Hi there,
The cost of a mobile app depends on many factors, including your expectations for an app. If you are okay with something simple and not multifunctional, you can develop an MVP, it's the cheapest way, and you can do it by yourself using a no-code platform.
But if you need something more global, which can bring more revenue, you should hire developers, and the cost will vary widely then.
If you are curious, you can check some posts from developers about mobile app development costs - https://spdload.com/blog/app-development-cost/.
Hoping you found answers to your questions.
