One tracker for every application, including jobs you found somewhere else entirely.
Go to /jobs (or Career → Opportunities) and select My Job Hunt.
Applications made on the platform appear automatically. For a job found elsewhere, paste the posting URL and the details are detected where possible.
Update each row as things progress, so the tracker reflects reality rather than the day you started.
Applications that have gone quiet are flagged, and your companion can help draft a follow-up that does not sound desperate.
Open Track applications in My Job Hunt in the app (sign-in required).
