One app for iPhone and Android, built once and kept running

A delivery service, a garage with a mobile detailing team, or a driver network needs push notifications, GPS, and screens that still work with patchy data. A browser tab cannot do all of that well, and forcing it usually frustrates the customers you are trying to keep. An app can also stay logged in and keep working for a few seconds after the signal drops, which a mobile browser rarely manages.

7Speed Delivery is our proof of this. It is a Flutter app connected to a Firebase backend, live on both the App Store and Google Play, tracking orders and notifying drivers and customers in real time. Every order status change fires a notification instead of leaving a customer refreshing a page.

Before we write a line of code, we ask what job the app has to do on day one. Tracking an order, taking a payment, and telling both sides what happened beats a long list of features nobody asked for.

We start by mapping the people who will use it: customer, driver, garage staff, admin. We build the one path that matters most first, request, assign, track, done, before spending time on screens that only get opened once a month. Secondary screens, settings, history, help, come once the core loop is proven.

We use Flutter because it lets us build for iPhone and Android from one codebase, which keeps your app affordable to maintain. Where you need a custom backend instead of Firebase, we build that too, matched to how your business actually runs.

Getting into the App Store and Google Play involves screenshots, privacy policies, and review checklists that catch people out the Friday night before launch. We handle that part so your release date does not slip over paperwork. Apple and Google both reject apps for small formatting mistakes, so we submit early and leave room for a second review round.

Data is not always fast outside Kingston and Montego Bay. We design for weak signal: screens that keep working when a Digicel or Flow connection drops, and clear messages instead of a spinner that never finishes.

Payments need to match how customers actually pay, which in Jamaica often means cash on delivery sitting next to a card option, not a checkout copied from a US app. We build for that mix instead of assuming everyone owns a credit card.

Support runs through WhatsApp, the same place your team already talks. You should never need to learn a new tool just to ask us why a driver’s app will not update.

We will not promise a full marketplace app in two weeks. Anything with drivers, background checks, or a regulated category needs an honest timeline, and we would rather say that up front than miss a deadline later.

If all you need is an online booking calendar and a deposit, a booking add-on on your website may solve it for far less than an app. Apps cost real money to keep healthy, and we only recommend one when daily use justifies it.

Look at 7Speed Delivery on either app store, then talk to us about your own business. Datamadeclear shows we can also build a complex product for a browser when an app store is the wrong home for it.

Phones update, payment providers change their rules, and a customer always finds a way to break a screen you never tested. A mobile retainer covers watching for crashes, fixing what breaks, and keeping the app working through iOS and Android updates.

Bigger requests, a new driver role or a delivery zone for a new parish, get scoped and quoted on their own. That way you always know if you are paying to keep the app healthy or paying for something genuinely new. We send a short monthly note listing crashes fixed, updates applied, and anything on the horizon.

If you are still testing demand, start with a landing page and a WhatsApp broadcast list. Once your daily orders justify an app icon on someone’s home screen, message us and we will scope it properly.
