Jobulator is gone. Here’s how substitute teachers get job alerts now.

If you subbed for more than a few years, you probably paid for Jobulator. It sat in the corner of your screen or on your phone, chirped when a job appeared on your Frontline board, and for a lot of subs it was the difference between working three days a week and five. Then it went away.

This guide covers what happened, what Frontline offers instead, what the third-party alert apps do and don’t do, and the part nobody says plainly: an alert is not a job. Here is how to think about the whole landscape in 2026.

What Jobulator was, and when it ended

Jobulator was Frontline’s own paid notification tool for substitutes, around since 2009. For roughly $40 a year it watched your Absence Management (the system many of us still call Aesop) job board and alerted you the moment a new job appeared. You still had to open the job and accept it, but you found out fast, and finding out fast was most of the battle.

Frontline announced a sunset in 2024. New accounts stopped, and the app was fully retired on December 31, 2024. Existing subscribers could use it until that date. If you search for it today, you find the shutdown notice and a pointer to the free Frontline Mobile app.

The official replacement: the free Frontline Mobile app

Frontline moved substitute job notifications into its general mobile app, the same one districts use for absences and time. It is free, and for most subs it is the first thing to set up.

• Job notifications. When a job you are qualified for is posted, the app sends a push notification. There is a sound setting so you can hear it, which was the feature Jobulator users missed most.
• Accepting from the app. Tap the notification, open the job, accept. Same steps as the website.
• Phone settings matter. Both Android and iOS have battery and notification settings that silently delay or drop app notifications. Frontline publishes a settings checklist for each platform. If your alerts feel late, that checklist is the first place to look.

What the app does not do is change the fundamental deal. The notification goes to every qualified sub the district allows to see that job, at roughly the same moment. Everyone hears the chime. One person gets the job.

Third-party alert apps

Independent services filled the gap Jobulator left, and some existed alongside it for years. SubAlert and SubSidekick are the best known. They log in to your Frontline account on their servers, check your board on a schedule (SubAlert says every 60 seconds), and notify you by app, text, phone call, desktop alert or email. Prices run about $5 to $7 a month.

They are useful, and they are honest about their limit: they alert, you accept. SubAlert’s own description of the experience is that when many subs are getting the same alert at once, who books the job often comes down to luck and a split second.

The uncomfortable truth about alerts

Every alert tool, Jobulator included, solves the problem of knowing. None of them solve the problem of getting. The Frontline board is first-come, first-served. In districts with a healthy sub pool, a desirable full-day job at a good school is routinely gone inside a minute of posting, sometimes inside thirty seconds. That is the time it takes to hear a chime, unlock your phone, open the app, read the job and tap accept, and it assumes you were not driving, teaching, or asleep.

We wrote a separate guide on why jobs disappear so fast. The short version: you are not competing with subs refreshing a web page anymore. You are competing with alert apps and, increasingly, with automation.

The other approach: have the job accepted for you

Sub Concierge is what we built after losing enough of those races. Instead of alerting you, it accepts the job for you. You connect your own Frontline account, then write your rules in plain English, the way you would tell a friend:

“Any full-day job at Lincoln, Washington or Jefferson Elementary. Nothing before 8 AM. No SPED. Never on Wednesdays. Text me about anything else that’s at least four hours.”

Your Concierge watches the board every few seconds, all day and all night, and when a posting matches, it accepts it within seconds and texts you the confirmation. Jobs you did not pre-authorize can still come to you as a text, the way an alert app would, so you decide. Everything runs on your own account, following only the instructions you gave.

It is not free like the Frontline app, and it is not the right tool for a sub who only wants one or two days a month and enjoys picking. It is for subs who know exactly what they want and are tired of watching it go to someone else.

Side by side

What we would do as a sub in 2026

1. Install the free Frontline Mobile app, turn on sounds, and go through Frontline’s phone-settings checklist. This costs nothing and catches the slow-moving jobs.
2. Get on preferred lists at the schools you like. Nothing beats a teacher requesting you by name. Our guide on getting more sub jobs covers how.
3. If you keep losing the jobs you want to faster fingers, decide whether you want a better alert or no race at all. That is the real choice between an alert app and a Concierge.
