What's New in Contraptor

1.0.7

October 21, 2026

- Over 800 Challenges to solve in Community, with more added every day by players. - A whole new sky while your machine runs: layers of clouds drift past, rushing by when a piece really falls, and anything that flies high enough fades into space with stars. - Falling pieces heat up: first a faint smoke, then a glowing leading edge, until the piece burns white-hot inside a long fiery tail, with a rushing roar to match. - When a piece falls far out of your scene, the ground comes into view: blazing pieces leave craters and explosions that echo off distant mountains, the camera follows each impact, and a bird flies by when it's all over. - Watching a Solution from Community now shows all of the same effects. - Shared videos run a little longer, so friends see more of the action. - The machine's clatter fades away as the camera follows a piece far from it. - Fixed: machine sounds now play through AirPlay along with everything else. - The "Run again at 1X" box dims the screen less, and Cancel now just closes it without stopping your run. - When a new version of Contraptor is out, the reminder at the top now shows each time you open the app until you update. - Fixed: a new piece added while zoomed in on a Work Area could land out of view; it now drops into the part of the Work Area you can see. - Fixed: moving a rod end where a Space Motor rod meets a Space Pinned rod no longer turns the one-arrow motor into a two-arrow one. - The Community banner now also shows how many challenges are posted in all, and how many you haven't solved yet. - Fixed: the first star rating you gave a Community challenge could stay missing from its card in the feed for several minutes, even after refreshing. - Fixed: the Terms screen on first launch could freeze for a moment on older iPhones, especially when tapping the age box. - New: a Find My Work Area button (just above Find My Stuff) jumps the camera to the area you're allowed to build in, and while you're Watching a piece, a Find My Watched Item button brings it back to the middle of the screen. - iPhone: the new-version banner no longer covers the buttons at the top of the screen. - Fixed: a Welded rod end moved onto a shape could fail to hold it once the machine ran, even though the shape lit up yellow as you dropped it there. - Fixed: when you Watch a fast-moving piece, especially at 8x speed, the camera now keeps up with it instead of falling behind. - Fixed: posting or saving could freeze the app for up to half a minute while it made the picture for the card. - A selected rod end with a motor is easier to grab and drag again. - Community opens faster the first time: challenges appear as soon as they arrive, and likes, ratings and badges fill in a moment later. - Smoother start: the launch screen now stays up while the app gets ready, then fades into a fully loaded Home and Terms screen instead of stuttering. - Fixed: older machines that are a touch over the bonded weight limit play again, and Lighten to Fit now always brings a too-heavy set under the limit. - Your Activity bell now checks for news in the background, so new follows, likes and solves are waiting when you open the app. - Leaderboard: Plays and Likes now show real numbers, and the up/down arrows show how each builder moved since about a day ago. - Fixed: the view count on Community challenges now counts everyone who plays them; before, only the author's own plays were counted. - Fixed: opening the bell now always checks for new activity, so it no longer shows an old, partial list until you pull to refresh. - Home screen machines run smoother: very heavy ones no longer cause a stutter, and long ones speed up so you get to see them finish. - iPhone Home screen tidied up: the version label no longer hides under the top buttons, and the purple background now fills the whole screen. - Fixed: the Home screen machines now really pause while Settings or another screen covers them, saving battery.
