Doubtful
2026–present
A little space for what matters.
A quieter task app for iPhone and iPad. Keep up to three tasks in focus, and give everything else its own place.
Three boards. Room to change your mind.
Drag cards between Solving, Postponing and Uncontrolled.
Small steps, on your terms.
Finish the required steps to complete a task. Optional steps stay optional.
Pick up on another device.
Keep the same boards on iPhone and iPad with iCloud sync.
From idea to release
I developed my own app in Swift and released it on the App Store.
Product testing
I applied my QA experience throughout — from defining requirements and user workflows to functional and regression testing and usability assessment. I explored edge cases, reproduced and documented bugs in the simulator and on physical devices.
Fixes and automated tests
I defined tasks to fix bugs and refined the app in Xcode with AI assistance. I tracked task completion, verified the fixes and expanded the unit and UI test suites.
