Hey looks good. But latest patch happened days ago and it’s not updated? Or at least it doesn’t reflect it does. Some monster features are not explained well. Good effort.
Developer Response
Hey Riggs78, quick update: both fixes are now live.The patch detector bug is fixed, so v0.103.2 (and future patches) auto-import properly. The monster explanations also got a pass: the behavior prose is much more detailed now, especially on boss fights where it was thinnest.If you have a few minutes to give it another shot, I'd love to hear if it feels better. And if it does, an updated rating would genuinely help us a lot.We're a tiny team and reviews like yours are how we know what to prioritize.Either way, thanks again for the specific feedback. It's the kind that actually moves the app forward.
AI Slop
Ice-Town
This app is a blatant low-effort cash grab. It promises “no hallucinations,” but it’s hallucinating in the app description! What is “blood magic”? Don’t download SpireSage under any circumstances. Watch a YouTube tutorial or something.
Developer Response
Hi Ice-Town, thanks for the honest feedback, and you're right to flag "Blood Magic."That phrase was a leftover from a pre-launch planning draft that slipped into the store description and it's not a real STS2 mechanic. The app's AI companion doesn't actually reference it and it pulls data from verified archetypes.I'm shipping an update this week. If you'd give it another look after the update, I'd appreciate it, and if something is wrong, please send a screenshot to support@spiresage.app so I can investigate it.
- Fixed a bug where users can't login nor signup the first time the app is opened.
- Minor UI improvements
