Planet Gravity isn't just about gravity anymore. Select a planet to get a scrolling fact about that planet on the display. This app is a twist on the Newtonβs cradle balance balls. The pendulum balls collide just like the real set and you can select other planets to use that planetβs gravity. How does the pendulum swing with different gravity? Even the Sun has gravity - see what it does to the motion of the pendulums (well they'd probably melt but you get the idea.....)

Verdict
The clearest difference is price: Planet Gravity at Free against Simple Classic Maze's $4.99. Simple Classic Maze's advantage is update cadence (weekly vs every 14 months) and iOS requirement (13.0 vs 17.6). On ads, in-app purchases and device support there is nothing between them.
