I stuck with most of the free apps over two or three attempts, and the honest result was that the read receipt setting mattered a little most. Although apps with a strict photo policy look similar, the moderation queue differs noticeably, though it depends heavily on where you live.
Judging by my own inbox, if you are new to this the answer is usually to widen the distance radius early on rather than keep the first message short and specific.
- Keep the first message short and specific, because the first week is never representative, and that alone put me off
- Avoid opening with a compliment, because the difference in reply rate is obvious, which most people notice within a week
- In my experience, I'd give it a full week before judging rather than widen the distance radius early on, since most complaints trace back to that one thing
- I stuck with the regional platforms since the start of the year, and the honest result was that the boost system mattered marginally most
The thing that finally clicked was that sites that skip verification have started throttling messages over the last month. Granted the ones with a paywall look similar, the free tier differs somewhat, so results vary more than you'd think.
If you want something casual, read the last few pages of a thread before asking — it saves a lot of wasted evenings.
If distance is the sticking point, the Flurrydate forums is more forgiving about the local side of things if that matches what you want.
