LockDown Browser is a custom browser that locks down the exam environment within specific learning and assessment systems. When LockDown Browser is used during an online exam, you are unable to go to other URLs, switch applications, take screenshots, copy questions or print. It essentially locks you into the exam until it’s submitted for grading. Important: This application can only be used with the Respondus Monitor proctoring system if your instructor has enabled the use of an iPad for the exam. If your instructor hasn't enabled the use of an iPad for the exam, you will be unable to use this application with it. While LockDown Browser isn’t the most exciting app available, it does make online assessments possible. And, hey, you can download it for free. This is NOT a limited-feature version and there are NO advertisements of any type.

SafeExamBrowser (SEB) is a secure kiosk web browser environment used to carry out e-assessments that run on exam servers. SEB opens a web browser without an address and search bar, loads a pre-configured webpage and locks an iPad (or iPhone or iPod Touch) into an assessment kiosk mode. This mode prevents students from switching to other apps (unless additional permitted apps are configured), accessing websites and communicating with other students during an exam. SEB enables secure exams on unmanaged iOS devices like students' own iPads as well as on iOS devices owned and managed by an institution. SEB doesn't use a centralized server or cloud service; it can be configured with an API, configuration files, links and QR codes. It can be used with most web-based quiz and e-assessment systems. For improved security and usability, some exam systems provide additional built-in support for SEB. Currently, SEB integrates especially well with learning management systems (LMS) such as Moodle, OpenOlat, ILIAS and with several non-commercial and commercial exam systems, such as Inspera Assessment, Dugga, Exam.net, EvaExam and Ans. SEB uses one of the single app modes provided by iOS. After an exam is submitted, SEB can automatically end the app self-lock assessment mode (an exam invigilator could also use a quit password to end the SEB exam session and unlock the device if necessary). SEB features an optional Dock displaying buttons for various commands. Instead or in addition, a left slider menu shows a list of open browser tabs and commands which can be used to (if enabled in settings) quit an exam session, jump back to the start page of an exam, reload a web page, and navigate back/forward in the browsing history. SEB for iOS uses the same format for encrypted .seb configuration files as the SEB versions for other platforms. Those config files allow to individually configure SEB to display the start page of an exam system or an exam portal page with a list of links to current exams. If SEB for iOS is installed using a mobile device management (MDM) system, its initial configuration can easily be deployed using the "MDM Managed Configuration" feature. You can also directly start an exam with an individual configuration in SEB for iOS using a special config hyperlink. This link can be opened by examinees from Safari, Mail or a messenger app. In addition, you can use QR codes containing SEB links or even full, individual configurations. An exam can directly be started in SEB by using the iOS Camera app or the built-in QR code scanner. SEB also works together with Apple Classroom, teachers can start individually configured exams on all student devices. See https://safeexambrowser.org/ios for more information. SafeExamBrowser for iOS was developed by Daniel R. Schneider, ETH Zurich, IT Services, based on the original idea of Safe Exam Browser by Stefan Schneider, University of Giessen Project concept: Thomas Piendl, Daniel R. Schneider, Damian Büchel, Andreas Hefti, Nadim Ritter, Dirk Bauer, Michael Kern, Kai Reuter, Tobias Halbherr, Karsten Burger, Marco Lehre, Brigitte Schmucki, Oliver Rahs. Safe Exam Browser is released as freeware. The code is subject to the Mozilla Public License Version 1.1 (the "License"); you may only use these files in compliance with the License.

Important parts of this project have been carried out as part of the program "AAA/SWITCH – e-Infrastructure for e-Science" led by SWITCH, the Swiss National Research and Education Network and the cooperative project "Learning Infrastructure" (part of the CRUS program "Information scientifique: accès, traitement et sauvegarde") coordinated by SWITCH, and was supported by funds from the ETH Board and the State Secretariat for Education, Research and Innovation (SERI).

Verdict

The call

The clearest difference is rating: SafeExamBrowser at 1.6 against LockDown Browser's 1.2. SafeExamBrowser also leads on device support (3 vs 1) and iOS requirement (12.0 vs 15.0). LockDown Browser's advantage is ratings volume (3.9K vs 46) and update cadence (every 5 weeks vs every 3 months). On price, review sentiment, ads and in-app purchases there is nothing between them.
