March 18, 2026

This release includes minor fixes and enhancements.

User reviews

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.
