this could be me but
1. app: when I just want to look at my graph I can't seem to do it unless a hr monitor is present
2. on the app it seems to show the effect of the FIRST of today's reading whereas the WEB READINESS thing seems to show the last of TODAY's readings - I think the web is right and the app wrong. eg if I take a reading and then another within an hour or less then I would expect the lowest values to be used.
neither of these are significantly affecting my life in any way so not urgent :-)
