WHAT'S NEW
Your gems, one at a time
The recommendations screen has been completely redesigned. Gems now come one at a time, and you decide on each: "Not for me", "Save for later", or "Already seen". Got it wrong? An Undo button catches the slip. After a dismissal you can say what didn't work : not my genre, too long, not the right moment. Cards also show the streaming platforms and, for games, the platforms you can play on.
Every gem explains itself
No more suggestions out of nowhere. Each work tells you where it came from: "Similar to… , which you liked", what it shares with your tastes, and how closely it matches : from "Close to your tastes" to "Right up your alley!". In an Echo, the strength of the link is shown, from very strong to distant. The trailer is one tap away.
A sharper engine
Under the hood, the recommendation engine has been reworked for better Expeditions and Echoes: more variety from one session to the next within a saga, better tie-breaking between works with similar scores, room made for safe bets, and Expeditions that adapt to how mature your profile is. Echoes now keep the best-liked works instead of being capped by a similarity threshold.
Dismissed a gem by mistake?
A dismissed work is no longer recommended to you. A new page gathers them all, with the date, and a "Change my mind" button puts one back in circulation: it can appear among your gems again.
Echo: the sequel awaits
Start an Echo from a work that has a direct sequel and the sequel takes the spotlight: the next volume, your place in the saga, what comes before and after. And across all your recommendations, a saga now points you at its entry point rather than a volume picked at random.
Your profile is taking shape
If you're just starting out, Gemster says so plainly: your first gems lean on widely loved titles. On your dashboard, a gauge tracks your progress towards an expert profile, and every rating you add moves it along.
Invite your friends, wherever they are
You can now invite someone by email or through a shareable link, with a name and a short note if you like. They land on a welcome in your name, with a glimpse of your latest gems. As soon as they sign up you're friends, and you get a notification. A new Invitations tab tracks what's pending, and you can cancel a request sent by mistake. Friend search has been rebuilt: it separates people already on Gemster from those still to invite.
"Follow" becomes "Save for later"
The wording now matches what people actually do. A work you save joins your "Saved works", where you find its upcoming releases and updates from your dashboard.
FIXES
• Series: opening a work takes you to the season matching your progress
• A clearer title when you're all caught up, and a more compact progress panel
• Ordered series: your progress shows on the work page, and the catalogue now covers manga and comics too
• Books, comics and manga: the original publication date and your edition's date are told apart, and you can date a reading from the original publication instead of being held to your edition's date
• Steam: playtime and activity from older imports have been repaired
• Dashboard: the getting-started and platform cards are grouped together
• Search: edition and video titles are found more reliably
• Sharing: the attribution is centred and the author's profile is now clickable
• Recommendation cards, trailers and navigation: many adjustments on mobile
