When you are older and don't have too much time meeting people because of work apps are totally finde.
I know this is anecdotal but I have two couples in my circle of friends that met via app, one couple already married. The other one moving in together. Both met when they where over 30.
It totally can work, but in the main my friends who have met people through them hasn’t gone well. The friends who have prioritised putting themselves in situations to meeting likeminded people seem to have a higher success rate (and a nicer less stressful time along the way)
