Notes
Release notes and short writing from the development of FlatSixDynamics. We post when there is something worth posting.
Version 2.0.2
October 2026
Version 2.0.2 removes the in-app purchase. Everything is free, for everyone.
- Everything included: the full speed range, every view, every setup, and your own car from a photo — no purchase required.
- Already bought Full Access? Thank you for the early support — nothing changes for you.
Thank you for flying with us.
Version 2.0
September 2026
Version 2.0 makes FlatSixDynamics free to try.
- Free to try: live airflow on the reference car, no account, no subscription, no time limit.
- Full Access: a single one-time purchase unlocks the full speed range, the pressure and Lab views, every setup, and your own car from a photo. No subscription.
- Bought the app before 2.0? You keep everything — nothing to do. If anything looks locked, use Restore Purchases in Settings.
Thank you for flying with us.
Version 1.9.2
September 2026
Version 1.9.2 introduces the Fixed Rear Wing — a second answer to the same question the spoiler asks.
- New — Fixed Rear Wing (Beta): choose a fixed wing in place of the active spoiler and watch the wake close differently behind it — the same live air, holding a different shape.
- Refinements throughout, with the usual quiet fixes.
Thank you for flying with us.
Version 1.8
August 2026
Version 1.8 introduces Photo Import — bring your own car into the airflow.
- New — Photo Import: point your iPhone at any fast car and bring it into FlatSixDynamics; a quick on-screen alignment locks it into the stream, and the live airflow moves around the exact shape you photographed.
- Sharper accuracy and visual fidelity across the board.
Thank you for flying with us.
Version 1.6
July 2026
Version 1.6 introduces the Track Wing Lab — and gives every flow study a path to follow.
- New — Track Wing Lab: push a wing's angle past its working range and watch the flow start to buffet, live — not a number on a chart, the thing itself.
- Tracer pathlines, everywhere: the Cylinder, Airfoil, and Track Wing studies now trace continuous paths through the air, alongside the existing color field.
- A plain-language read on the narrowing-channel case: a short line under the slider explains what's happening as you push the flow harder — no jargon required.
- A tighter Lab layout: panels, toggles, and readouts refreshed for clarity across every scene.
- Smoother throughout, with refined visuals and a handful of stability fixes.
Thank you for flying with us.
Version 1.4
July 2026
Version 1.4 introduces the Setup Lab — ride height, live, and no ranking attached.
- New — Setup Lab: step through three ride-height stages, Serie, Sport, and Track, and watch the body settle visibly lower over the underbody flow.
- Setup delta, honestly: a readout shows exactly what each stage changes — plain numbers, no ranking, no claim of a “best” setup.
- New help sheet: a walkthrough of how the splitter lip and the diffuser trade off against each other, and how that balance shifts with speed.
- A leaner control panel: more compact throughout, so the underbody view has more room to breathe.
Thank you for flying with us.
Version 1.2
June 21, 2026
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
June 2026
Version 1.1 opens up the Labs.
- Flow Labs for everyone: the three interactive flow studies are no longer hidden — the cylinder wake, the airfoil, and the nozzle, whenever you like.
- Velocity-colored vectors: flow arrows 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, with a faster, more reliable launch.
