I built a free Steam achievement tracker that scores each achievement by how rare it is, I call it Nyx, but not sure on the name. Looking for honest feedback.

Hey all, I’ve been building a side project called Nyx and I’d like some outside opinions before I take it further. What it is Nyx is a dashboard for your gaming history. You sign in with Steam and it pulls in your library, playtime and achievements. After that it syncs about once an hour and turns everything into one score. How the score works Hours don’t earn points. Each achievement is worth more the fewer players have it: 64% of players have it: 13 pts 4% have it: 50 pts 1% have it: 100 pts The formula is 10 × √(100 / unlock %). Getting every achievement in a game adds 20% on top. Your total places you on a ladder of 7 tiers, from Iron up to Onyx, and each game gets a mastery grade from D to S. What else it does Library: every game with your completion and mastery, and how you compare to the average player History: a calendar of your play sessions and unlocks, plus a heatmap of when you play Objectives board: pick locked achievements you want to go after and move them through Backlog → Up next → Hunting → Done. Each sync ticks off the ones you’ve unlocked. Only you can see your board. Custom platforms: for anything Steam doesn’t cover, like an old handheld or a game you finished offline, you can add your own platform and enter games by hand. These count toward your hours and history but never toward the score, because the achievements are self-reported. Profiles: you can browse other players’ libraries, or a combined view of everyone on Nyx Light and dark themes, and a small mascot you can poke The added video is from my own Steam account + dummy account with test data.
