> I don't know why but the online dating experience has gotten worse this year. A lot more ghosting.
I'm not sure if you are defining what ghosting is properly. It usually means to have established consistent contact (at least a few days) or to have had a live relationship with a person, who then suddenly disappears.
Many dating apps are scams or scams to certain percentages or an extent. Thus they have the app send automated responses or people (often male) working for the company are sending replies to customers to keep them interested and take their money. These automated or company responses were never real women looking to date, just scamming.
It should also be noted that this should include "boost" or increase response gimmicks to take more money from desperate customers (usually male). So basically whatever their male customers were paying meant nothing, so to actually get real/more responses, they must pay more. Which can be paying for a company employee, to send responses to male customers to keep them engaged with the app or site.
> I recently removed 3/4 of my matches because they were not answering after 2 weeks.
On average, people will usually have set up a date to meet before or by 2 weeks. Non-response can mean the person has moved on or met other people, the 2 week mark is not unusual for that to occur. If anything, you should be removing non-responsive contacts after a set period.
> A lot more ghosting...
Actual ghosting has always been a thing with dating apps and sites, to include "one night stands". Because of the huge ratio of men to women on apps/sites, many women can be observed quietly "abusing" apps/sites to run through large number of male customers for "stealth" sexual encounters or for "fun and games" until they think they have hit "Lotto" with a particular guy. The other "throw away males", are the ones who the women ghost on, but because they are male it is considered acceptable or at least not openly discussed.
Where ghosting can become an issue, is when certain men (particularly high demand/high status/good looking males) do it to women. This can lead to various women openly complaining about it. Never mind all the men they may have rejected or ghosted on, but rather its a "crime" for it to have happened to them, and for a lucky/high status/good looking guy appearing to be having too much fun running through many women on an app or site (like the women running through guys). Such women can be so vindictive, to the extent that they will attempt or even accomplish doxing such men, or continually whine about it in public. Despite this happening much more frequently to male users, dealing with women. Many women don't even blink, when it comes to ghosting guys and jumping to the next offer, for whatever excuse.
> ...introduce a calendar feature where the dating app can automatically pick a time and safe place for a meet (a public place, usually) depending on your availability.
You can not force or trap women into dating a guy from an app or site, nor can you use software to remove the fear of rejection. The guy will usually have to face rejection, by asking the women out on a date. She will either accept the offer or not.
What you might can do, is establish rules or a culture where if a person flakes on meeting or is abusing the site to catfish and prank others, then they can more easily get banned from the app or site. When a dating offer is accepted, it is noted by the app/site, and both parties are expected to meet. If a person can't meet, then they can reschedule and are expected to make the rescheduled date, else face a possible ban from the app/site.
However, this is quite hard core, and gives a lot of authority to the app creators or site to get involved. This then can be abused by people that feel they are "owed something", and then constantly whining about it. Like if a woman meets a really rich and handsome guy who she thinks is perfect for her, except he does not feel that way about her. After their first date or sexual encounter, he decides to move on, but she decides to continually complain to the app creators or site as if they can force high status men to love her.
It might be better for people to not rely so heavily on apps/dating sites, particularly to the extent of wanting or trying to force rules on others. Sometimes, just going outside and facing your fear of rejection, and actually speaking to or meeting people can be a helpful option.
