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.

C. Maxwell Churchward's Tongan-English Dictionary, for iPhone and iPad.
The most complete digital record of the Tongan language: 37,428 entries and more than 43,000 definitions, hand-transcribed from Churchward's 1959 dictionary and searchable in both directions.
Whether you grew up hearing Tongan at home and want to understand more of it, or you're learning the language for the first time, it's here whenever you need it.
SEARCH THE WAY YOU SPEAK
Macrons and glottal stops are awkward to type on a phone, so you never have to. Type "faele" and the app finds "fa'ele". Search Tongan to find the English, or English to find the Tongan — same box, both directions. And when the word itself escapes you, describe it: the app searches inside every definition, not just the headwords.
FOLLOW THE LANGUAGE
More than 63,000 cross-references are tappable. Jump from one entry to a related term and back again without ever losing your place.
ROOM TO READ
On iPhone you get one word at a time, full width. On iPad the word list sits beside the definition, so following a cross-reference never costs you your spot in the list. Light, dark and system themes, plus a choice of app icons.
WORKS COMPLETELY OFFLINE
The entire dictionary lives on your device. No account, no connection required — on a plane, in the islands, or anywhere the signal runs out.
A LIVING TRANSCRIPTION
Every entry was transcribed by hand from the printed dictionary, and that work is ongoing. Corrections and refinements ship regularly, and you can report a mistake from the bottom of any entry.

What’s new
Release notes for the latest version, as written by the developer.
A new Proverbs section brings together 111 palōvepi from across the dictionary — each with its English gloss and a tap-through to the entry it comes from, searchable in both languages. Plus data corrections and fixes.

Store check Oct 15, 2026
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.
