Space Flight Simulator Lite is a free realistic 3D space travel simulator and planetarium for Android. This app offers a journey through the Solar System, with all the major planets and moons, including realistic keplerian orbits. Users can also explore several extrasolar systems, such as Alpha Centauri, Barnard's Star, Sirius, and Epsilon Eridani. The app features a realistic calculation of fuel requirements using Tsiolkovsky Rocket equation, and a timeslider to accelerate/decelerate time. The app also offers a new free flight mode, where users can take control of their spaceship with a limited amount of fuel and experience the effect of gravity on their trajectories.

In the full version, users can enjoy improved graphics for planets, moons, and stars, as well as many more extrasolar systems. They can also experience realistic orbits from any planet to any other planet and moon, interstellar travel, and the relativistic effects of time dilation, length contraction, and relativistic doppler shift during interstellar flights. If users encounter any issues with the app due to insufficient heap memory, they can try to change the heap size configuration of their device with applications like SystemControlFree. Please note that the developer welcomes any complaints or suggestions through email.
