Hi!
I'd like to place your attention to a newly released smartphone app called Stairways. Stairways provides an easy-to-use sports ladder, a well-known concept within table tennis. The app is suitable for table tennis players at all levels, but also organizations who is interested in organizing ladders for its members or customers, such as sport clubs or sport arenas.
The app works for both iPhones and Androids, and can be downloaded from AppStore or Google Play. More info can be found on

Best regards.
