Make the App for Smartphones just like the App for Tablets.
On Tablets you can see both drivers at same time, manage both drivers at same time and you can use double kers for both drivers at same time.
On Smartphone you can't see both drivers at same time and you have to switch between them, you have to tap many times on the switch every lap just to manage the push levels and you can't use double kers for both drivers at same time.
It's like that on ALL tracks, phone players are HEAVILY penalized compared to tablet players.
Especially the Italian GP, which is all about DRS and KERS, a skilled phone player has to be really LUCKY to beat a just as skilled tablet player. 99% of times the tablet player wins it, otherwise you need to leave one driver behind by himself and just concentrate on one driver, if you wanna have a chance to win. I just lost a race in Italy (got P3-P4) just because my opponent used double kers to pull off and I couldn't reply to his move. I tried, in fact there is a way to use double kers on phone but it's too hard and tricky as you have to push kers, keep it pushed while switching to other driver and push kers again to use boost. But not only it's tricky, you also WASTE a lot of kers in the switching process, cause to stop the first driver kers you have to release the other driver kers, switch back to the first driver and push kers again to stop it. A total WASTE of kers and also very hard and tricky to make it work. I tried to reply to my opponent's move like that but I couldn't make it, wasted my kers and didn't manage to stay close to him, then obviously I gave up and took the P3-P4 for good. That's not fair.
Can't you just make the app like so you can rotate the phone and watch the race in landscape? So it shows both drivers at same time and you can just have the same possibilities as tablet players. Would that be too hard to make? This thing really drives me crazy everytime and makes me wanna play only in single car leagues just because of that. Did you ever take consideration of this thing? People who don't own/need a tablet can't buy one just to play iGP on equal terms with tablet players. And that makes the game unfair. And frustrating, if you play to win.
