A mobile app for Counter-Strike: Global Offensive players with check-ins, combining rankings with geolocation.

Client: RANKmapp

Category: Mobile App

Date: January 2018 (beta)

RANKmapp’s name is telling: this mobile app combines rankings with maps. Its target audience are Counter-Strike: Global Offensive players, enthusiastic and highly competitive. Using the mobile app, the user can learn how good their geographical neighbors are at CS:GO, where they are located, and also how big is the circular area where the user is #1.



Global Rank Softwareentwicklung UG chose Bamboo Agile to deliver a mobile rankings app that required integration with multiple external API’s, including Steam, Google Places, and OpenStreetMap, and also real-time user tracking plus location search and storage over the entire OSM database.


Developing a special algorithm allowing to store the geodata and calculate rankings at any given time. Implementing multiple optimizations and custom bypasses to the back-end part of the project (due to the algorithm being demanding to processing power).


A complex project featuring back-end and mobile parts, highly informative and entertaining for the audience.
