Custom Mobile App Development Services

If you have only a conceptual outline of your future digital product, we can help you shape your idea into a business concept and create the terms of reference needed to start the development stage.

It depends on several factors: the goal of the app, its domain, geography, target audience profile, etc. According to Statista, Android had close to 70% share worldwide, while iOS accounted for around 25% in Jan 2022. Both operating systems are true leaders and have good prospects and growth potential.

Therefore, it is wise to have applications on both platforms by opting for cross-platform or hybrid engineering.

The right choice between these types of applications depends on the characteristics of your application, the habits and requirements of its target audience, and the limitations of your budget and dev team.

The native model involves creating an application for one platform using the native language of a particular operating system. This method is good for cases where there are no tight limits on timing and your team size, but there are high performance standards that must be met.

Cross-platform engineering is suitable for applications that are targeted toward audiences on multiple platforms. This option is suitable for low-cost applications that are built using frameworks.

The hybrid model is cost-effective and similar to the native one in many ways, but uses built-in browsers to work. Such applications are relatively inexpensive and fast to develop, but their UX is often inferior to native ones.

Similar to the cost, bespoke software development duration depends on the number of steps required and their complexity.

If the client does not have a detailed software requirement specification (SRS), we can provide an indicative estimate of what is required and then help work out the remaining details.

There is no fixed price for our custom mobile application development services. The cost depends on the amount of work and the time involved. For “turnkey” engineering, the cost depends on the following factors:

• whether the requirements are fully formed or need to be prepared with our help; 
• whether the design is ready or needs to be developed by us; 
• the platforms that need to be supported; 
• backend app development requirements; 
• interfaces (how well-designed, tested, and documented they are); 
• code design (including documentation); 
• testing and other project documentation. 

In the "team as a service" contract, the cost depends on the time spent on the creation of your app.

First, we sign an NDA (non-disclosure agreement) and clarify the details of the project. Then we draft a business proposal. Once the agreement is signed, our custom mobile app developers get to work and you can watch your idea come to life!

We transfer full or partial rights to your application. We discuss this at the outset. We may only grant usage rights for certain parts of the application (e.g. a library), while Promwad reserves ownership rights. Our customers place information on the rights and trademarks in the Terms and Conditions.

The documentation on our clients’ projects can be divided into the following groups:
1. Requirements + architecture.
2. Technical description of features.
3. Comments in our code.
4. User documentation.


We do the architecture documentation together with our client. As for the technical documentation, its scope is determined separately, depending on the application complexity and the need for tech support by a third-party team. Timing and cost increase accordingly.
