With the ever-growing smartphone display sizes since 2013, chances are most of smartphone or “phablet” users have difficulty using the whole area of the screen with a single hand. The Android application or app presented in this report aims to solve or at least lighten this burden using a mapped touch area on the bottom reachable part of the screen. This not only makes hard elements more easily reachable, but also helps the user avoid uncomfortable or risky smartphone grabs while in movement. Testing done with 10 people and a 6” modern device will show the impact of this implementation. The test subjects indicate a lighter use after getting over the training phase, which has a fast but steep learning curve.
