Show HN: I built a small app for FSI German Course

Hi everyone. I am built a small application on top of FSI German basic course and I need some feedback regarding it.It is a small web app. Currently only Unit 01 is available. I will feed in the rest of the units later down the road as I use it myself.Some of the features includes- Slow and fast audio with every single word and sentence in this app. You can play them with a click of a button. No need to rewind a tap back and forth. - Flashcards with keyboard control to quickly go through the material and drill them out.You can access the website at https://detawk.com/ . There is a demo video on the landing page. Give it a look before signing up.If you have any questions or feedback for me, let me know. I hope you like the app.
