Tedekaku makes the to-do list a sheet of handwriting

Field notes

Tedekaku treats handwriting strokes as the underlying data rather than converting them into typed tasks. The current Todo app accepts input from a finger, stylus, or mouse, keeps work on the device, and can operate offline after its first opening. Its stated performance target caps pen delay at 30 milliseconds. Cross-device synchronization and export are explicitly unfinished, while the broader project lists six planned or existing handwriting applications on the same foundation.
