Fixes a bug that could reset your progress when the app opened straight on an incident, for example from a link or after Android restored the app. Also: incident mode names, exam notes and the Sandbox header are no longer cut off on small phones, Sandbox commands answer faster on slower phones, the side menu shows the open tab when the phone is on its side, quizzes leave room for the question in landscape, and buttons use the same capitalisation everywhere.
DevOps practice: Linux terminal labs, incident response and cert exam prep.
Learn DevOps by diagnosing realistic failures instead of memorizing theory. FixOps turns Linux, cloud operations, and site reliability engineering concepts into guided practice. Work through concise lessons, use an interactive simulated terminal, investigate incident evidence, and verify each recovery step in one focused learning experience. BUILD PRACTICAL DEVOPS SKILLS • Follow structured learning paths for Linux, DevOps, and SRE fundamentals • Practice common commands in a safe simulated terminal • Check your understanding with quick quizzes and explanations • Save notes and bookmarks so important concepts are easy to revisit TRAIN FOR INCIDENT RESPONSE • Diagnose realistic service and infrastructure failures • Inspect symptoms, logs, and clues before choosing a fix • Run commands and verify whether the system has recovered • Progress through increasingly demanding incident campaigns • Resume saved drafts without losing your investigation PREPARE FOR CERTIFICATION EXAMS • Practise for 22 exams across AWS, Azure, Google Cloud, Kubernetes, Terraform, GitHub and Linux • Read why each option is right or wrong after every question • Take timed mock exams weighted like the official blueprint • Work hands-on tasks for CKA, CKAD, CKS and LFCS in a simulator that grades the result • Start every exam with a free diagnostic or sample lab. FixOps Pro, a subscription, unlocks the full question banks; lessons, incidents, the terminal and the manual stay free KEEP YOUR PROGRESS Track completed lessons, quiz results, XP, streaks, badges, and unlocked challenges. Sign in with Google or email to sync supported account data, or start quickly with guest access. DESIGNED FOR LEARNING SAFELY The FixOps terminal is a simulation built for practice. It does not connect to a live server or execute commands on your device. You can experiment, reset a session, review command history, and learn from mistakes without risking production infrastructure. FixOps is useful for aspiring DevOps engineers, Linux learners, cloud practitioners, SRE candidates, and working engineers who want repeatable incident-response practice. Install FixOps and start with a guided Linux lesson, an incident lab or a free exam diagnostic. Practice questions and labs are written by FixOps.
