Best Outliner I’ve Used

This is a brilliant outliner app. I use outlining a lot for various purposes and I’ve found Kosshi to be the smoothest experience. The integration between Mac and iOS versions is fantastic. I mainly write outlines on my Mac, but view/use many outlines on my iPhone. Being able to easily navigate on the phone, and add content as needed, is done in a thoughtful and intuitive way. Plus the app developer keeps adding important new features. Put simply: best outliner I’ve ever used.

Thank you for using Kosshi! I’m glad you’re finding it useful. I’ll keep working to make it easy to use across your Apple devices.

Great start

This is an excellent app so far. I’m excited to see where it goes over the next few months. It’s already entirely useable and really fills a space in the iOS and Mac OS cross compatible offline outline apps that no other app fills currently.

Top Notch 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.

Great potential

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.

Thank you for using Kosshi and for your kind words! I’m still working on many more updates, and I hope you’ll enjoy watching it grow.

Excellent outliner

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!

Thank you for the thoughtful review! I’m glad to hear you’re enjoying Kosshi. Reviews like this encourage me to keep improving Kosshi. Since you mentioned end-to-end encryption, I’d also like to add a note about privacy. Kosshi’s synced outline text uses CloudKit’s standard data protection, but is not currently protected by end-to-end encryption through Apple’s Advanced Data Protection. I’ve also added this information to the Kosshi website. https://kosshi.app/data-privacy
