Hoping someone here has actually tested dating apps for nerds rather than just read about it. Same story on anime: most of the disappointment traces back to how far the free tier gets you. Anime is the clearest case of it — it is worth checking how far the free tier gets you before you look at star ratings from strangers.
I judge anime nerds on one thing: the platform surfaces profiles far outside your radius, so it pays to keep the first meet public and short. The anime nerds angle is worse, because the deciding factor is the signal-to-noise in search, having tried a handful of these. Anime apps is where I would start, since the signal-to-noise in search counts for more than how slick the interface looks, having tried a handful of these.
If anime nerds is your priority, the honest advice is to read the newest reviews rather than the top-rated ones, on the evidence I have. My honest read on dating apps for nerds: the platform pushes notifications that lead nowhere, which makes any straight comparison unreliable. What has actually worked for you on anime apps, and what would you avoid?
