I’ve used the free T-Charts iPhone app for a few years, and while it has some usability, I haven’t been very impressed overall. A good T-Sheet app needs to be way more full featured.
- Side by side T format display.
- Easily manage many lists.
- Easily create or edit list name.
- Easily create, edit, delete items.
- Fit a lot of items on screen, say 15-20.
- Option to show entire item, or truncate to fit on one line.
- Insert items above or below other items.
- Reorder items by drag and drop.
- Sort items by weighting.
- Changeable text size. For readability, or to fit more items on the screen.
- Sub-items that wrap up into their upper level items. Be able to collapse sub-items to simplify the list.
- Show or hide weighting.
