Nice to see journey like this here - big goal - but definitely achievable, wish you good luck! I'd like to ask you a couple of questions, hope you don't mind:
1. Do you outsource the process of developing apps you are going to promote but if you had nobody who could create apps for you, do you have enough coding skills to write an apps by yourself ? I'm asking this question because I'm curious, if you are also a developer who's just busy and can't find enough time to create new apps, or you are a guy who sees the potential of this market and want to conquer it, but personally you don't know programming languages to code an app?
2. When those people you hire to develop your apps will be ready to release it, then what happens next if this app is successful, do you just pay them for creating new app and it's end of the story for them or do they get % of earning for app ? I don't understand why those guys couldn't develop these apps and promote it in stores ? They must know the potential of this niche.
3. Once app is ready and you begin to promote it - who's the author of this ? Is there your name/your company name or is the coder of app somehow mentioned ?
Sorry if some questions are too private for you, but if someone starts a journey then for me it means that this person started it to track his progress and stay motivated but also to share some information/tips with the community
