Lab: a new Pressure view, now live in all four scenes, with numeric readouts. Lab › Track Wing: corrected the angle-of-attack sign — the wing now produces downforce the way it sits on the car, with the Ca reading, pressure colors, and flow arrows matching the M1–M4 markers. Lab scenes now run noticeably faster. Lab HUD: added live Fz/Fx readouts.

FlatSixDynamics now includes every feature for everyone, free. FlatSixDynamics 2.0.2 removes the in-app purchase; every feature is now available to all users for free, and the previously offered 'Full Access' purchase is not shown anywhere in this build. The IAP record remains registered in App Store Connect only to preserve restore/entitlement history for existing purchasers.

minor bugs fixed

FlatSixDynamics is now free to try: live airflow on the reference car, no account, no subscription. Unlock the full speed range, pressure & lab views, every setup, and your own car from a photo with a single one-time purchase (Full Access). No subscription. Bought the app before version 2.0? You keep everything — nothing to do. If anything looks locked, use Restore Purchases in Settings.

New reference car: fixed rear wing. Select it alongside the active spoiler and compare how each rear end shapes the flow. Marked Beta while on-device testing completes. Small fixes and refinements throughout.

minor bugs fixed

Feel the airflow more clearly. This update brings smoother real-time visualization, improved photo calibration, and refined pressure displays.

NEW: Photo Import - bring your own sportscar into FlatSixDynamics. Snap a photo of your car and see We've also sharpened accuracy and visual fidelity across the board.

Fixed several minor issues and improved the overall experience.

Version 1.6 brings a calmer, more cinematic view of the airflow. • Presentation Mode — a new one-tap toggle that clears away the technical overlay, leaving just the car, the flow, and the speed front and center. Perfect for screenshots, or simply watching. • A richer, higher-contrast backdrop makes pressure and speed colors read more vividly against the car. • Refined controls — every button and toggle now shares the same clean, glass-pill look across the car view and the labs. • Smoother airflow through fast speed changes, with more even coverage right to the edges of the view. Thank you for flying with us.

Meet the Setup Lab: drop the ride height through three stages — Serie, Sport, and Track — and watch the body settle live over the underbody flow. A setup-delta readout shows exactly what each stage changes, with no ranking or "best setup" claims — just honest numbers for you to read. A new help sheet walks through how the splitter lip and diffuser trade off against each other, and why the effect shifts with speed. The control panel is also more compact now, so the underbody view has more room to breathe.

Version 1.2 introduces live streamlines — and makes the whole app faster. • New — Streamlines: watch the airflow trace continuous lines over the car in real time, alongside the pressure and vector views. • Faster throughout: a leaner graphics path delivers a quicker launch and a smoother, more responsive live simulation on device. • A cleaner flow field: the wake behind the car and the underbody now read more continuously. Thank you for flying with us.

Version 1.1 opens up the Labs • Flow Labs for everyone — the three interactive flow studies are no longer hidden. Explore the cylinder wake, the airfoil, and the nozzle whenever you like. • Velocity-colored vectors — flow arrows now take their color from local speed, so acceleration and separation read at a glance. • Deeper explanations — an expanded introduction and in-app Deep Dives walk you through the physics behind each scene. • Pinch to zoom — move in close on the boundary layer, the shock, the wake. • Smoother and faster — a reworked render path keeps the simulation fluid on a wider range of devices. • Refined app icon and a handful of stability fixes, including a faster, more reliable launch.
