Guess you have no idea with what apps you can make money :) If you have a decent app and good pricing you can convert something between 1-5% of downloads to paying customers. With his audience and reach he can easily make real money. Probably not life changing, but still a few hundred bucks each month.

He said on a podcast that he spent "6 months" developing it. I very much doubt that was 6 months of full-time work, but even if that was only 10 hours a week, and even if the "cost" was let's say $100 (probably much more) an hour, that's around $25k or 7 straight years of $300 a month (that never goes down for 7 years, aka impossible) to recoup his investment. That's an absolute low end, I think you could easily argue the cost was 4x that, which means it would take 28 years of sales that never dip to break even. There's no possible way he could make anything besides less-than-nothing level money at $300 a month or anything close to that amount.

As he explained on his podcast, this project was designed to solve his own problem. The problem with apps designed to solve your own problem is that very often, your problem is not 1) shared by others willing to pay or 2) you don't solve the problem in the same way others want to solve a problem.

Just for reference, $25K spent in time and then being able to talk intelligently about modern iOS development on a podcast that generates $16K an episode seems like a good investment.

And “time isn’t money”. It wasn’t like the time he spent developing it would have been spent working on something else.

A few hundred bucks a month is for all intents and purposes "nothing". It's a rounding error in terms of the time he spent on it.
