The quality of the in app graphics is what attracted me to your iphone app. Many of the competing apps have very ugly and garish colours particularly when displaying graphs.
Just a couple of suggestions to improve the usability of your graph of BG results:
- make the y axis variable (set by user) or optimised to the data that is being presented. If a user's BG values are pretty stable most of the graph is unused and the entries are very close together. This makes it more difficult to interpret small variations.
- add an option to switch between the current display of low/average/high and an event based display. If the user tests at a standard time or event (eg before breakfast) it would be helpful to see how the BG values are changing at that event from day to day.
Thanks again for a great app
