The measure I would actually check on dating apps for big women is whether you can hide your location convincingly.
About 60 profiles into it, the pattern around whether the recommendations improve with use became obvious.
If you bounced off this before, revisit the service and check how much of your profile is public by default first this time.
The reason I stopped recommending some of these is what the free ceiling looks like in practice.
For a second opinion I also cross-checked the Luvdate community threads.
