Charlie and the team are awesome. This is a great app with a streamlined UI for everything you need with inventories!

It doesn't have all of the bells and whistles some other apps may have. However, it is extremely easy to use to dissect and understand your data. It's fast, detailed and clean - the UI is super smooth to use and it's beginner friendly. I would definitely recommend this to anyone, this is a powerful tool and the support is top-notch.
