Train Tracker vs GravyLensing

Train Tracker is a simple but addictive inclusive game for all ages with a great plus – switch access options for single and two switch users. Choose your train and then build a track from a choice of straights, curves and cross-over tiles. Select ‘play’ and your engine and coaches, full of passengers, will steam around your track with great sound effects. Select ‘stop’ to alter or extend your layout. Select the ‘snapshot’ button to add a picture of the current layout to your gallery – enabling you to keep a record of your favourite tracks. Compare them with friends to see who can build the best and biggest layout! The easy to use interface and “snap in place” feature makes Train Tracker an accessible game which will help develop perceptual and planning skills. Switch access options with simplified scanning can be used at a ‘cause and effect’ level as well as allowing the user to build more complex systems. Key features: • Simple, engaging and addictive for all users, not just train fans! • Switch access for single and two switch users. • Snapshot feature to take a picture of your favourite tracks. • Can help to develop thinking, problem solving and perceptual skills. • Compatible with all currently available switch interfaces (See our App Support page for more information). • Runs in landscape mode only.

GravyLensing brings gravitational lensing, the cosmic phenomenon where space-time bends around massive objects, into your hands. ESA's Euclid mission is mapping this effect across billions of galaxies to reveal the dark universe. Now you can explore that same physics yourself. Point your camera anywhere and watch space-time bend like light passing through a galaxy cluster. Built on the same Singular Isothermal Ellipsoid (SIE) models astronomers use, every lens is a real galaxy cluster observed by Hubble, JWST, and Euclid, faithfully recreated on your device. Features • Apply scientifically accurate gravitational lensing to your live camera feed, photos, or videos • Browse a gallery of real galaxy clusters, each with their own unique lensing signature • Touch and drag to position the lens exactly where you want it • Adjust distance to sweep from subtle warping to extreme Einstein rings • Record warped video or capture still images and save them to your photo library Inspired by ESA's Euclid mission to map the dark universe, GravyLensing puts the physics of warped spacetime in your pocket. No ads. No data collection. Just physics.
