Every comparison links to its source

The best comparisons sound made up. That is a problem, because the ones that sound made up are exactly the ones a reader stops trusting — and once one line is suspect, the whole app is.

So the rule is simple and it is not negotiable: nothing is invented. Every comparison is a real measurement drawn from Wikidata and hand-curated public sources, and every one opens its source from inside the app. If a line sounds absurd, it is still true, and you can go and check it in two taps.

What that costs

Quite a lot, honestly. Sourcing each fact is slower than writing one, and it rules out a large category of lines that would have been funnier than anything that survived. A comparison that cannot be backed up does not go in, however well it reads.

It also constrains the numbers themselves. The heaviest deadlift ever pulled is 1,124 pounds — a record with a date, a venue and a name attached. It would be easy to round that to a friendlier figure. Rounding it would make the app slightly better to read and considerably less worth reading.

Why the tap matters

A citation nobody can follow is decoration. Putting the source one tap away changes what the app is claiming: not “trust us” but “here is where this came from, decide for yourself”.

In practice most people tap once or twice, satisfy themselves the numbers are real, and never check again. That is the correct outcome. The link is not there to be used constantly — it is there so that the one time you genuinely doubt a line, the answer is immediate.
