### 3/5 — Needs Improvement

*2026-01-29*

This app is great if you already know the numbers and just need to quiz yourself. If you want to learn the numbers there is no way on this app to input or select a number and hear what it is in japanese.

### 4/5 — Almost perfect

*2025-09-29*

Dear developer, Please add a study screen where I can learn from a list/grid of numbers and counters. Also when time runs out please reveal the last uncompleted number automatically. 

Additional game modes would be nice as well. Like an infinite/endurance mode where you answer until you are wrong.

### 4/5 — Great learning app with some flaws

*2024-12-16*

The customization is great, the audio is top notch, very helpful for a beginner Japanese learner. I especially like being able to replay the audio. I would love to pay for the app if it included a screen showing all the users answers at the end, clearly showing the players answer on one side with the correct answer on the other side. Maybe color coded, green=correct or red=incorrect. Also I feel like I’ve gotten the same number 3 or 4 times in quick succession, if there is a way to limit repeats somewhat. Overall love the app though.

### 5/5 — New to Japanese

*2024-04-24*

I have struggled with numbers for a long time and I started using your app and I finally understand how to count past 😂

I think, forcing myself to hear it through your app is helping.

I will probably use this every day for about 5-10 minutes
