About Simple Tuner Guide

2. Want to tune cars yourself, but don't know where to start?

3. With this app, you can give unique and personal touch to your cars, without loosing a sense of exploration, when someone just hands you a "perfect" tuning number.

Simple Tuner Guide Customer Insights

1. Beautiful job!!!!Very good should do a full pledge calculator.If you want an easy way to tune your suspension, this is it.Shiyttt, you just enter values.Невнятное описание функций и какие параметры нужно именно вводить (90% описаний вообще ссылаются на описание игры), также приложение не реагирует на ввод данных и НЕ выдает никаких результатов, крайне кривое творение.

2. The app (To my suprise), once downloaded does not ask for 1 single access into my phone & doesn't need any access either! Progress!!! This app is great for getting your Ride i.e. Springs, Dampeners, Roll Bars etc... Although it's not a full 'Gear&Car' tuner, it's still a great tool to have.

3. Well done to the Dev, keep growing ur app its good work WD TY !Wow! Was skeptical at first, but surprisingly this app really delivers! Not only works for Forza titles, but also for GT Sport, Project Cars and Assetto Corsa.

4. Used in conjunction with the in-game telemetry and the Gallium tutorials on YouTube this app has made setting up my cars so much clearer and easier.

5. Beforehand I was just using guesswork and getting pretty woeful setups as a result, but now I'm flying round the tracks.

6. Great job!Yeah, still love the simplicity.the more I study this app,the more I appreciate the creator.

7. I can't recommend this app enough 👍Quick & Easy + 100% Non-intrusive.

8. Epecially as its not got intrusive ads or a 'Pro' grift...Ahem! I meant a 'Pro' cost.

9. I'm completely new to tuning so it took a little bit of figuring out what to do in the app, but it soon became apparent.

10. In all honesty it's helped transform FH4 for the better for me.

11. 10/10.
