Better than I thought, but improvements are possible
Having said that, there are still somethings that could make this tool better (unless this is another case of user error… lol), though in the grand scheme, I stand by my initial verdict that this can be the most powerful tune tool for Forza (I can’t speak for other platforms).
Forza just released new vehicles with their last update (almost a week ago). Many of those vehicles are still not available for tuning. I’m sure the developers are working on this. I’m curious as to whether there’s a way to pull up a help menu. I’d also like to see some more alternative options for tuning and building. For example, (this is one of my favorite things about this app) the app gives helpful hints like “lower speed to 7.1 for best handling. Alternatively, you can lower handling to 6.1.” It would be awesome if, when choosing a performance part it would do the same. For example, it will recommend a wheel for best handling. If I don’t like those wheels and decide to choose a lighter wheel, it could suggest: “for best handling, choose recommended wheel. Alternatively, if you choose to stick with this wheel, increase rim size to 20” diameter (or similar)”.
I realize this is a pipe dream as I’m sure that would be a ridiculous amount of research, etc. it’s really more of a want than a need, though. Other than that, this app is EXCELLENT and I highly recommend it.

Thank you for the updated review, much appreciated! The app does recommend you wheels (on the Recommended tab in the Rims screen). I try to update the app on a weekly basis with new content but sometimes the review takes longer or life gets in the way.
Potential, but ultimately falls short
Response from developer
You can absolutely tune a car to a different performance class but the app doesn’t know PI costs of each and every upgrade part so you have to manually update the PI and other stats like power & weight after you have installed the upgrades in-game in the Stats card. To tune a car to a different performance class than the car’s stock performance class select the required performance class in the Start screen then advance to the Build screen, install upgrades and update upgrades and resulting stats in the Upgrades card and Stats card.
Does not give correct results
Waste of money and deleted

Thank you! As for track tunes: I use the app myself for seasonal events and have usually no problems completing the events. Please make sure you enter all installed upgrades exactly in the app, especially weight reduction, tires, rims, rim sizes and track width since they all considered when calculating the tune. If you still get not satisfactory tunes please contact me under fb@fiftyinch.com as I need more details.

Not work
Response from developer
The crash has been fixed with the latest update.
Latest update hasn’t worked
Revised review
1) I cannot find any way of making contact with the developers. I have tried on here, on X and on their own website but no email address, at least not one I can find. I’m not a Facebook user.
2) The last update was supposed to fix the issue of help links producing blank screens. It has improved but still virtually unreadable to the point of being useless.
3) All of the tunes I have tried seem to have very extreme settings, Anti Roll Bars set to maximum, Spring rates set to minimum, Suspension Geometry set to maximum plus or minus limits etc. In pretty much every case the car ends up worse than it was under the default tune provided by the game itself. At some level this applies to every car regardless of which class but the lower class cars seem to be more affected.
4) The website seems to claim that the app is progressive. I believe it’s meant to update itself with new car statistics as the car is upgraded, if I’ve understood this correctly, it doesn’t work.
I use the app on a standard iPhone 14 and a 3rd Gen iPad Pro, all of the above issues are present on both devices.
Seems like a work in progress
Forza horizon five
Response from developer
You can try the QuickTune app not Pro version, it’s completely free to tune all cars.
Yes indeed, worth it
Response from developer
Thank you very much!
Needs PS5 Support
Response from developer
PS5 and PC/Xbox versions are identical in terms of content and cars. What car are you missing parts for?
Disappointed
Response from developer
I‘m not aware that you contacted me through fb@fiftyinch.com. Sorry to hear that it didn’t work out for you. You can contact me anytime via above stated email (which is also visible in the AppStore) if you do have questions though.
Worth buying
Response from developer
Thanks a lot!
