    AR Mobile Game with Precise Geo-positioning & Advanced Gameplay

    Blacksnowgames, Inc. was created with an idea of launching an innovative AR game enabling full player immersion effect

    • on a regular smartphone
    • with no extra hardware
    • and no time-consuming pre-calibration procedures

    The game

    Sigma Software team delivered is built on top of a custom AR engine and:
    1. Employs almost every sensor a modern smartphone has (cameras for better gameplay impression, compass and GPS for positioning, gyroscope and accelerator for haptic control).
    2. Stretches the playing area for 2 kilometers in every direction from the player’s location achieving accurate player geo-positioning through the integration with a cartographic service.
    3. Combines graphic alignment with surround sound and haptic feedback to safeguard player’s full immersion.
    4. Executes calibrations in a hidden from the user mode to eliminate time-consuming pre-calibration and make AR gameplay immediately accessible. 


    However sophisticated, the game would not hit the market unless it has visual appeal and a thrilling plot. Thus, we spiced the product with the following:

    • Real-time multiplayer capabilities
    • Combination of several game mechanics - cards collection game, geo game, and AR game 
    • Cinematic gameplay
    • Fascinating game art - 3D visuals and special effects

    The game went Live on the App Store in June 2019 and is now available in 18 countries, while the team continues expanding the game.

    Budgeting IT Systems Modernization, Support and Maintenance Image

    Budgeting IT Systems Modernization, Support and Maintenance


    Faced with a strong competition within the industry, SAS adopted 4XNG strategy aimed at halving IT costs over the upcoming 5-year period.

    One of the steps in 4XNG strategy included replacement of the Airport Charges legacy system with something less costly to maintain. Sigma won the bidding process and was contracted to perform the development and

    implementation of the New Charges System.

    SAS was impressed with our ways of work and decided to outsource support and maintenance of the whole Budgeting Ecosystem (10 different systems including Charges Management) with us.


    So, we took over support and maintenance and continued systems optimization:

    Implemented New Charges system that provides daily direct cost calculations for each route based on the info from the SAS flight planning system

    Extended the system with 3 additional modules that replaced several other legacy systems:

    • Activity Based Calculation that performs budget and actual direct & indirect costs calculation for every single flight
    • Fuel Management module responsible for handling actual consumption and costs for jet fuel
    • Invoicing module performing automated invoice control and verification

    Optimized support & maintenance processes to reduce maintenance costs for 5 additional systems we work with


    Those improvements enabled SAS halve their IT costs within only 3 years (2 years faster than initially planned).

    Moreover, the optimizations we introduced brought more efficiency and speed to the whole business process. For example, fuel budget calculation now takes only 25 minutes which is an amazing achievement if compared to 70 hours it took with the old systems.

    Centralized System to Recruit Patients & Manage Data for Clinical Studies

    AstraZeneca contracted Sigma Software to deliver a system that would streamline patients’ recruitment for clinical studies.

    The solution Sigma Software has delivered is integrated into AstraZeneca IT ecosystem and is used by clinics in Sweden, Denmark, Finland, and the Netherlands to determine COPD patients suitable and ready for participation in clinical



    Our biggest challenges through the project were:


    The system interface is designed to be as clear and simple as possible to make sure the personnel in clinics can fill in and manage all the data with just a few clicks.

    In order to achieve this, Sigma Software UX experts analyzed daily clinic processes and systems, created prototypes, and tested those with clinic personnel onsite.

    This enabled us to make sure both the interface and the flow are intuitive and clear to the end-users.


    The system is used to handle very sensitive information. Thus, security was a common thread going through the whole project specification.

    The solution we designed as a secure web application accessible with one-time password technology. Every clinic is considered as a separate data entry point and is securely isolated from other clinics data structure and data storage.


    The team successfully coped with the challenges, delivered the solution, and has transferred the system to support & maintenance.

    SaaS Product Dev for Ad Tech Firm

    "Although their native language isn’t English, they're far better than others in terms of understanding."

    Willing to refer: 
    The Project
    $1,000,000 - $9,999,999
    2013 - Ongoing
    Project summary: 

    Sigma Software developed and launched the functional version of a preconceived advertising platform. The assigned dev team now focuses primarily on bug fixes and feature customization.

    Founder & CEO, Zapp360
    The Review
    Feedback summary: 

    The launched ad platform began generating revenue within 6 months, which might not have been possible if it weren't for the proactive involvement of the assigned project team. Another key strength is their flexibility with rapidly evolving requirements.

    A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.


    Introduce your business and what you do there.

    Zapp360 is a software-as-a-service ad-based platform for local marketers. We sell and channel through local resellers looking to use digital tools in order to engage better with their audiences and drive traffic into stores, to events, or for the services they provide. I am the founder and CEO of the company.


    What challenge were you trying to address with Sigma Software?

    We needed tech developers. We had scoped out a rough idea of what we wanted to bring to market but had no technical skills to build the actual product.


    What was the scope of their involvement?

    Sigma Software took our platform from wireframe to reality, providing interface design and coding. We're constantly making new developments and maintaining the platform, so Sigma Software remains a key resource in our world. We also have internal product managers, but Sigma Software provides most of the coding.

    Sigma Software assigned 8–12 developers to our project. As we added new requirements and expanded the budget for executing on those requirements, the team size grew. Our resources include C++ and JavaScript developers, designers, QA specialists, and database managers. We have a one-to-one collaboration, with a key product manager on our side interfacing with Sigma Software's liaison. Their manager has been integral to our product's success. We do interface with Sigma Software's resources directly from time to time.

    How did you come to work with Sigma Software?

    I used to be engaged with a company that used Sigma Software's services. We also looked out to the market for partners with end-to-end capabilities for making our platform come to life. We looked in places like India, but also locally, in the US and UK. We also considered hiring in-house resources but came to the conclusion that Sigma Software would be the best choice for creating a market-ready platform in under 6 months.

    How much have you invested with Sigma Software?

    The cost of Sigma Software's work has been above one million dollars.

    What is the status of this engagement?

    We started working with Sigma Software in early 2013.


    Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

    The platform built by Sigma Software became live and revenue-generating within 6 months. There was a lot of feedback in that short period of time, with tweaks, upgrades, and changes to the development schedule. Sigma Software was accommodating and flexible in doing this.

    They worked with us in interpreting what we were trying to get done. Our main expertise was around the marketing for a software-as-a-service platform. This kind of interpretation can't happen in a vacuum, but rather through the organic collaboration between coders, designers, and technologists acting as business visionaries.

    How did Sigma Software perform from a project management standpoint?

    Working within two different time zones has given us time to think and develop requirements, with Sigma Software resuming work while we were sleeping.

    We used Skype for live chats, which occurred on a regular basis: daily during the early stages and weekly at the moment. We also used certain software for tech development and timeline tracking on Sigma Software's side, as well as phone and email.

    What did you find most impressive about Sigma Software?

    One of the reasons for outsourcing a particular component of a business is the gained efficiency, as well as access to the know-how and resources available in certain parts of the world. There are barriers in terms of time zones, cultures, and languages, but Sigma Software embraced our way of communicating. Although their native language isn’t English, they were far better than others in terms of understanding what we were trying to do, regurgitating it back to us, and executing it. I found this aspect to be unique, compared to other outsourcing shops.

    Are there any areas Sigma Software could improve?

    I can't think of anything off the top of my head. We consider Sigma Software to be a strategic partner and an integral part of what we're doing at this time. They've grown as a company since our first interactions, adding offices in the US and other locations.
