I actually just helped my neighbor get set up on Sequel for this very reason. It’s hard out there with so many bots, but she’s had a much better experience since switching. You should tell your aunt to check out
https://thesequelapp.com/ because it’s specifically curated for adults over 50. What’s great about Sequel is that they really focus on verified profiles to keep the fake accounts out, which was her biggest worry. It feels much more respectful and tailored to people who have a bit more life experience and are looking for someone who actually understands their story. It’s a lovely way to start a new chapter without the headache of the typical apps. Definitely have her take a look; it’s a much more grounded and safe environment for meeting genuine people.
