I mostly shared the launch post and ran promo campaigns on Reddit, ProductHunt, LinkedIn, Discord and even tried HN (got no replies here -‿-"). Since then, its mostly word of mouth.

Thanks to my customers' feedback, I've made a lot of improvements to the app as well. Feels good getting positive feedback and hearing from people about their use-cases. :)
