The Problem

Your tools are
holding you back.

Before

You're managing everything through WhatsApp, spreadsheets, and five different apps that don't talk to each other.

Clients can't book, pay, or interact with you in one place — so they message you for every basic thing.

You look smaller than you actually are. No branded platform, no professional presence — your personal brand isn't coming through.

After

One custom app built exactly around how your business works — not how someone else's does.

Bookings, payments, and notifications all in one place, under your brand, on your terms.

A branded app in your clients' pockets — that makes your personal brand stand out and positions you as the real deal.

The Process

Simple process.
Serious results.

01
Discovery Call

We talk about your business, your brand, and what the app needs to do. No technical knowledge required — just tell me how your business works and what's frustrating you right now.

02
Design & Build

I design and build your app using FlutterFlow and Firebase. You get regular updates, you can share feedback, and nothing gets built that you haven't approved.

03
Launch & Maintain

Your app goes live on the App Store and Play Store. I handle the full submission — and keep everything running with updates and fixes every month after.

What I Build

Every app is custom.
Every project starts
with your problem.

I don't use templates or recycle old projects. Every app starts from scratch — designed around your business, your brand, and the problem you need to solve. Your app, your identity.

📅
Booking & Scheduling Apps

Custom booking flows, availability management, calendar sync, and automated reminders. For coaches, consultants, studios, clinics — anyone whose business runs on appointments.

💳
Payment & Subscription Apps

Stripe-integrated apps with one-time payments, recurring subscriptions, and membership tiers. Your clients pay in-app, automatically, without chasing invoices.

👥
Client & Community Apps

Client portals, progress tracking, in-app messaging, and push notifications. Keep your clients engaged, informed, and loyal — all inside your branded app.

🏢
Internal Business Tools

Admin dashboards, team management, and internal apps that replace spreadsheets and manual work. If your team is wasting time on repetitive tasks, there's a better way.

Who Builds Your App

You work directly
with me. No middlemen.

I'm Samu — a Belgian developer specialized in building mobile apps with FlutterFlow and Firebase.

I started Samu Studio because I saw too many entrepreneurs stuck with generic tools that weren't built for their business. Spreadsheets, WhatsApp groups, five different subscriptions — when a single well-built app would solve everything.

A custom app isn't just a tool. It's a statement about who you are. It strengthens your personal brand, sets you apart from the competition, and gives your clients a reason to stay loyal.

Every project I take on is built by me personally. You have my number. You get real updates. And I don't sign off until you're genuinely happy with what we've built.
