What I'm Using to Learn Chinese
Remembering Simplified Hanzi
I'm using this book by James Heisig to learn simplified Chinese characters. You can buy the book here (non-affiliate link). I actually would recommend buying books 1 and 2 on Apple Books as it's cheaper and more convenient.
Check out my plan to learn 3,000 Chinese characters in 120 days.
Anki
I'm using Anki as my spaced repetition software. It's free, open source, and you can customize it however you like.
I am currently working through this deck.
A Good Microphone
I use the Audio-Technica ATR2500 to record my audio. You can just as easily use your phone and record in a voice memo app.
