GraphLock

与锁定模式科学和图形计算器在课堂和考试使用

GraphLock is the ONLY scientific and graphing calculator app designed to be used in classrooms and on exams due to its unique Lockdown mode!

This app will turn your device into the fast and powerful tool you need to succeed in your math, physics, science and engineering classes/exams. Plus you never have to carry a separate calculator again! GraphLock is designed for education, studying at home and test environments.

The unique Lockdown feature disables phone functions (calls, texts, notification, internet, etc.) and turns the device into a calculator until the timer runs out or the authority figure (Teacher, Parent, Proctor) unlocks the user.

NOTE: You can use the calculator while not in Lockdown anytime, anywhere. You don’t need the internet and your device functions as normal.

Teachers - are you struggling to keep students off their phones and on task during class?

* You can create a Lockdown session and set a timer, then your students can only access the calculator on their device, meaning: no texts, no calls, no internet, no other apps!

* The classroom monitoring platform allows teachers to create classes, start/stop lockdown sessions, customize the calculator, send chats to classes, and get alerted if a student tries to make an emergency call or force his/her way out of lockdown.

* There is also a proctor version ideal for Testing Centers.

Parents - do your children waste time on their phone instead of doing homework?

* Parents can use Lockdown on their children’s devices, taking homework time to a whole

new level!

Students - don’t want to spend over $100 on a scientific and graphing calculator?

* Students can simply download the calculator they need, on a device they already have,

and use at school for only $4.99 per year

LOCKDOWN MODE FEATURES:

* During Lockdown, a student can make an emergency call if needed, but the session

administrator will still be notified

* The teacher/parent/proctor will not be able to control the student’s device, nor have

access to anything on the device

* No distance restriction

Just Lock Me Mode:

* Use to avoid distractions - set a timer and put yourself in Lockdown
