Makes beautiful daily, weekly, monthly, and yearly charts.
Looks good on tiny phones and big tablets.
Has import and export features - no data lock-in.
The data shown in the screenshots is my actual data, most of which was collected with the desktop version of BlubberPatrol. And yes, I have daily data going back to 1993!
Notice that I have kept my weight between 152-155 for the last 10 years. Staying focused and vigilant is what it takes, and looking at a chart each morning keeps you aware of the trend.
