Read the reviews… Immediately deleted the app

While the app was installing I thought maybe I should check the reviews knowing the website was its own special place on the internet. F’n hilarious! “Useless, pointless, comically bad” I immediately deleted the app. Never even opened it. 😂

Please fix broken app

Comically bad. The barcode scanned does not work. Anything you scan brings up a totally wrong product.

Username is fine, but email doesn’t work for login

The barcode scanned does not work. Anything you scan brings up a totally wrong product.

Bug

Can’t be synced to user account

Bug

Can’t login to mouser account

Bug

Sur les outils, les conversion sont impossibles avec les décimales car sur le pavé numérique est afficher une virgule(,) alors que le l’application ne fonctionne qu’avec le point.

Bug

This app immediately logs you out when you go to “my orders”, basically rendering the core functionality completely useless

Bug

Crashes when searching

Bug

Carts do not sync with website

Bug

The issues stated in the old reviews appear to have been fixed.

Bug

The app cannot find Mouser part numbers that are immediately found using a desktop computer.

Bug

App crashes every time I try to view component data sheets or documentation.

Bug

Newest Products links in the iOS app do not work. They just bring you to the main menu.

Bug

Can't access my cart in latest update.

Bug

When you have so many products - it takes considerable effort to pare down to what you need. Then start adding to the cart. One mistaken press and you are doing it all over. It’s maddening.

Bug

The app kind of opens the website within itself but also has a few of its own buttons so you’re never quite sure were you’re meant to click.

Bug

If you want to buy a part you have to go to the Mouser web site.

Bug

The app isn't iOS 7 optimized and really is only their website in a browser, aside from the scanner.

Bug

Part number search takes you to a page in the catalog, instead of to the product description or part spec sheet.
