Estimated revenue

A model estimate with a likely range, not a reported figure.

No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.

How this estimate is made

Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.

Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.

Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.

Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.

Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

Watch the sand pour.

Every single grain moves for real — it falls, it piles, it slides. Drop one
block and thousands of colored grains stream in, the picture above breaks
apart, and the colors settle somewhere you never planned for.

Sand Fill is the oddly satisfying block puzzle where physics does the talking.

HOW TO PLAY

  • Look at the sand picture above — colors, shapes, layers.
  • Drag a block onto the grid below.
  • The block drinks up every grain that matches its color.
  • The rest of the sand collapses and resettles. Read it again.
  • Empty the whole picture before time runs out.

One finger. No tutorial needed. You'll get it in ten seconds.

IT'S THE PHYSICS THAT GETS YOU

This isn't sand-shaped decoration. Grains fall, stack, avalanche and mix.
Clear the red underneath and everything above comes down. Every stage is a
little collapse you set off yourself.

SPACE IS THE REAL PUZZLE

The grid below is small, and blocks come in awkward shapes. Park one badly
and you've stolen the room you needed three moves later. Strong players
don't place fast — they place last.

COLORS DON'T STAY PUT

Sand mixes as it falls. That clean band of blue turns speckled halfway down,
and now you have to dig for it. Bring your blocks to the sand instead of
waiting for the sand to come to you.

PUZZLES THAT KEEP CHANGING

  • Hidden blocks that won't show their color until you clear others
  • Frozen blocks locked behind ice
  • Layered blocks hiding a second color underneath
  • Sliding blocks that travel on one axis only
  • Locks and keys
  • A brand-new picture every single stage

WHEN YOU'RE STUCK

  • Freeze — stop the clock and think it through
  • Hammer — smash one block into single squares and spread them out
  • Magnet — pull every matching grain straight into one block

Save them. You'll want them later.

FEATURES

  • Real falling-sand physics, grain by grain
  • Simple one-finger drag controls
  • Colorful pictures to uncover
  • Shape and space planning that actually matters
  • Clear goals, quick stages, easy to pick up
  • No wrong way to start — just drop a block

Drop the block.
Watch it pour.
Clear every grain.
