Inside Us is an endless running game that can run offline, which means you can play anytime, anywhere! The city was attacked by a very rare virus and no cure for this disease has yet been invented. And only one unique character was able to come up with a temporary solution to save humanity - to kill the virus from the inside. And for this, they made a tool with which you can shrink to a microscopic size, to be the same size as bacteria. And now this character saves people's lives by studying the human body, fighting the bacteria inside of us. Run in the human body, dodge obstacles, and fight bacteria to rid the human of diseases. CHARACTER CONTROL IN THE GAME: To hit the bacterium, you must click on the screen when the character is next to the enemy. Lightning trigger game for moving and jumping hero. To move around the human body, use swipes left and right. To jump, swipe up from the bottom. If you liked the game, then let us know about it, leave a review so that even more people know about us.

Read full description

Zoom from a planet's surface out to distant galaxies, then reshape the whole system with your own hands. Solar System Sim is a real-time gravity sandbox built on Newton's laws and real astronomical data. Every body you add, move or destroy recalculates the orbits of everything else, live. • Smash worlds together: impact craters carve into the surface, firestorms sweep the globe, and glowing debris rains back down. • Build your own universe: add planets, moons, asteroids and comets with their own size, mass and looks, or customise the ones already there. • Land anywhere: drop to a first-person view on any planet's surface and experience its environment. • Sculpt rings: add particle rings and watch gravity shape them in real time. • Witness real eclipses: solar and lunar, with real-world astronomical precision. • Follow comets: watch them streak past and interact with the bodies they meet. • Leave the Solar System: travel to remarkable nearby stars and find them within the Milky Way. • Feel the scale: see the true vastness of space, from a pebble-sized moon to the nearest galaxies. Whether you're here to learn how gravity really works or just to break planets with it, explore at your own pace. Start your cosmic adventure with Solar System Sim.

Verdict

The call

The clearest difference is in-app purchases: Inside Us at none against Solar System Sim's 5. Inside Us also leads on ads (none vs shown) and iOS requirement (11.0 vs 15.0). Solar System Sim's advantage is update cadence (every 5 days vs every 2 months). On price and device support there is nothing between them.
