Kosshi Outliner

I love outliners. I love native Mac apps, and I love keeping my data on my computer, not in the cloud. This checks all the boxes, and is remarkably stable for a new app. I love the single file data base approach. This is as close as Mac has come to GrandView - still the best of them all. 

The iPad version has a little catching up to do with the Mac version, especially in find and filter, (the found items are highlighted, but sometimes are not seen in the window as you step through them, filter doesn’t always work) but I am sure that will be fixed soon. Kosshi has already surpassed the competition.
 The Desktop version is 5 stars and the iPad version is 3 stars, so I am giving it 4. Edit: I think the iPad problems were user error. I am changing this review to 5 stars. For my personal use, notes like OmniOutliner would make it perfect, but that is the only change (I won’t call it an improvement) I would like to see.

This app has a lot of potential. I love the design; it is kind of like an offline Workflowy, which is not a bad thing. The developer is accessible and responsive, and I have seen the app improve tremendously since I first got it. I am looking forward to watching it grow.

I used to use an online outliner that was subscription based and lacked end-to-end encryption, which I was never very happy about. It was great to find this app that supports huge outlines and syncs fast over iCloud between devices and is a one-time purchase. Thank you!
