Worst App Ever
Title says it all. Battery killer, overheating phone, lag of about 10 seconds per click, Screen freeze etc. 30 mins work finished in 2:30 Hrs. Wish I could give 0 star.
NOT an improvement
Much could be improved, issues with price book glitching and jumping around, the camera function blacks out and requires restarting, doesn’t recognize barcodes for known coremark products either from the manufacturer or coremark itself, causes excess overheating and fast battery drain on multiple different models of device, can’t price check without starting a whole new order, requires a long loading time upon opening, doesn’t provide product pictures or logical product titles, among many other issues

Burning my phone
Just used the app for 5 minutes and my phone is burning hot! I also agree with the other review that the IU is horrible and we would prefer the old app back.
Needs Major Improvements
This app has too many bugs. My phone gets very hot while using it, which is frustrating. Another major issue is the barcode scanner—when I scan an item once, it often scans the same item 4 or 5 times automatically, causing duplicate entries and slowing down my work. The app also crashes occasionally and doesn’t run smoothly. Please fix these issues and improve the overall performance and stability of the app.

Battery Drain
7/1/26: The last update made this app worse. Battery drain in at 30% in 30 minutes. That’s 1% per minute and results in overheating of the iPhone 17 Pro and iPhone 17 Pro Max. This is unacceptable for any app. I’ll be making a complaint to Apple. As a developer they have an obligation to make your app as efficient as possible.
2/20/26: This app drains the iPhone 17 Pro battery at a rate of 12% in 30 minutes. This is 3x the amount compared to other apps or even Core-Mark’s previous application. For an example using Numbers and Spark email on the same device used 4% each in the same amount of usage time.

Review of app
After starting to use the Coremark app, I noticed that it significantly affects my phone’s performance. The device becomes noticeably warm during use, even with short sessions, and the battery drains much faster than expected.
This level of power consumption seems high compared to similar apps, and it impacts overall usability, especially for longer use. It may be related to background activity or optimization issues that need to be addressed.
I hope future updates improve performance efficiency, reduce overheating, and optimize battery usage so the app can run more smoothly without affecting the device.

Terrible optimization
Battery drainage is insane, its the only app I use that behaves this way. Scanning barcodes acts very weirdly and sometimes doesn’t see a barcode in plain sight. And the search engine works sometimes and other times it doesn’t do anything.
All orders are always combined, but I wish there was a way to create separate invoices.

Need to fix your app
The app works, but the battery drain is unacceptable. It consumes far too much power and noticeably reduces my phone’s battery life. Please optimize the app, as this issue seriously impacts the user experience.
Customer service
So my app on my work phone has not been working since April. I have emailed customer service almost everyday to try to get this problem fixed and they have stopped responding to me. They gave me a ticket number for when the issue is supposed to be fixed but I don’t have access to said ticket to check the status. Customer first is not putting customers first.

Garbage app
So bad so hard to find items. Misspelled and older coremark app can find with nice pictures, instead this garbage of app, no common sense… now even self scanned getbstuck must close app to make it works again every 5 munutes
Tag printer format needs to be fixed.
Hello,
The format for the tag needs to be fixed as the tags which we print are looking horrible.
The original price is printed in the bottom bar without the $ sign in front. The whole format is messed up.
The old app had a good format and easy of use, the new app needs a lot of work to reach to that point and in the pace its moving it might be few more years. Please expedite the user interface and experience so it’s easier for users and app is user-friendly. The search bar needs to be worked on and also the core promotion section is all gone.

Dumbest app by the dumbest

Retail account holder
Not a user friendly app. When you delete an item from your shopping cart or change qty, that item moves to all the way top on your cart list. So weird and error prone set up to order through an app.
Everything is more difficult
The search engine is a joke. You can’t type in the name of an item without it auto correcting to something that they don’t even carry. This whole app is very obviously made with AI and it’s not very user friendly or correlated to the product at all. Items that have been in the system forever now have some weird generated name that makes no sense. My orders take double the time to do now. Extremely disappointed! Also most of my tags don’t work anymore. As someone else said, this can only be seen as a test of patience. I hope some updates get made soon.
Also, being able to look at items without creating a new order would be awesome.

Old App is better
Been ordering from Core Mark for many years now and I have to say the previous app is way better. This new app you can’t even scan to check a simple price of an item without having to create a new order. Versus the old app it opens right up to the scanner wasting no time. Instead of creating a whole new app just make an update into the old app. We’ll see what happens but old app is far times better in every way.

Bad App
UI of the app is completely horrible. The app tends to order items which have been removed from the on going order. Items show removed on one phone then they’re randomly added back. Huge amounts of the $$$ loss and random items ordered.
Awful app
This is an awful app. I can’t believe they are making us use it. It’s so glitchy and doesn’t provide good information when ordering. Also I can’t find things anymore like I used to with ease. It’s making me seriously consider if I need to find a different company to go with. My sales rep thinks it’s trash as well.

Terrible optimization
This app is what it is. You do your store order from it. Problem is it cooks my phone. I loose 10%+ battery in 3 minutes with this app running. Screen gets darker and darker and phone gets hotter and hotter as I make my store order. A company of this scale should not be forcing its customers to use this terrible app.
