Hi all,
I'm an indie developer and I recently built an app to help people learn Chinese tones. I am a native Chinese speaker but I saw that a lot of my friends learning Chinese were having a ton of trouble distinguishing between the 4 tones, so I built an app to help them. Hopefully some of you will find this useful. It's free.
Check it out at https://www.chinesetones.app. It's free.
Thank you!
