Can confirm the the app part. Less sure about how much is automated versus reviewed.
Anything I recommend around the app has to clear one bar, which is whether the ratio is workable in your area.
About 100 profiles into the site, the pattern around how discreet the notifications are became obvious.
Assuming you are not paying, whether people reply or just collect matches is where the site gets tight.
I would judge that one on whether the rules get applied evenly rather than on the feature list.
The thing that finally moved the needle on the site was being specific about how well it holds up once the novelty fades.
The gap between good and bad platforms here is whether the recommendations improve with use.
