It is good when it works. However, lately some jobs that I have available are showing up on Frontline, but NOT on the app and I am not always receiving alerts. This app was once very good and I could always rely on it. Now, it seems to be a hit or miss. UPDATE: They are going out of business at the end of the year because Frontline is ending their agreement with them. Good riddance. We shouldn't have to pay to work anyway!

Recently, the Frontline interface provided for third party apps to access substitute information had been intermittently having issues. This has now been ironed out. Please reach out to us here: support@subalert.com if you have any questions or if you are still having problems.

While the app is the only one that works with AESOP that shows your scheduled jobs, I can't schedule anything! I click on "book" and it always says that the job is already booked even though, when I open the same listing on Sub Assistant I am able to claim it! It might be the cheaper option but I would recommend spending the few extra bucks so you can actually book a job!

Sometimes an unavailable job stays listed in the Frontline Jobs tab, and when you trying book it, it comes back with an error message saying the job is no longer available.Usually this happens with jobs that are just temporarily unavailable - they usually allow someone to book them after a few minutes, which is why you may be noticing this!

Update on this app. I have used it for the three years I have subbed since my retirement. It has been great from the beginning. . I was able to respond to the requests immediately and book the sub jobs in the classrooms that I was comfortable in. I would highly recommend it to anyone who is considering subbing. I was able to receive phone calls, text messages and emails with the all the information for the jobs available. Awesome app. I have used this app for the last school and was very pleased with how well it worked. It worked out so well for scheduling days to work around any appointments I made. I look forward to using this app for the next school year too. So great to be able to customize my schedule and when I received alerts for upcoming jobs. The text alerts seem to work out best for me rather than the phone calls. Thanks for making subbing so easy.

What’s new

Notification improvements!
- Better formatting
- Now, when you successfully book a job from the notification, it will only clear *that single notification* instead of all of them. That way you can go back to your notifications to try booking another of the new jobs if you like.
- After a temporary error booking a job, the notification will still be around, so you can just click it again to try again.
