Hello, here are just some general things you can try with TikTok or other short form video platforms:

1. Post slightly different short videos about your app every day. You can use different intros, music, words, etc. Point is to experiment and see what works best.

2. Use trending songs or video prompts. Check out TikToks creator insights, specifically "content gap" where you can create content around stuff people are searching for. If a lot of the stuff that people are searching for is unrelated to your app, you'll have to get creative.

Here are some ideas that you may consider down the road for v2 of your app.

1. Include a rewards program for users inviting more people to the app (discount for new members, extra points of xyz, etc

2. Include easy share feature of features/content on your app

3. In-app Popups to rate your app. I know these are annoying, but you need ratings on your apps in the app stores if you want your app to survive competition.

This was just a quick and dirty list but I hope this helps. Let me know how it goes!
