • Business App

    Your customers have their account, receive your messages and pay directly in the app, without leaving it. On iPhone and Android.

    Timeline: 20 to 30 days

    From €18,000

  • Custom App

    For large projects: a platform where several sellers offer their products, with live tracking. Everyone has their own access, and you manage everything from a complete back office.

    Timeline: 30 days or more

    From €35,000

Starting prices, excluding taxes (any taxes depend on your country or territory and your situation; the quote specifies them), in euros. After a free 20-minute call, you receive a written quote within 48 hours.

You pay in three stages, as the project progresses, never everything upfront

  • 30% at the start

    The project begins: we design the screens of your app and set the schedule with you.

  • 40% when you approve the test version

    You test the app on your own phone before it is published.

  • 30% on delivery

    Your app is live on the App Store (iPhone) and Google Play (Android). We hand over its source code, the files that make it work.

App ideas for St Barts businesses

  • A guest app for a concierge service

    Guests follow their requests, from the private chef to the boat trip, and receive a confirmation on their screen. You see every request in one place.

  • Taxi or car handover app

    The driver sees the flight or ferry time and the handover point, at the airport or the Gustavia ferry terminal. Guests know exactly where to go when they arrive.

  • Staff app for villa arrivals

    Housekeepers and pool technicians tick off their tasks and add a photo before guests arrive. You check each villa from your phone.

How the project runs

Frequently asked questions

How long does an app take?
Most apps take 10 to 30 days. The written quote, sent within 48 hours of the free call, gives the planned delivery date.
Can my guests use the app before they land?
Yes, once they have downloaded it. With the Pro App, your messages appear on their phone screen: handy for sending arrival details before they land.
Can you build a concierge app for my clients?
Yes. Accounts, requests and messages suit a concierge app well. We start from how your service works today and suggest the right plan during the free call.
Will the app work for guests from abroad?
It runs on iPhone and Android, wherever your guests live. If they pay in the app, we study the payment methods with you.
iPhone, Android, or both?
The Essential App works on one of the two, your choice. From the Pro App, it works on iPhone and Android: we build it once for both, which lowers the price and the timeline.
Who puts the app on the App Store and Google Play?
We do. It is published on Apple and Google accounts opened in your name, so that it stays yours. The registration fees charged by Apple and Google are paid by you: we state them in the quote.
Does the app belong to me?
Yes. Once the project is paid in full, the app is yours, with its content and its source code.
What happens after delivery?
The first month of support is included. After that, a monthly plan covers the updates required by Apple and Google, security and backups. The Business plan also includes up to 5 hours of changes per month (texts, prices, photos…).
