This is actually great feedback (even though on the surface it looks like a "your idea won't work" message).

But to see a list of the top challenges from a close competitor is what I think most developers should look for. That way, they can either fix those problems or look for ways around them.

Also not to be a downer, but there are tons of time tracking apps in the market.

It's saturated, and honestly not a big pain point to solve for most people.

Customer profile that make sense and might retain: freelancer, agency that employ freelancer.

General public will find time tracking cool, but they majority won't use it day to day because it doesn't solve a problem.

Or it solve a problem, but resolved in a short period of time.

You can use app.sensortower.com (pretty accurate with some margin of error) to benchmark revenue for similar apps—at least those that released on App Store.

It may work, but some luck is required along with the right market fit. For example, a few years ago I shared similar concerns to the author of Session time tracker[1] when he was starting the app's promotion. Back then I believed he won't make it either, but, as far as I know from his twitter, he managed to reach at least a decent 4-digit revenue. Although his product is subscription-based, so there's no endless acquisition trap like in case of Taim in Qbserve.
