Week 1 of my app marketing journey

The first few days was the toughest.. Not knowing where the fish am I going to market my app, and also not know how to do so (without getting banned!)

So far, what I have done is exploring what marketing channels that I can play with.. I tried:

1. Building a brand on tiktok, where I draw fictional characters teaching topics relating to the niche of the app, then advertising from time to time

2. Posting on reddit, where I show the features of the app

3. Helping/Replying to redditors, where I try to solve problems that redditors in my niche community app have. Or, when people showed any interest to my app, I will DM them if they face any problem that I can solve...

4. Post on threads (literally no result from this lol)

In total, I received 4 people into the waitlist of the app! In the future, I might add a meme-able feature into the app and post it on social media or smth..

Is there anyway I can improve..? Love you guy's thoughts on these and where I can improve...
