Track mode, your fuel, widgets, Apple Watch, alerts and iCloud. - Fuel: pick 98 E5, E10, E15, ethanol-free, leaded or oxygenated race fuel, or your own values, and the jetting is corrected for it. The Engine tab tells you what it does to the main jet. - Carburettor icing warning, from the temperature and humidity. - Track mode: the jetting full screen, huge and in high contrast, always on and at full brightness. Start a track day from there and show your mechanic a QR code. - Widgets, Lock Screen, Live Activity and Apple Watch, with complications. - Alerts when the weather changes enough to change the main jet. - Share the jetting with your mechanic by link, QR code or file. - Logbook and settings sync through iCloud, and the logbook now records the fuel. - Dark mode, a redesigned More Apps screen, and location that works on iPads without GPS. - Fixes: the region no longer changes when you change the phone's language, changing bike no longer resets your oil mix, and the nearest part is now chosen correctly at the ends of each list.
