| You want an app that actively pulls you back in | Progression mechanics with unlocks you genuinely value, plus proactive messaging controls you can set | Engagement design can convert into daily obligation and attention cost |
| You want a companion that remembers a running relationship | Documented retention behaviour and a test where an early detail returns unprompted | Deeper memory tends to sit on higher tiers and is hard to verify before paying |
| You want visible personality variation between sessions | Moods that alter response structure, not just adjectives | Surface-level mood layers can feel repetitive within days |
| You want to design your own companion | Creation controls that produce demonstrably distinct behaviour across personas | Setup takes real time before the product becomes enjoyable |
| You want companionship without messages arriving unbidden | Explicit frequency settings for any proactive messaging | Fewer notifications may mean less of the continuity you were paying for |
| You want to judge the product before spending | A free tier that covers the matched dimensions rather than only the gallery | Free tiers are usually shaped to withhold exactly the features a serious evaluation needs |
