Vesper offers a simplistic user interface that focuses on both quick input and customizable organization, utilizing tags to group items into collections. As the app description states, Vesper allows users to organize and curate notes in "whatever way comes naturally."
MacStories has published a detailed review of Vesper, comparing it to several other note taking apps available:
Vesper is about collecting thoughts with minimal friction. And not about doing so with a certain specificity in the UI – say, Day One’s emphasis on journaling or TaskAgent’s notebook motif – but in a generalized manner that revolves around one key aspect: speed. I have pondered over the motivation behind Vesper for days, and I’ve concluded that Vesper doesn’t want to be the new Drafts or Day One – rather, its aim is on Apple’s Notes app. The way I see it, Q Branch didn’t want to make an app that identified itself with one facet of note-taking: they wanted one that could scale flexibly for a more generalized use. And this, I believe, has been accomplished quite well.In addition to offering tags for organizational purposes, Vesper also incorporates drag and drop functionality to allow users to rearrange notes and older notes can be archived with a swipe for storage to create an uncluttered inbox. Both the archive and notes that have been tagged and arranged can then be accessed from the sidebar.
The app supports photos in addition to text, along with an in-app browser. It does not, however, support syncing as it is currently limited to the iPhone.
Vesper can be downloaded from the App Store for $4.99. [Direct Link]
