Good with a few bugs

The app is good. I can find what I need. Filtering is easy and effective. McMaster has the best web based catalog that I’ve used which I do a lot for work. This app I use for personal stuff. I took a star off because the checkout screen has some bugs. Even if my ship to address is showing it asks me to enter it. I can’t. I have to go back to the home screen then back to the order page to get it to show correctly and work. Same for the credit card entry. I’m using an iPad Pro with newest iOS.

Best App, Best Supplier Ever

McMaster-Carr is always there to answer your questions, even though it’s not often that you will have a question because their app and website are so neat, well organized and full of and relevant information that you may seek. As someone who is often looking for new ways to do things and finding new materials to work with, McMaster’s descriptions make that a breeze. Any item you view will almost always be described as though you are learning about it for the first time making it very simple to find what you’re looking for, when you don’t know what you’re looking for is called or looks like! Shipping is also very reasonable and once you have a feel for their rates you will not second guess how much they are going to charge.

Thank you McMaster for great service over the years!

Great supplier, poor image handling

I find the app a little clearer to use than their website, but they treat images as non-zoomable static size. I find myself constantly going back to their web site (another: why does it offer to copy the web link but not also offer to just GO to the web link. Makes what could be a single operation into copy, switch apps to safari, create a new tab, paste. Just have a 4th button to go there!) so that I can see the exact same information, except that when I pinch and zoom on the image, it does.

If they wrote this in Xcode like they should have, these changes would be trivial to make. Hope to see them soon.

Hi FM_M, thanks for sharing your thoughts on our app. We're currently working on making it possible to pinch and zoom in on the image, along with copying and saving the image. This new feature should come out within the next month or two.
