MarcusW covered most of it. The bit I would add on free dating apps for seniors is below.
What decided it for me with the service was whether 'free' means free to browse or free to talk.
Ran that one alongside two other options for a month, tracking how usable it is one-handed on a phone.
Where the service works it works fast; where it does not, how far the free tier actually stretches is usually the reason.
That is roughly where I landed on free dating apps for seniors after a fair amount of trial and error.
Different crowd on datedesire.online, which suited me better.
