The user interface is very easy - you can quickly create memos with various options like text, images or audio notes that are saved in your "Clever Memos" folder which I find particularly helpful when collaborating remotely.
It supports multiple users and works seamlessly across different devices too. There's nothing really bad about this app either; all it needs now would be an integration option for Google Drive so we could easily access our documents from anywhere! This has been one of my favourite tools at work since its introduction as part of Salesforce.
