App Description

GraphLock is an application that will turn a user's phone into a fully functioning scientific and graphing calculator. The calculator is simple to use, yet powerful. What sets it apart from other calculator apps is its unique Lockdown feature that disables all phone functions (calls, texts, notification, internet, etc.) and turns the user's device into a calculator until the time runs out or the authority figure (Teacher, Parent, Proctor) unlocks the user. Therefore, per school policy, GraphLock is designed to be used in the classroom and testing environments. GraphLock can also be used in non-lockdown mode where the users phone will function normally. GraphLock also ensures the user will not have to carry around a calculator separately from his/her phone anymore. Use it anytime, anywhere! With GraphLock, users will never have to carry around a calculator again!
