Highly recommended! We took a long time to review a long list of candidates from 3 continents and we ended up choosing Onix for building our non-trivial iOS app. The job required in-depth knowledge of obj-c, Cocoa and iOS platform, animation techniques and usage of plethora of external libraries, APIs and tools. Onix devs were verbose, communicative and supportive during the whole process. We've received exactly what we were looking for, even though requirements were evolving. We wouldn't think twice about choosing Onix again and couldn't be happier that we now have an outsourcing partner for all our future iOS needs!

Onix-Systems has done a wonderful job building the Jumper iOS application, I have worked with many experienced developers in the US as well as many different countries around the world and the Onix team has produced the best code base. Their protect management is on high level and focused on getting the job done on time. I am amazed how much they care about producing great applications and not just trying to earn a buck or two. Great guys to form long lasting relationships, highly recommended!

Onix-Systems has accelerated our Android development and time to market, matching our own culture with a start-up mentality and speed. Working with an external team can be difficult but Onix has been responsive and proactive in problem solving. They’ve often gone the extra mile to meet our deadlines. Our work is technically challenging and they have the relevant skills to tackle the project. We’re happy to recommend them.

As a self-funded start-up company, we aimed to create a web product that could provide a solution to all types of customers, including enterprises, and meet quality test protocols. Onix has proved to be the best partner a start-up company can ask for. They have great developers, the quality of product they supply is high, and the price is more than reasonable. But the best thing about them, is that they actually care about the product and our success, they helped us out with new ideas, with UX/UI suggestions, so now, before making any big decision, we consult our project manager at Onix.
