Hi Community, I just started my way in product business and want to get suggestions from more experienced people about how the mobile app can be promoted with limited budget. I've created an IOS app for tracking net worth. Actually I was responsible for idea in general and did testing. Development, design and other things were outsourced from my personal savings. From the beginning to release was spent a half of a year, hundreds of hours and thousand dollars. It was much more than I expected so almost all budget that I planned was spent on the development. When the app was released I've tried to push it via social network. I bought Ads in FB and Instagram, but the ads gave nothing. The same thing with ProductHunt and similar services. Social ads didn't give any boost at all, posting on services/forums gives a few more downloads in the day when it was posted and that's all. Day after that new downloads again become near to 0. Also I spent some money to configure ASO for the app, but didn't see any boost as well. So daily my app is downloaded by 0-5 new users which is which is a very low rate. I know that big companies spend thousand dollars on promotion, but how to be if you are one person company? I would be very exiting to hear you experience about promoting mobile application. If you are interested link to my app and website bellow. Would be happy to hear any feedback about app's idea as well :) AppStore: https://apps.apple.com/us/app/balanceviewer-net-worth/id1476048552?ls=1 https://apps.apple.com/us/app/balanceviewer-net-worth/id1476...
