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.

Khamkui — Style your keys. Chat smarter.

DESIGN EVERY DETAIL

  • Add photos to the background and individual keys. Adjust their size and position.
  • Choose solid colors or gradients, with background blur and dimming.
  • Customize key shapes, corners, opacity, borders and depth.
  • Change key-label fonts, size, weight and color.
  • Style the whole keyboard, groups, rows or individual keys.
  • Adjust press colors and effects, preview your design and share a theme image.

Everyone can create, edit, preview and save custom themes for free. Premium is required to apply them to the keyboard. You can also choose a ready-made theme. The keyboard keeps your chosen theme; only the main app's interface follows your device's light or dark appearance.

QUICK REPLIES THAT ADAPT
Organize frequently used messages into folders and find them with search. Add variables such as “Hi {name}, your total is {price}.” Fill in text or numbers before sending, or pick a saved phrase from all folders or selected folders. Prepare a reply once and personalize it each time.

TRANSLATE OFFLINE
Download supported language packs online in the main app first, then translate on your device without an internet connection. Paste text copied from anywhere or type your own. Swap the source and translation, then copy or insert the result into your current text field.

MORE TOOLS ON YOUR KEYBOARD

  • Calculator: calculate and insert the result.
  • Numbers, date and time: enter numbers or insert a date and time.
  • Decorative text: choose styles for the text you send.
  • Symbols and Text Art: add hearts, stars, dividers and character art.
  • Delete All: clear text after confirmation.
  • Reorder tools and display icons, names or both.

START FREE

  • Thai and English typing, with Minimal and Night themes.
  • Create, edit and save custom themes.
  • Up to 3 quick replies in total, 1 folder and 1 reply with variables.
  • Up to 20 Thai–English translations per day.
  • Starter decorative text, symbols and Text Art, plus basic tools.

KHAMKUI PREMIUM
Unlock all included themes, apply custom themes, enjoy unlimited quick replies and folders, and access all included decorative text, symbols and Text Art. Translate all languages supported by Apple on your device, without the app's daily quota.

Monthly and yearly plans are available. Eligible Apple Accounts can try Premium free for 7 days, as shown before subscribing. The trial automatically renews into a paid subscription. Price and billing period are shown before purchase. Cancel in Apple subscription settings at least 24 hours before the trial or current period ends to avoid renewal. Deleting the app does not cancel a subscription.

GET STARTED
Go to iPhone Settings > General > Keyboard > Keyboards > Add New Keyboard and add Khamkui (คำคุย). Hold the globe key in a text field to choose it.

Translation requires iOS 18 or later, Allow Full Access and supported language packs downloaded in the main app. Once prepared, translation runs on your device. Ordinary typing and creative text tools do not require Full Access.

Decorative text uses Unicode. Appearance and support vary by destination app; Latin styles do not change Thai letter shapes. Theme fonts change your keyboard's key labels, not the font used by other apps.

Typed text is not sent to developer servers. Quick replies, themes and settings stay on your device. iOS may prevent third-party keyboards in password fields or certain apps.
