In this simulation, you are asked to calculate some measurements of celestial bodies, such as area, perimeter, and volume. To do so, a holographic projector is available for the observation and measurement of the necessary distances. The correct calculation of these properties will help the astronauts learn more about the new planetary system.

Verdict
The clearest difference is in-app purchases: CloudLabs Planetary system at none against GridMath's 3. CloudLabs Planetary system also leads on iOS requirement (11.0 vs 13.0). GridMath's advantage is update cadence (daily vs every 8 months). On price, ads and device support there is nothing between them.
