Just the one on amazon that’s about 20 quid the now
I think once u buy it and activate it you get a week or months free trial and then after that it’s like 25/30 for the years subscription , 30 bucks over the year is peanuts so that’s the option I went for , it means you can use it on other cars aswell , as many as you like infact
it can be used in iOS and Android
OBD11 pro I got a good few years ago, I think it was around the £50 mark , no yearly subscription charge
the app is android only , like Carista it comes with preset mods for your car , but to make a change is usually about 120 credits – that works out about £1
but the good thing is if you log into the app you get a free daily credit , so whether you are going to use it or not , just log in to obtain your free credit , they soon build up
OBD11 seems to be a little bit more refinfd than Carista and let’s you save the changes you have done and reverse it , incase you make an arse of things
both do more or less the same thing , one can do a few things the other can’t and vice versa
ive never had an issue with any of them or any time I’ve had the car back at the dealers , both can be used of family or friends cars too
so that’s why I went for both , relatively cheap and future proof as cars become more and more computerised ??
