We have set up a simple simulator that allows you to obtain a cost estimate for your project.
Answer a few questions about the specific features and requirements of your project to quickly receive an initial estimate.

What type of mobile and/or web application do you require?

We generally develop using technologies that allow us to be on all platforms.

Here are some examples of projects:
Web application only: Pairing, LFP video, MyKeurImmo, Scamac Immo, SommNinja
Web applications + mobile apps: Dentaire pro (in ReactJS + Capacitor)
Mobile apps only: Needeat, Nousdeux & LFP (in React Native).

Does your application require a login system?

What will be the main function of your mobile application?

Here are the main types of applications that can be considered:

E-commerce applications: These are platforms for selling products or services online. Examples: Amazon, Shopify.

SaaS (Software as a Service) applications: Software available via a browser, where users often pay a subscription fee to access features. Examples: Google Workspace, Salesforce.

Mobile games: entertainment-specific applications, often interactive, ranging from simple games to more complex games requiring an Internet connection. Examples: Candy Crush, PUBG Mobile.

Messaging and social media apps: platforms for communication or content sharing. Examples: Facebook, Snapchat, Slack.

Productivity applications: tools for improving time, task, or process management. Examples: Trello, Microsoft Office Mobile.

Financial and banking applications: manage bank accounts, make payments, or track expenses.
Examples: PayPal, Revolut.

Health and wellness apps: track physical or mental health, often with integrations to wearables (smart bracelets, watches). Examples: MyFitnessPal, Apple Health.

An online booking app: Kayak, Booking, Airbnb, etc. A marketplace app (such as Uber): Uber, Deliveroo, etc.

A classified ads app: Vinted, Le bon coin,

A business app: an internal company tool, a sales tracking tool, a project discussion tool, etc.

Internal messaging?

Integrating internal messaging into a web and/or mobile application is a strategic asset for improving real-time communication and collaboration between users.

This allows for centralized communication, faster decision-making, and reduced dependence on external platforms.

Internal messaging also enhances the security of exchanges by ensuring that sensitive data remains within the application ecosystem.

The main features of a messaging service include:
• Direct and group messages for targeted or collaborative conversations.
• Real-time notifications to quickly inform users of new messages.
• File and document sharing to facilitate content exchange.
• Conversation history to easily find past exchanges.
• User status (online, offline, busy) for better availability management.
• Message encryption to ensure communication confidentiality.

Do you have any idea what technologies you want to use?

Native mobile applications: These applications are developed specifically for a mobile operating system (Android, iOS). They use the device's native features for optimal performance. Examples: Instagram, WhatsApp.

Hybrid mobile applications: Developed once but running on both Android and iOS, they are often built with web technologies such as HTML, CSS, and JavaScript, then encapsulated in a native container. Examples: Uber, Instagram (initially).

Cross-platform applications: Using frameworks such as Flutter or React Native, these allow a single code base to be created for multiple platforms. Examples: Airbnb, Facebook.

Web Applications Statistics: These are simple applications where the content does not change often. Users access fixed pages that do not require much interaction. Examples: presentation web pages, blogs.

Dynamic Web Applications: These applications change their content based on user interactions. They are often connected to a database to display dynamic information. Examples: management platforms (ERP, CRM), social networks.

Progressive Web Apps (PWA): These applications behave like websites but can also work offline and can be installed on devices like mobile applications. Examples: Twitter Lite, Starbucks PWA.

Do you already have the UX/UI for your project?

UX (User Experience) and UI (User Interface) are essential elements because they represent the entire screen-by-screen design of the project.

We do this using Figma, a collaborative tool that allows you to see progress in real time and provide us with feedback very easily.

What are the "advanced features" of your project?

Do you have a document listing the features?

Are you familiar with the concept of MVP?

Do you have any competitors? Who are they?
