Can developing a mobile application still bring income to a developer with an idea?

Question

Startups

I have an idea and the only sound way I can see to monetize it is to sell it as a mobile app. But I hear from everywhere that everything is bad and such a strategy has not worked for a long time, soon everything will be in the form of SPA / PWA clients of large services, where there is a more thoughtful monetization policy. Tell me, who is somehow connected with mobile development and / or tried to roll out their applications, how are things going?
ps Well, details like iOS-first or immediately cross-platform, I'm also interested.
pps Of course, I want to implement the idea, but still not guaranteed to go "in milk" with my efforts.

Answer 1

If you have a niche application, in some narrow specific segment, aimed at a solvent audience. That is quite possible. You are looking for a competent marketer, order a market research, then a prototype and a soft-lunch. Calculate how much you get from the user minus the cost of attracting. If you go to the plus, you scale, you launch fully. IMHO so.

Answer 2

Until you try, you won't know.
From experience, singles with a supir-puppy idea never shoot.

Answer 3

Make a plan.
A very detailed plan.
Describe the site, application, how you will promote it.
Give your texts to competent text builders
Launch MVP.
Try to find a competent seller.
After the first financial results, look for investors.
It is quite realistic if you are ready to work for 5-6 months only on your own resources.

Answer 4

There is only one answer - try it.
Don't try, you won't know.
And suddenly it really "takes off"?
