    I think every asthmatic should have this. This has breathed new life into my previously sporadic asthma care. Start the app, plug in & blow, result explained & logged in the diary-done! Also, an option to make a note & view the graph. The only nit pick I have, is that the clear mouth piece could do with a slightly tighter fitting.
