The six comparison guides
Each guide uses the same method: official US App Store listings and the developer’s own help pages, dated, with sources at the bottom. Duple publishes them and makes one of the apps compared, so none is an independent ranking.

What every guide compares
- Memory: whether the app remembers you across conversations, and how you reset it.
- Price: free tier, subscription and in-app purchase prices on the US App Store.
- Pictures and video: selfies, generated images and video.
- Voice: whether the app has voice calls or only text.
- Age rating: the App Store age rating, so you know who the app is aimed at.
We only compare apps with an iPhone App Store listing, so Android-only apps and browser-only sites are left out.
Where Duple fits
Duple is an iPhone companion app rated 16+ with long-term memory, a roster of companions, selfies and Live Selfies, and no live voice calls. It is not built for unfiltered or explicit roleplay and has no character catalogue. If you want those things, other apps in these guides fit better. Details: pricing, safety, FAQ.

Free to download on iPhone (iOS 26 or later), rated 16+. Check current plans on the listing.
