I am studying Chinese and I find this app very useful. One suggestion I have though is that in Chinese when giving someone your phone number people usually say yao 幺(yao) instead of 一 (yi) because 一 (yi) can be mistaken for 七(qi),but other than that the app has been perfect for me. Thank you.

Paid $4.99 instead of the advertise $9.99 for the lifetime Pro version. They must’ve correctly lowered it because this isn’t worth $10 as it is. Games are fun and useful. $4.99 is barely with it.What I want to see:1. Leaderboard with other players to gamify the experience.2. My scoring doesn’t work so I don’t see my tally on the main page. Update - sometimes it shows, sometimes it doesn’t. Inconsistent. 3. Metrics over a longer period of time than just a week. 4. A more natural and less computerized voice.5. Personal bests for each game.6. A sped up version that does not distort the voice much and does not (according to other reviewers) erase your scores by choosing that speed). There is on other app in the App Store that has no rating made by a doctor with in-app purchases. Maybe that is better. I didn’t buy it because some guy on Reddit who went from 0 to C1 fluency in French in a year said he used this app from B2 to C1 fluency. All in all, I recommend it.Update - I restarted my phone and now the app shows my score. Not sure why I needed to do that. Maybe it has something to do with buying the pro version.I do enjoy the time spent and streak tabs on the home page. What brings it home for me is that it shows total hours/minutes (I wonder if it’ll do days) spent on the app AND is drills down to minutes spent per day. It seems you can go back to any day every spent. I love metrics so that is useful to know.

THE GOOD: If you’re looking for an app to practice auditory recognition of foreign numbers, this is a good choice. It’s easy to use and has a decent amount of languages to pick from. You can adjust the number range, time length of games, and speed. THE BAD: the voice is not very authentic. It’s a computer voice reading numbers so pronunciation isn’t all that great. If you increase the speed it just sounds like its on fast forward and it’s not very authentic. Because of this, the speed settings are pretty much useless. Next, just recently the game deleted all of my tracking info.

This is great. You want to hear and immediately recognize numbers in a foreign language and this is it! Check the block of understanding every number you hear.
