Version 2.2 FUEL • New: choose your fuel — pump petrol, E10, E15, ethanol-free, race or motocross — and the jetting is corrected with its stoichiometric ratio and density. CARBURETTOR ICING • New: an icing warning from the temperature and humidity. On enduro bikes (EXC, XC-W and MXC) it also warns at higher temperatures. TRACK MODE AND TRACK DAY • Your jetting full screen, large and high contrast, to read it in full sun with your helmet on. • A 12-hour track day: the main jet on the lock screen, in the Dynamic Island and on the Apple Watch. • The app follows the phone's dark mode. WIDGETS AND APPLE WATCH • Home and lock screen widgets and an Apple Watch app with complications. ALERTS • If the weather changes enough to change the main jet, it tells you. ICLOUD AND SHARING • The logbook and settings sync through iCloud between your devices. • Share your jetting with your mechanic as a link, a file or a QR code. AND ALSO • Location now works on iPads without GPS and indoors. • Report a problem from Results and from Help. • The distance to the station no longer shows as "0.0 km", and "More apps" looks better. IN PREVIOUS VERSIONS • 2.1: a fuel and oil mix calculator, and a new icon. • 2.0: a ride logbook, the weather station inside Conditions, a new launch screen, rewritten help and seven new model and year combinations.

New in this version: a mix calculator, and a new icon. • Mix calculator. It tells you how much oil to add to the petrol you are about to mix, and also the other way round: how much petrol the oil left in the bottle will take, or what ratio you actually ended up with. Litres, millilitres, US and imperial gallons and ounces, with petrol and oil in different units if that suits you. One button takes the resulting ratio to the Engine screen. It sits right below the oil ratio, which is where you need it. • New icon. The bike cut out in white on orange, like the rest of the family. The old one was a photograph, and at icon size you could not make anything out. • The ratio row is now called "Oil to petrol". The percentage is oil against petrol, not against the finished mix, and the row title is the place to answer that question. • The calculator has its own help screen, all of it translated into the app's seven languages. And what arrived in version 2.0, in case you missed it: • Logbook. Save any calculation and write down afterwards what you actually fitted and how it ran. Rate the low, mid and high circuits separately, note the place, and export everything as CSV or share a copy to move it to another phone. • The GPS tab is gone. Asking the nearest weather station for temperature, pressure and humidity now happens inside Conditions, which is where those values are used. No more going back and forth. • Seven new model/year combinations: 125 XC-W, 150 XC-W, 250 XC-W and 300 XC-W for 2017, the 125 XC for 2021 and 2022, and the 65 SX for 2009. • The weather station request no longer blocks the interface, and station names are no longer truncated. • Fixed: on the Results screen the Help, + and ... buttons sat on top of the first boxes. The layout now works itself out from the safe area, so it keeps working on any screen. • New launch screen with the app logo. The old one was a screenshot of the app with made-up figures, and it no longer looked like the current interface. • All the help texts rewritten screen by screen: they still described a GPS tab that no longer exists. • Fixed: the "more apps" screen showed titles without icons.
