Yes, we can help you with both iOS and Android platforms. Our team has the expertise and experience to develop high-quality and engaging mobile apps for both platforms.

The timeline for developing a mobile app depends on the complexity of the project and the number of features involved. Our team will work with you to determine a timeline that meets your specific needs and goals.

We use the Agile method , more specifically the Scrum , originally invented for IT development companies . Often opposed to the Waterfall method which consists in following a set of specifications defined at the beginning of the project, without interaction with the customer until the delivery of the product, the Agile approach , it advocates collaboration with customers and frequent deliveries. of the product throughout the project, which makes it possible to adapt to changes.

Each project is divided into several phases: at the beginning of each, you list, with the help of our Product Owner (the person in charge of explaining your wishes to the development team) all the functionalities to be developed during this stage and at the end of it, we deliver a version of your mobile application (which will be more and more developed) in order to test it and request changes if necessary for the next phase. We repeat this cycle until your product is fully developed. After each step, we take the time to analyze our work in order to list the positive points to be reinforced and the negative points to be improved.

The goal of this method is to offer you the best possible solution to meet your needs.

Generally, if we count the back office and the mobile application (both Android and IOS) with a few screens and a quality design, your application will cost a minimum of €20,000 excluding VAT .

This does not mean that it is not possible to make a cheaper application because our mobile application development agency does , but you should know that a standard application present in the App Store / Google Play costs between 20,000 and 40,000€ excluding VAT to be developed. The price may increase depending on the features, the number of screens (normally, an application is relatively simple and requires few screens but the price increases if it takes a lot), if it is necessary to do A/B testing, continuous adjustments…

It is possible to make an application at a lower budget, but keep in mind that it will be a simpler application. You can also opt for the web format if we find that the mobile (iOS/Android) is not suitable for your budget . We then develop a responsive web interface (adapted to mobile). In this case, call on our web agency expertise instead , your budget will then be lower.

There are several types of applications: native, hybrid and web. They each have their specificities.

are Native apps apps that you download and install on your smartphone. They are developed for a specific operating system, Android or IOS. They require different developments and languages ​​for each system: Java and Kotlin for Android and Objective-C and Swift for IOS. This distinct development makes it possible to obtain a robust and powerful mobile application.

are Web apps roughly the mobile version of a website . These applications do not download or install on your smartphone, you access them from a browser. The disadvantage of this type of mobile application is that it requires a connection to work. But, the main advantage is that it is compatible with Android and IOS with a single code, it saves time and money.

are Hybrid apps a mix of native and web apps. They only require a single code to be compatible with IOS and Android like web applications, but they are downloaded and installed on your smartphone like native applications. Hybrid apps were, at first, less efficient than native apps but today there are technologies like Flutter and React Native that can compete.


A first difference lies in their audience: the IOS audience is more likely to buy a mobile app or spend money on an app than the Android audience. This is an element to take into account especially if you plan to charge for your application.

If you choose a native application, you will have to develop the application twice: once for IOS and once for Android. If you opt for a hybrid application (application that requires only one code for both operating systems), you will still have a small additional cost of wanting to be present on both operating systems.

Some customers will choose to launch first on IOS or Android and sometimes on both at the same time, but it all depends on their budget and their desires. Our mobile application development agency can help you determine which solution to choose. If you have an application project, contact us , we will talk about it together.

Yes, it is not free. To be published on the App Store and Google Play, you must count a hundred euros per year per store. To do this, you must create a developer account that will allow you to manage the publication of your mobile application but also the comments left and the payments made by users, which is very interesting.

If you ever do not want to opt for this solution, our mobile application development agency offers you to publish your application on our developer account and in this case, it’s free. But, your application will be on the 01COMMUNICATION account, you will not have as many possibilities as on your own account.


It’s difficult to give a precise answer because each mobile application is unique and requires a different development time. Generally, in our mobile application agency, we count from 3 to 6 months between the beginning and the end of the project . Of course, it all depends on the complexity of your application and the number of screens.

Keep in mind that well-known applications like Facebook or Instagram require endless development because there are constantly modifications to be made to the applications. In this case, there is a version 1 which is continuously improved. The project then lasts much longer. This kind of continuous development is a smart move if you find your concept working.

To get a precise idea of ​​the development time of your application, we advise you to contact us . We will discuss your project together.


In general, updates can take time especially at Apple, as can the first publication of a mobile application in the App Store. Apple is very strict with the applications present in its App Store and each publication must be validated by a human (no automated process) which takes some time given the number of mobile applications in the App Store.

You have to be very careful when updating an application because when there is a bug on the mobile, you obviously have to make an update to correct this bug, but it is not guaranteed that all users will switch to the latest version of the app. So you have to be very careful to avoid bugs. This is less the case in web development .

Updates require rigorous testing, which our mobile app development company does with great care, of course.


First, we ask you if you already have a graphic charter and a logo because these are elements that strongly influence the design.

Next, we ask you to list mobile applications that you use regularly and whose design you like . Here, we are not talking about the interface part, usability of these applications but about their design. This list will help us know where you want to go.

Finally, our designer , on the basis of this data and the wireframes (models of the application which are used to structure the screens of the application: cf. point 6 of our article) that we will have produced beforehand, will submit a design proposal to you. . This first version of a part of the application is used to know what you like or not. You can give us some feedback so that we can adapt your design. The goal of our mobile application agency is to produce the design you like.

In general, our mobile application development agency transfers the exploitation rights of our creations to our customers. For more information, please see our terms and conditions of sale .

Our customers can do whatever they want from the mobile application we have developed . On the other hand, there is a distinction to be made: some parts of the application are based on technologies, libraries like Django , React JS or Flutter and their intellectual property belongs to these technologies and these libraries.

The same is true for the 01COMMUNICATION libraries that we make available to our customers and whose intellectual property we retain. However, you retain the right to use these libraries and technologies.

But, all the code developed specifically for our customers belongs to them. The source code can be delivered at the end of the project if the client requests it.


You should know that there is a difference between maintenance and the continuous improvement of your project. Traditional maintenance concerns updating and fixing bugs on your mobile application and continuous improvement, meanwhile, is the addition of new features, adaptations to your application , it is its evolution that does not therefore not part of maintenance.

Maintenance varies whether you choose to host with us or not. Indeed, our mobile application company offers a hosting contract with maintenance. In this case, we take care of it.

If you do not host your mobile application with us and you have small requests, we will take care of them. But, if your requests involve a considerable number of working days, then generally, we will divide your requests into sprints (= work phase: we divide our work into several phases as recommended by the Agile project management method) in order to plan your budget more easily.
