Excellent

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.

The new version is harder to use

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.

Payment methods

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

Love this company

Please help the app is broken. Only header loads.

Great App, Even Better Supply Company

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.

Good app but needs some refinements

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.

Great app and company.

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.

Superior

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.

Incredible, simply the best!

Everything about McMaster Carr is exemplary.

Please add Apple Pay as a payment option.

Legendary app

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.

Once Great

McMaster Carr was once a great company. Used to be next day arrival. Now it’s hit or miss if you get your order. Not worth paying the outrageous prices when you can get it a 1/3 of the cost and actually get it the next day from Am*zon. And they carry just about everything McMaster does now. Guess they couldn’t keep up. No place to go but up I guess.

Superior app & service

I've been purchasing items from McMaster-Carr for decades. The shopping experience has always been first class, even before the app. With the app, I'm able to quickly narrow down the specific item I need and get it ordered. I'm relatively close to their warehouse so shipping is always just one day. Awesome.

It’s a great app if you have the eyes of a 12 year old.

There are only a handful of apps out there that do not allow the user to increase the font or text size. McMaster Carr is one of the few dinosaurs. That is correct, it will not increase the font size even in iOS 15. I have joined the team to review new versions, and frequently asked about the ability to increase the font size, and was told it was not in the plan. It’s an absolutely amazing company with an absolutely amazingly bad app; it just doesn’t make sense.

The next best thing to the paper catalog

Why am I not surprised that McMaster’s app is also excellent? For chumps like me who don’t merit a paper catalog, this is a great tool.

AMAZING AMAZING AMAZING!!!

Have been struggling building prototypes for my startups. This app has taught me everything I need to know to finalize my builds:)

The App and The Business Bravo

I have been a faithful and very satisfied customer for over 20 years, so I always trying to spread the good news to friends, family, and business partners about what a great source McMaster Carr is for all types of items. In the “Catalog only days” I used to “guard and protect” my copy but with the app which allows you to find or learn anything at anytime, I don’t need to protect and defend my copy or carry it with me. Plus everything is always in stock. Amazing if you ask me.

PAINFUL Search

Several months ago they changed the way that search and sorting works. This was a terrible downgrade that makes searching and drilling down into products far too time consuming and painful and we frankly do substantially less business with MC because of this.

Horrid is not a good definition

This is no faster than with safari browser. After installing it, it is next to impossible to uninstall. I like and use company a lot but loathe this app.

Latest update won’t load

Great app! Had a spell for a few weeks when it wouldn’t load, fixed now and back to normal!

Zero stars actually

There is no estimate of shipping costs before completion of purchase. I bought a $5 item and was charged $23 for shipping. Buyer beware.
