Low compared to what? If he's making more than his operating costs, it's not low.
I'd love to make an extra $240 a month.

"I worked on this project during my free time (weekends, evenings, holidays) for approximately 12 months, from April 2018 to March 2019."
If by "free time" the author means 1h per working day and 4 per day on weekends, that would be ~680h -> 85 days (8h per day)(back to back). Not that's not a good ROI at least for me. I won't count the deeply unique value of "time not spent with family/friends/children".
I sincerely hope that this picks up and gets 4000 paying customers, but so far for a year's worth of work it's not impressive.
Also, young people's time has a different value from an older married with kids people's time.
(most young people I know spend tons of time on youtube, yik yak (zip zap? or whatever it's called), playbox x-one things, etc...)
Example: I could spend a week learning carpentry and build a dinner table, or I could buy it from IKEA for $40. That's a dumb move for most people, unless I am super interested in carpentry.
He spent time, not money. His statement is accurate.
Edit: It's a subjective point of view to say it's not "useful". I found it helpful to see what he did.
All time spent can't just be measured straight in money / hour can it.
In any case, if he's happy and proud of his project that's the worse I wish him
I have tons of side projects I've spent months on that never made a dollar
