### 2/5 — Are y’all new here

*2026-07-16, version 1.4*

How are we in 2026 and the lack of everything this app LACKS is crazy…why the district switched who knows, someone is probably sleeping with someone cuz that seems to be the norm in that district.

### 1/5 — Worse sub app

*2026-01-16, version 1.4*

Sadly my school district switched to Ready Sub.  It’s absolutely horrible. I’ve worked for the same district for 10 years. I averaged 3-4 days a week. Now, I’m rarely even called. You may question is it a “me thing”. Nope. I’ve heard the same feedback from many subs.  The schools know of this issue, they blame Ready Sub.  I’m hoping the district switch’s back to the old app, because this one is taking food out of kids mouth.  Thanks Ready Sub.

### 1/5 — Notifications never work.

*2026-01-08, version 1.4*

This whole website/app is so bad. I have it set up to give me notifications through the app, email, and text. I don’t get any notifications from the app and I only get texts/emails less half the time. I miss out on so many subbing opportunities because of the lack of notifications.

### 1/5 — Iphone app is primitive

*2025-10-03, version 1.4*

The Android app is more like The web app.. Iphone app is only 2 blank screens all available jobs and I'm requested jobs. Both apps aren't named the same. Nothing more than Lazyness.

### 1/5 — Terrible app

*2025-08-19, version 1.4*

This is the most fundamental basic app I have ever used. It has no functionality and no push notifications so I miss most jobs. It’s a pointless app and hinders my ability to choose sub assignments.

### 1/5 — Rural Sub

*2025-08-07, version 1.4*

This app is not in the least helpful. It isn’t even worth downloading. With so many people having g iPhones, the app needs to be updated to include iOS.

### 3/5 — Options

*2025-05-16, version 1.4*

Good app. There should be a feature that allows subs to filter selected schools and grade levels so that we don’t miss out on opportunities. Also the app should send notifications when there are jobs available.

### 5/5 — Options

*2025-04-26*

Good app. There should be a feature that allows subs to filter selected schools and grade levels so that we don’t miss out on opportunities

### 1/5 — Useless

*2025-03-03, version 1.4*

This app does not show a calendar for your accepted assignments. The only thing this app does is let you accept an assignment and everything else you have to do from the website. Why is this app even available?

### 1/5 — Wish my work didn’t use this app

*2025-02-25, version 1.4*

Does not function right won’t let you mark down days of absence very bad website
