Show HN: CrossPromote – Your own ad network Hi HN! While working on my side projects, I realized something - I have all these apps, but there is no easy way to cross-advertise them. Putting my own ads in my own apps is way easier and cheaper than paying Google or Facebook to do that. Moreover, there is a chance for higher returns if my ads are in the same niche as the app. At first, I made a basic implementation for myself, but I wanted something more - the number of views, clicks, platform-specific redirects (e.g. Google Play for Android and App Store for iOS), changing links dynamically, etc. That’s why I made CrossPromote Picture this: you have a travel tracker, so why not put an affiliate link to a service that offers global eSIM services? Or a multi-currency account? Travel insurance? Your other app that is a travel guide? The possibilities are endless, just like returns. CrossPromote is a simple tool for app and site owners to drop in custom ads, affiliate links, or cross-promos. Perfect for anyone who has an app or a website in some niche. The first version is done and ready to use. It’s a 100% solo project and I'm trying to find a product-market fit while gathering feedback that can help me grow it into a better service. Let me know what you think! https://bit.ly/43eYwIz October 10, 2025 at 05:10AM
