About this app

How big is a moose next to a London bus? A T. rex next to a giraffe? You probably think you know.

How Big? puts two silhouettes on the same ground line. One is fixed. Resize the other until it looks right, then lock it in and see the real size next to your guess.

FIND YOUR NEXT CHALLENGE

• 991 campaign levels with 284 objects, from a chicken egg to countries and planets

• A Daily challenge with five rounds, a streak to grow and results to share

• Survival: keep scoring above the line — your first miss ends the run

• Higher or lower: compare matching dimensions as the choices get closer

• Line-up: put four objects in size order

• Choose Objects, Countries & islands or Cosmos for quick games, each with separate local records…

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
