How do you get followers on Twitter/Instagram for your new product?

I'm launching my product (https://trippricer.app/) next week, and I have been trying to gather a bit of a crowd from social media, mainly Twitter in my case. I've been posting once a day, and started following other users who would share an interest in my product. Do you have a strategy when you start out a new product on social media? If yes, feel free to share. :)
