SubAlert review
A substitute-focused service for monitoring openings, filtering alerts, and booking jobs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SubAlert helps substitute teachers monitor and book open assignments from connected district accounts. It checks for openings every 60 seconds, applies user-defined job filters, and sends alerts through the selected channels. Substitutes can review available and scheduled jobs, see teacher notes and job details, reject unwanted assignments, and get GPS directions. Its substitute-facing scope makes it relevant to people tracking work across districts, rather than administrators managing absences.
Pricing is monthly, with a 21-day free trial and two paid plans. The App, desktop and email alerts plan costs $4.95 per month and includes those three alert types. For $6.95 per month, the Phone, text, app, desktop and email alerts plan adds phone-call and text alerts. Both plans support job alerts; the broader alert mix may suit substitutes who want assignments delivered beyond app, desktop, and email. Booking is available from alerts or the app, while scheduled jobs can sync with device calendars and Google Calendar.
SubAlert connects with Frontline Education Absence Management (formerly Aesop), Aesop Online, Jobulator, Kelly Educational Staffing, Kelly Services, and Source4Teachers. It is available through web accounts and iOS and Android apps, with multiple district accounts in one place. That ecosystem fit matters: the service relies on connected placement systems to surface assignments, rather than serving as a complete district absence-management product. Substitutes seeking timely openings and a way to book them may find its focus useful; districts needing absence entry or payroll export should look for a broader system.
