I made a dating/meetup app exclusively for Indians and for the NRI Indians (Non-resident Indians). https://www.nrimeet.app/ Available on IOS and Android. Gets me around $250 per month. I've not done much marketing either. Started as a hobby project after Covid and continued after. I also built an Indian Version of Neighborhood app (like Nextdoor). But I am not making any money from it. https://neighar.com PS: I am planning to scale up and also planning to spend some money on marketing. Investors are welcome!
