You bring up some relevant points -- we also have data from our first version, textWeight 1.0, and have used a number of the analyses and insights from our data, independent reports and surveys. Use of SMS texting is key here. To your point while some believe frequent weigh-ins are detrimental, there is published literature that supports improved outcomes with frequency of weigh ins, and textWeight 2.0 puts this totally in the hands of the user. As a user, you can configure number of days per week and time of day for text alerts.
I have to agree, overindulgence is generally unappreciated, Self Tapper at 5-7 texts per day may be overboard but that remains to be seen. textWeight also has a weight maintenance option to message and encourage users appropriately. All users receive motivation, support and encouragement based upon their personally defined challenge and latest weight entry. This along with the behavioral information they contribute and our continuous bidirectional dialoguing enables us to provide such encouragement.
This is unique to the healthcare space -- where well designed programs like Text4baby and Vaxtext push messages to survey and collect data to discover their impact.
To your point about filling a low cost niche, we call it providing access in healthcare, we have intentionally used SMS texting to allow for use by feature phones (current smart phone penetration is under 30%) and since being overweight and/or obese strikes across demographics we want to enable broad access to all we can help. There is not a CEO of a start up or Fortune 500 company who would dispute this.
