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.

Learn Korean, Japanese and Spanish by speaking from the start!
Practice speaking essential expressions in first-person POV scenarios.
===========
- "But I can just learn Spanish, Korean and Japanese by watching Netflix!?”
Just like if you were learning how to swim, you’d go into a pool instead of watching videos of Michael Phelps swimming. You can't learn Korean by listening to NewJeans or speak Spanish by singing Despacito. Don't get us wrong. We love music. But if your goal is to ACTUALLY SPEAK, you have to, well – SPEAK! TEUIDA's first-person POV conversations will get you speaking everyday expressions in real-life scenarios.
- 3 min > 30 min
We believe that 3 minutes of actual speaking will help you more than 30 minutes watching someone else speak (long lecture videos).
Why waste your precious time learning about a language when you can learn by speaking it yourself? Our interactive lessons not only get you to speak with the tutors but gives instant feedback on your pronunciation.
- Overcome fear of speaking
Research shows that one of the greatest barriers to speaking a language is confidence. After all, what's the point of knowing all the grammar rules and verb conjugations if you can't speak when the moment comes? TEUIDA helps you overcome fear of speaking by simulating real-life scenarios but without all the social anxiety. (i.e. Our characters won't throw shade at you for mispronouncing!)
===========
Here’s a list of things that make TEUIDA different:
- Essential expressions:
No more weird, awkward phrases (translated by bots) that no one actually use in real life. (Let's be honest, when was the last time you had to say "I am a boy, you are a woman" in real-life?)
- Effective curriculum:
Once you master our curriculum, you will be able to know the basic vocabularies, grammars and of course, speak to your friends in Korean, Japanese, and Spanish!
- Taught by Bilingual Tutors:
Our crazy selection of fully bilingual tutors not only speak Korean and Japanese but understand where you’re coming from. They know exactly what to teach you because they've been in your shoes!
- AI Pronunciation Analysis:
What's the point of repeating sentences aloud if you can't tell whether you're pronouncing it right? TEUIDA has a convenient voice recognition system that will give instant feedback on your pronunciation.
- Fun, Interactive Stories:
We believe that learning and fun are not mutually exclusive. In fact, learning is most effective when it's fun! You'll find yourself laughing, screaming and at times even cringing with the characters.
- Real-life Scenarios:
Real-life everyday situations! Everything from ordering a drink at the cafe to asking for directions!
- Culture-specific tips:
A wise man once said that "the person who learns language without learning culture risks becoming a fluent fool". We believe understanding culture is the key to learning language. So we hand-selected each scenario to reflect the culture-specific elements of that specific culture!
So... what are you waiting for? Stop reading and start speaking with TEUIDA!
