What GraphLock does
GraphLock is a cross-platform mobile and web application that transforms smartphones into scientific, graphing, matrix, statistics, and time-value-of-money calculators with a patent-pending Lockdown Mode designed for classroom and exam use. The Lockdown Mode uses native device APIs (Guided Access on iOS, Pin App on Android) to disable calls, texts, notifications, and internet access, leaving only the calculator and an emergency-call button visible, while alerting session administrators to any attempt to exit. A complementary "Just Lock Me Mode" allows students to self-impose the same restrictions for distraction-free study. The product is available as a native iOS app, Android app, and web app at graphlockapp.com.
The company's core technology consists of a unified calculator engine and an exam-integrity layer built on top of operating-system-level device controls, with a teacher-side monitoring platform that supports real-time class session management, per-class feature customization, and a chat feature for distributing graphs, data sets, and PDFs. GraphLock serves four primary user tiers — Teachers/Proctors (free), Students ($4.99/year), Parents ($1.99/year), and Schools ($4.99/student/year via site licensing with Apple Volume Purchase Program support). The go-to-market mixes product-led freemium distribution through the App Store and Google Play, direct licensing sales to schools, community-led STEM outreach (math camps, mentoring), and channel partnerships — notably a 2017 integration with Proctorio that embeds GraphLock's Mobile Lock into automated online proctoring workflows.
GraphLock Inc. is a privately held, founder-owned company headquartered in Coolidge, Arizona, with its user agreement governed by New York law. The company was founded in 2015 (one source) or 2016 (firmographics) by Mallory Dyer, a former Central Arizona College mathematics professor, alongside co-founder Joshua Dyer (COO) and Chief Product & Technology Officer Vijayant Kanwar.

GraphLock competitors and assessment
Company assessmentOthers
- Proctorio: Automated online proctoring partner that embeds GraphLock's Mobile Lock technology. Ecosystem participant rather than direct competitor; relevant for channel and product integration benchmarking.
Direct peers
- Wolfram Alpha: Computational knowledge engine with strong graphing, statistics, and matrix capabilities. Comparable on the calculator surface, positioned more for higher-ed STEM than K–12 exam integrity.
- Desmos: Free mobile and web graphing/scientific calculator widely adopted in U.S. classrooms. Directly comparable calculator functionality to GraphLock, though it lacks a patent-pending Lockdown Mode for exam integrity.
- GeoGebra: Cross-platform math tool (graphing, geometry, statistics) used in K–12 and higher education. Overlaps GraphLock on graphing/scientific calculation; differentiated by broader math content suite rather than exam lockdown.
- Respondus (LockDown Browser): Browser-based assessment lockdown tool widely deployed in LMS environments. Closest direct peer for the Lockdown Mode concept, though focused on desktop browsers rather than mobile calculator lockdown.
Broad incumbents
- McGraw-Hill Education: Major educational content and EdTech provider with assessment and adaptive learning tools. Broad incumbent that competes for district wallet share alongside GraphLock in math classrooms.
- Hewlett-Packard (HP Calculators): Long-standing graphing calculator line (HP Prime) used in higher-ed STEM. Comparable hardware substitute and potential institutional procurement competitor.
- Casio: Established graphing/scientific calculator manufacturer (fx-CG, ClassPad). Represents the incumbent hardware ecosystem against which GraphLock positions its $4.99/year subscription.
- Texas Instruments: Dominant incumbent in K–12/college graphing calculators (TI-84, TI-Nspire). The primary incumbent GraphLock is positioned to displace on cost and smartphone-native UX.
Emerging players
- Honorlock: Online proctoring platform with mobile-device detection and secondary lockdown tooling. Comparable to GraphLock's Proctorio integration, targeting the same proctored-exam use case.
