We're launching next week, do you have any tips for me?

Next week, we will be launching "Retime.so". A successful initial launch is crucial to attract good traffic on Retime and receive valuable feedback from users. I have heard that Product Hunt (PH) may not be as effective as it used to be. Can you provide me with any suggestions on how to improve our launch? How can we increase the number of upvotes and comments? PS: https://www.producthunt.com/prod...
