A small magazine about things that claim to work
7 pieces
Shorter pieces. Something we noticed, tested briefly, and thought was worth writing down.
A note on geometry
From directly above, a bowl with two inches of rice looks identical to a bowl with four. This is not a software limitation and it will not be fixed.
A habit worth breaking
We searched twenty common foods across four apps and checked where the correct entry ranked. On crowd-sourced databases, position told us nothing at all.
A labelling rule
Ours, attributed, or the maker's own claim. Most product writing collapses the second and third, and that collapse is where readers get misled.
Sixty packets
Barcode scanning is presented as a solved problem. It is solved for recognising the code and not solved for what happens next.
Reading a benchmark
±1.1% does not mean your dinner will be within 1.1%. Here is what these numbers actually describe, and the three questions to ask of any of them.
An experiment on ourselves
Two of us weighed and recorded every item for seven days, then logged the same food normally. The gap between the two was larger than the gap between the best and worst app.
A one-minute check
Log one food, open the full breakdown, and count the numbers. What you find tells you more about the app than any review will.
