A .taskpaper file is a text file. Projects are lines ending in a colon, tasks are lines starting with a dash, tags are @words. The app renders that file cleanly, folds sections you are not working on, and filters it with queries like @due and not @done. Underneath, the file stays readable in TextEdit, in vim, in whatever text editor exists in 2040.
That is the whole argument, and it is the right one if you have ever watched a task app shut down and take your lists with it. Sync is your file service's problem: iCloud Drive, Dropbox, a Git repo if you are that sort of person. There is no account and nothing to cancel.
What $24.99 does not buy is a promise about the future. Hog Bay sold TaskPaper 2 and TaskPaper 3 as separate paid apps and publishes no upgrade policy, so assume a version 4 would be another purchase. Present-day development is maintenance: the November 2025 release fixed a crash on macOS 26.1 rather than adding anything.
Do not buy it if you need a phone app you enjoy using. There is no official iOS version, and editing the raw file in a third-party editor works but is not pleasant. Do not buy it for shared lists, reminders you can rely on, or a calendar view either — it does none of that, deliberately.
