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.
Welcome to 10 Downing Street. You're the new Prime Minister of the United Kingdom in this satirical strategy game for people who think they could do better. Try not to get sacked.
A crisis lands on your desk every month. Pretty much everyone is on strike. Your Chancellor has done something you're hoping the press don't find out about. The Daily Reckoning has turned. You have seconds to respond but every decision might please one faction and infuriate another.
Four groups hold your fate:
- Cabinet: Your inner circle. Lose them, lose control.
- Backbenchers: Your own MPs. Several have started a WhatsApp group.
- Media: They were briefly on your side. That was a different week.
- Public: Patient, mostly. They remember the big decisions.
Let any faction hit zero and it's over. A new Prime Minister inherits your mess and the world remembers every decision you made.

COMMONS COMBAT
Whenever your ministerial car feels like it, it will pull up outside No. 10.
Outside No. 10, your ministerial car will now start appearing whenever it feels like it, and whisk you off to The Commons, where the Leader of the Opposition awaits.
Hurl Insults, Tell a Dad Joke, or just Blame the EU! Do whatever it takes to battle out your record in Parliament and try and leave without embarrassing yourself or damaging your factions. Not in the mood? Send the Deputy PM, it's what they are there for, but the factions will notice.
Good luck ...
THE WORLD REMEMBERS
Each Prime Minister continues where the last one fell. Decisions echo forward. A bad call from the first PM can land on your successor's desk. The longer Britain has been ungoverned, the harder it is to govern.
Survive a term and face a general election. Win a majority and carry on into a second term, with harder crises, and a party that is starting to wonder if someone else might do it better. Lose and it's over. Britain moves on. It always does.
HOW LONG WILL YOU LAST?
Your record as PM will be remembered. The epitaphs are not kind. Your portrait will hang in a corridor no-one visits but you can do better than that. Maybe.
A work of satire. All characters, crises, and political parties are entirely fictional. Any resemblance to actual governance is purely coincidental.

What’s new
Release notes for the latest version, as written by the developer.
The Prime Minister's Office is pleased to announce the following ministerial updates...
NEW: COMMONS COMBAT
Parliament is getting busy again, it's time for the UK Autumn Budget and PMQs is back!
Outside No. 10, your ministerial car will now start appearing whenever it feels like it, and whisk you off to The Commons, where the Leader of the Opposition awaits.
Hurl Insults, Tell a Dad Joke, or just Blame the EU! Do whatever it takes to battle out your record in Parliament and try and leave without embarrassing yourself or damaging your factions.
Also:
- Not in the mood? Send the Deputy PM in your place.
- Prime Ministers can now resign, after at least 3 months (that's 1.5x longer than the life of a lettuce FYI).
- With El Niño around the corner, storms, snow and seasonal holiday decorations are forecast for Downing Street.
- iPhone Duo support: unfold and see the full scale of the crisis.
We wish to assure the public that any previous bugs were entirely the fault of the opposition, and their removal represents a decisive victory for the British people.

Is this US chart app missing in UK?
It showed up on a UK chart in the last 30 days, so it is not a gap.

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.
