Very good app, just got better
The latest version is a solid improvement of what was already a simple but very useful app. My biggest gripe about the original was that the graph of a nights sleep was too small on the iPhone screen. This is fixed in the latest version, which lets you see an individual night as a long vertical bar, with details of the night now readable. Another refinement is that awake time is now shown as a distinct entry on the graph, not lumped in with restless time as before.
