Promoting a mobile app

I launched a mobile app for financial planning, but installations are very slow. Targeting on social media is expensive, and the results are unstable. Are there any alternative advertising formats that are suitable for mobile products and don't eat up the entire budget?

I had a similar situation with my own app, and push notifications worked well. This format allows you to reach users directly through their browser or mobile device, and the cost is often lower than on social media. I recommend reading a detailed analysis here: https://richads.com/blog/push-notification-advertising/ — it explains how push campaigns work, how to segment your audience, and how to optimize CTR. Thanks to this format, I was able to scale installs without a sharp increase in budget and get a steady stream of new users.
