Apple seems to be making the shift to larger iPhone displays, and while this is great for media consumption, it also tends to make one-handed usage a bit more challenging in most scenarios. This is precisely why iOS comes with an accessibility feature dubbed Reachability.
Despite how useful Reachability can be at times, its aesthetics sometimes leave a lot to be desired. With that in mind, iOS developer CydiaGeek created a new free jailbreak tweak called ReachabilitySheer to make the Reachability interface look both cleaner and nicer.
