TaskDan is a task manager where you complete tasks by flicking cards upward into the completion zone. Instead of tapping a checkbox, send a finished task flying with your finger. TaskDan adds a satisfying physical gesture to the everyday act of getting things done. Create separate projects for work, household tasks, shopping, personal projects, or anything else. Swipe between projects and keep each set of tasks organized. Main Features ・Organize tasks by project ・Add, edit, and delete tasks ・Save a title and memo for each task ・Complete tasks with an upward flick ・Enjoy completion animations, sound, and haptic feedback ・See cards return to their original position when a flick is not completed ・Check the number of tasks completed today ・View completed tasks by date ・Undo completed tasks ・Back up your data ・Restore data from a backup file Task and project data is stored locally on your iPhone. No account registration is required, and the app can be used without an internet connection. Add a task, then flick its card upward. When the gesture has enough distance or speed, the card flies into the completion zone and the task is completed.

Verdict
The clearest difference is in-app purchases: Taskdan at none against Portside's 1. Taskdan also leads on iOS requirement (17.0 vs 26.0). On price, update cadence, ads and device support there is nothing between them.
