### 5/5 — Excellent

*2026-01-19*

Searching for what you need is easy. Deciding not to buy it all is hard. I don’t have to use this app often but when I do I find what I’m looking for quickly.

### 3/5 — The new version is harder to use

*2025-12-04*

The old version of this app had the navigation button to view history orders at the bottom of the screen, as compared to the new version at the top. This makes the app hard to use because fingers are closer the bottom of the screen holding a phone. Not the top, is app need re-optimized for phone use in the real world please.

### 1/5 — Payment methods

*2025-09-17, version 3.24.0*

Tried to add my payment method but it just stays loading indefinitely when I press save so I can’t place my order

### 4/5 — Love this company

*2025-09-08, version 3.24.0*

Please help the app is broken. Only header loads.

### 5/5 — Great App, Even Better Supply Company

*2024-06-29*

Every engineer should have this app for plant design/maintenance.   But it’s the company behind the app that is really special.  The best customer service you will ever experience.   Pick up a phone and call them.   You will get a live person who is knowledgeable and willing and able to help.

### 4/5 — Good app but needs some refinements

*2024-06-22*

The simple catalog layout and graphical interface is easy to understand and well categorized. It is similar to their website layout. 

However, the navigation in the app is a bit confusing at times. The navigation tools are at the bottom right of the  corner of the screen which is awkward locations. It also doesn’t work half the time. Every other app has it at the top left of the screen. The app could benefit from having a toolbar or ribbon for easier navigation. For every hardware folder you click on, it should make a new tab showing the category name every time one is clicked on. Some hardware items have many subcategories and it would be nice to see the path I used to get to a particular item. 

Some other things to note is it is a little buggy, like the screen would shift slightly for some reason. And occasionally it would freeze and not respond to touch, forcing me to restart the app and losing my progress searching for parts.

### 4/5 — Great app and company.

*2023-08-29, version 3.7*

Great, easy to use app and McMaster-Carr has Greta service. For me living in Pa and their warehouse being in Ohio, I get my orders the next day. My new go to for hardware.

### 5/5 — Superior

*2023-05-25, version 3.5.0*

Great customer service, straightforward, no nonsense, website! Love it. Most items arrived next day. McMaster Carr is what Granger wishes it could be. I’m always shocked at how few people know of this superior supply company.

### 5/5 — Incredible, simply the best!

*2023-03-23, version 3.5.0*

Everything about McMaster Carr is exemplary. 

Please add Apple Pay as a payment option.

### 5/5 — Legendary app

*2023-02-22, version 3.4.1*

This is how you make an app. Really amazing and even better than their legendary catalog. I only wish I lived near a distro center cause the shipping can be prohibitive for a hobbyist.
