I've found a large and often depressing collection of platformers, puzzlers, clones and scams on the App Store, but this is the first time I've come across a handheld base-jumping game. Even so, it's not the originality of AaaaaAAaaaAAAaaAAAAaAAAAA!!! (I'll be kind from here on and refer to it as F=MXA) that I enjoy nearly as much as the fact it doesn't make me hate gyroscopic controls.
Whether or not you agree with the argument that "real" gaming - whatever that means - isn't possible on touch-screen devices, you can probably agree that gyroscopic motion control makes us all look like idiots as we wave our tablets and phones around as though they're possessed by an erratic ghost. Not so here.
Instead, F=MXA neatly sidesteps any issues by encouraging you to peer down at your iOS device and use gentle degrees of tilting motion to move your character around as they fall to ground. At worst you're going to just look like another daytime drinker on the London Underground, head and arms lolling gently between your legs, but at least you won't look like you're wrestling with an angry pigeon that's trying to take flight. You feel like you're manoeuvring rather than rattling.
