Indie App Ads is a mobile advertising network designed specifically for independent app developers. Its primary function is to enable developers to both host advertisements within their own apps and purchase ad placements for their apps, creating a peer supported ecosystem. The service is operated by tsdev and is available at app-ad.network. It is a separate service from Indie App Hub, functioning exclusively as an ad network for ad display and ad purchasing. The platform offers several key features. Developers can monetize their apps by displaying ad units or using an App Introduction API that returns "spotlight" and "apps" data for flexible UI integration. The network provides a Trust Score system that monitors for invalid clicks and manages reward holds to maintain ecosystem integrity. Advertisers can charge their ad balance with a minimum of 500 yen and begin CPC (cost per click) campaigns, with standard ads starting at 1 yen per click and app introduction ads at 5 yen per click. Revenue from click rewards and 60% of sponsor frame sales are distributed to publishers. A "Today's Recommendation" slot on the app introduction screen is available for daily purchase. Typical use cases involve a developer signing up for a free account, registering their app, and then choosing to either place ad inventory on their app or create an ad campaign to promote their own app to other developers within the network. The workflow includes setting up ad units or the API, charging the ad balance, and managing campaigns through the service dashboard. Currently, the service is running a Beta Program, listing participant applications sequentially.
