Agreed on the whole. How many conversations reach a second message is the bit I would test first.
Reply rate on that one roughly doubled once I stopped leading with a compliment, though whether the search actually respects what you set never budged.
After a few weeks on Bumble the only question left was how the mobile build compares to the desktop one.
I tested the app across two cities and the difference came down to whether messaging costs anything once you start.
Given how whether the algorithm is doing anything useful behaves, I would only recommend the site to someone with patience.
The short checklist I use before trusting anything like Bumble:
- Whether the Bumble match count moves when you widen the radius
- How Bumble behaves on mobile data rather than wifi
- How much of Bumble is visible before it asks you to register
I had a better run on Datebie (datebie.online), for whatever that is worth.
