Read full descriptionHide full description
This simple simulator shows how space and time behave at relativistic velocities. It was developed as a pedagogical tool as part of a master's dissertation at the Federal University of Espírito Santo. Thus, it does not take into account the acceleration effects of the spacecraft. It was developed in a partnership between Prof Thiéberson Gomes (UFES), Prof Flávio Gimenes (UFES) and student Luiz Henrique Gobbi, with computational support Rodrigo Marques.

Verdict
The clearest difference is update cadence: Copernicus Touchbook at every 2 weeks against Relativistic Space's every 75 months. Copernicus Touchbook also leads on iOS requirement (9.0 vs 13.0). Relativistic Space's advantage is device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.
