How Big? Guess the Size downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
52/100
faster than 53% of Games apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About How Big? Guess the Size
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
WATCH YOUR PROGRESS
• Earn XP, complete daily goals and unlock 34 achievements
• Build your Size Atlas and discover facts about the objects you meet
• Personalize your game with unlockable styles
• Compare results online, join weekly leagues and use Game Center leaderboards
MADE FOR QUICK ROUNDS
• Separate Daily, Games, Profile and Settings tabs
• One-handed controls, light and dark mode, iPhone and iPad support
• Core gameplay works offline; online comparisons, leagues and ads need a connection
• No account required to play
Ads appear between levels or surviving rounds. A one-time Remove ads purchase removes automatic interstitials. Optional rewarded videos remain available when you choose a bonus or a continuation. Purchases can be restored in Settings.
