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.

About this app

Text from the App Store listing.

Koala is the ultimate pocket-sized sampler. Record anything with your phone's mic or load your own sounds. Use Koala to create beats with those samples, add effects and create a track!

Koala's super intuitive interface helps you make a track in a flash - there is no brake pedal. You can also resample the output of the app back into the input, through the effects, so the sonic possibilities are endless.

Koala's design focuses totally on making the music-making process instant, keeping you in the flow and keeping it fun, not getting bogged down by pages of parameters and micro-editing.

"Been putting that $4 koala sampler to good use lately. Undeniably great tool that puts some of these expensive beat boxes to shame. A must cop."

What’s new

Release notes for the latest version, as written by the developer.

v2.0.15
  • Automation for bus effects, mixer channels and plug-in synths and effects
  • New "Same pad mapping for all banks" option in MIDI settings - map the 16 pads once and the selected bank decides which pads your notes play. The bank selector can be MIDI mapped too. Switch it off and each of the 64 pads keeps its own mapping, as before
  • MIDI map mode can now be toggled from the QWERTY keyboard (default key `;`) or from a mapped MIDI control
  • iPhone Duo support
  • Looper recording (swipe down on a pad) now starts and stops cleanly on the bar line, including when you stop just after the bar
  • Pad to MIDI note mapping is now a fixed 4x4 layout whatever the window shape, so a sequence recorded with the AUv3 open in portrait plays back on the right pads once the window is closed
  • Fixed grid keyboard getting stuck after a scale change near the end of the range
  • Appending sequences now copies their parameter automation too
