### 1/5 — No login

*2024-11-12, version 0.27.24*

I can’t even get past the login screen. The loading circle just sits there forever.

### 1/5 — Flex5? More Like FlexNot

*2024-10-14, version 0.27.24*

Out of every app or software title I've ever used, this is one of the worst. I would rather use Windows ME than this. Navigating US tax returns for an LLC, Sole Proprietorship, C-Corp or S-Corp is easier. 

Setting up the pages in this app is a cryptic trial and mostly error process. Buttons often disappear when switching in and out of using the phone's camera as a bar code scanner. 

So many features the desktop app has are just missing. Like it would be really nice to be able to look up available inventory from my phone while I'm standing in front of a stack of road cases in the warehouse, instead of having to either go into the office and look it up and walk back, or drag a computer cart all over the shop. 

At this point, since Flex is already web based, it would be better to just make it work with Safari for iOS or like millions of other people/companies just make the "app" a cute browser that only browses [yourcompanynamehere].flexrentalsolutions.com and formats it so it fits on screen.

### 1/5 — Pointless, Useless, Frustrating, and overall Embarassing

*2024-07-19, version 0.27.24*

Using this app equates to being thrown back to the stone ages. Can’t see a full list of quotes or contacts beyond what’s shown. how the list is populated is anyone’s guess, yet you can add a new contact.  Once added don’t think of utilizing that contact in any way, shape, or form.   Does this app equate to the results of having one person writing code on the overnight. So what is the contact box for, to have one believe there is actually a CRM component.  I guess the fees paid goes to the expenses in attending all the conferences, cause there is more use and interaction in a app for preschoolers then what’s going on in this app geared to industry professionals.

### 1/5 — Neglected and useless.

*2024-03-28, version 0.27.0*

Neglected app that is missing most features that would make it useful. It’s not possible to view documents that are not parts of warehouse workflows. Warehouse workflows are clunky and the app needs at bare minimum a ui update to account for changing form factors.

### 1/5 — Trash rental software

*2023-07-27*

Have a pull list open:  scan an item- item goes somewhere completely different.

Only way to get flex to behave how it should be default is to use “substitute line”, then it open one up to incorrect items being scanned.

So close to being useful.

### 1/5 — Completely broken

*2023-07-12, version 0.27.0*

This should be removed from the App Store. It is completely non-functional and the last update was three years ago. Do better, FLEX.

### 1/5 — Useless

*2023-06-12, version 0.27.0*

This app is basically useless, I can’t access the majority of the information that’s easily available available from a desktop

### 5/5 — Good

*2023-05-16*

Great
