Verdict

The call

The clearest difference is rating: DigiKey at 4.7 against Mouser's 2.4. DigiKey also leads on review sentiment (51% vs 18%) and ratings volume (3.4K vs 34). Mouser's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.

  • 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.
  • This app immediately logs you out when you go to “my orders”, basically rendering the core functionality completely useless
  • Crashes when searching
  • Carts do not sync with website
  • The issues stated in the old reviews appear to have been fixed.
  • The app cannot find Mouser part numbers that are immediately found using a desktop computer.
  • App crashes every time I try to view component data sheets or documentation.
  • Newest Products links in the iOS app do not work. They just bring you to the main menu.
  • Can't access my cart in latest update.
  • 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.
  • 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.
  • If you want to buy a part you have to go to the Mouser web site.
  • The app isn't iOS 7 optimized and really is only their website in a browser, aside from the scanner.
  • Part number search takes you to a page in the catalog, instead of to the product description or part spec sheet.
