We’ve just released an update to Done, our iPhone to do list, which hopefully fixes a bug that a couple of people (with very long lists) were having.
Although we beta test everything very carefully before we release it, sometimes users find problems that we’ve missed, or more frustratingly, can replicate here. If anybody is still having any problems, please contact us and let us know – specifically if the app is crashing when you edit the list that an item belongs to.
