This app will use three tests to gauge the severity of Parkinson's. In the Static Spiral Test, the user must trace a spiral on the screen as stable as possible within 6 seconds. In the Dynamic Spiral Test, the user must trace another spiral on the screen as stable as possible within 6 seconds; however, the spiral will flash on and off to test the user's short-term memory of the location of the spiral. Lastly, in the Stability Test, the user must press on a specific part of the screen without moving their finger for 12 seconds, all while performing mental arithmetic, which could affect motor functionality.

The user also has access to the statistics regarding their progression of testing scores.

The last feature, also unique to MobiTest, is an Accessible Keyboard, drastically improving communication with someone who has speech impediments, a common yet overlooked result of Parkinson's Disease. To use the keyboard, one has to select a letter shown on the screen, and a list of words starting with that letter will show up.

It is used by a caretaker who would move their finger across the grid of the alphabet until prompted to stop on a letter by the user with a speech impediment. After selecting the letter, the caretaker would move their finger across the list of words that appear until prompted to stop again on the word that the user with a speech impediment wants to convey.
