Three plans of maintenance available depending on the needs of your application:

  • Soft

Maintenance plan is suggested to you based on the code quality, code age and the amount of work required. The assessment is done for free.



We assess all possible risks that can appear while submitting your application to Apple Store and include the right features to ensure your app does not face any major problems


Android applications are more agile in their use of the hardware potential. Android gives more variations and possibilities in the development of features on phone device control


Apple Watch, Fitbit, Samsung watch - the full variety of devices and softwares have their peculiarities in data transmission and processing. We focus on each such peculiarity to form the unified use cases

How do we ensure the delivery?

  • Detailed acceptance criteria and well structured specifications allow us to build the architecture of the scalable solution. Regular code reviews, cross code reviews are provided by the workflow. No Junior Developers work on the commercial projects. Autotests are introduced for quicker error identification, which saves time

    The quality is provided at several levels:

    1. before the code is written
    2. during code development
    3. while code testing
  • Taking the preliminary set of features we prioritize them based on the Kano method to identify core features for project success.

    Such features are developed first making the product potentially releasable once the core is done. This helps to ensure that even the most optimistic delivery dates can be met.

  • The estimated budget is provided with a range, giving min, max and average expected budget. As we move forward we are tracking the project progress against the project estimation.

    You get weekly updates if the project is going per min, max or average scenario. If at any point the risk of going beyond the budget becomes possible, we reiterate the features of the application to make sure we stay within it.

    According to statistics in 70% of the cases we are within the middle budget scenario.

  • Successful project comes out of the perfect combination of Budget, Deadlines and Quality. And we know how to take care of all three.

Native apps are developed for their particular platform, taking full advantage of the software and the operating systems' features. These apps can directly access the device's hardware such as the GPS, camera, microphone, etc. so their performance is faster, which ultimately results in better user experience.

We follow scrum methodology in the development of the projects. Scrum means that the development happens in iterations, where each iteration has a duration of 2 weeks and includes: specifications writing, wireframing, design, coding, testing. This means that in 2 weeks you will already be able to see the first bit of your app during a demo call and sent for installation to your device.
