I developed many popular apps which generated over 7 million downloads in the app store as an Indie developer. I never spent a dime on Marketing. The key to a successful app is your presentation in the App Stores orASO (App Store Optimization). As it's a tedious task to create App Store Screenshots in device frames for all kind of screen sizes and languages I created StoreShots for myself.
As I shared the tool with fellow developers, the feedback was very positive and so I decided to take the project public. It is developed with me as a developer in mind and with a fair pricing, which is based on usage and not forgotten monthly subscriptions.
I hope I can save you some work with my tool and am keen to know what you are missing or how I can improve.
