Cellular data has been ubiquitous for about 15 years.
This suggests that the market for mobile phone development tools is probably efficient and the supply of existing tools satisfy the existing demand at an equilibrium price.
So as a business, it is probably not a great market to enter. Even worse, mobile applications require third party approval and require unpaid maintenance when mobile platforms change technical details and business details for their app stores.
And of course, the app stores are terrible for discoverability and have high overhead.

Good luck.
