The 5 most popular questions

App dev projects are Notorious for exceeding their budgets and failing the deadlines. There is even a rule of “Pi”: multiplay your project’s budget and timeline by 3.14 to get an accurate estimate.
#1 reason: Clients are in a hurry to get an estimate, and most developers are in a hurry to oblige. They quickly quote the prices and timelines without completely understanding the project.

No wonder, on average, only 34% of projects remain within their estimates. Our percentage is 92%.

It is that high because we invest time and effort into knowing your project. To get an accurate quote:

To help our employees spend more time on important tasks and less time on reporting, we built Time Tracker. Time Tracker is automatically synchronized with JIRA so it makes the time tracking process simple and clean.


J2P provides a simple solution for providing synchronization between JIRA and Pivotal Tracker. As a result, all the user stories that you put in the Pivotal Tracker system will be automatically organized in JIRA as separate tickets with the corresponding fixed versions.


Planifica is a tool that simplifies resource management in teams and improves resource allocation. The administrator can set the team's individual work hours, local public holidays or time off. You can always check who's overbooked and who's on vacation.

What drives us

"For more than 10 years of being in the industry, I have seen plenty of business people invest a lot into the development of web-based or mobile apps, only to end up with half-baked products and no budget for marketing. In other words, it's the worst possible scenario for any startup, which is not how we see the future of our clients.

That's why we leverage every piece of our technical and management expertise to approach the development process in a way that our clients can have everything necessary for an early market launch. That is a modern product with just enough features to delight its users and the marketing budget to help it grow. The only way we grow is together!"
