Sorry for the slow reply, thought I was so far down the list people wouldn't be seeing it.
First - thanks for the feedback and discussion. Really useful insights.
You are correct in that the interface is the 'new' - and also that single codes are a poor way of input. The original reason for SMS was to interupt the user to actually get them to make a measurement. I've since changed that the interupt still comes as a message, but the input/logging is done through a full application. It also means that the application is more accessable for reviewing data, making changes, processing, etc - as you mention is an advantage for simple spreadsheets.
The advantage over a spreadsheet is trading some 'freedom' for easier analytics. I'm wanting to make quantified self more accessible for people without the skills (or maybe interest) to do data processing themselves.
Agreed that having a smartphone is probably a good assumption for the market.
