GraphLock is an application that gives the full functionality of a scientific and graphing calculator. GraphLock is designed to be used in testing environments due to its unique Lockdown feature that disables all phone functions (calls, texts, notifications) and turns the user’s phone solely into a calculator until Lockdown is turned off. GraphLock can also be used in non-lockdown mode where the user’s phone will function normally. With GraphLock, users will never have to carry around a calculator again!
