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.

Tool for planning staged decompression dives for technical divers.

Supports open circuit and closed circuit rebreathers, multi-level and repetitive dives, nitrox, trimix, altitude adjustments, metric and imperial measurements.

Keeps track of gas consumption, OTUs and CNS. Per dive configurable ascent/descent rates, last stop/stop interval settings and RMV/MOR. Any combination of OC and CCR planning is possible (CCR dives with OC levels/deco etc.).

One tap access to lost-gas, bailout, deeper & longer contingency profiles.

Constantly displays updated plan details as changes are made, and uses color highlighting to suggest best mixes.

Dive plans can be stored in a bookmark folder for convenient reuse. Plans can also be exported via email or pasted into any other app.

Features both VPM-B (based on Erik C. Bakers work) with configurable conservatism and ZHL16-B with configurable gradient factors for calculating decompression profiles. Also supports VPM-B/GFS.

How the score works

Gap check · UK

Is this US chart app missing in UK?

Already on UK charts

It showed up on a UK chart in the last 30 days, so it is not a gap.

Store not checked yet

This is a candidate, not a verdict. Charts show at most 100 apps, so not charting does not mean no demand. Check the UK store before you decide.
