What you get

Your collection, financially honest

Shelfworth gives your shelf the metrics it deserves.

💰
Cost-per-play dashboard
Every game on your shelf shows its real per-play cost. Watch the number drop as you log more plays — the most satisfying math in the hobby.
😬
Shelf of Shame report
The games you own, haven't played, and spent real money on — surfaced as a single list. Know exactly how much value is gathering dust.
🎲
What to play tonight
Filter by player count, time, and mood. Shelfworth nudges you toward games that need more plays — putting your money to work.
💸
Cull list
See the total value of the games you barely play — with one-tap export so you can list them for sale and recoup the cost.
📊
Play-value trend
Your average cost-per-play over time as a chart. Every session you log should push it down — and now you can see that it does.
☁️
iCloud backup
Your shelf and play history back up automatically to your iCloud. No account, no server — just your data, on your devices.

How it works

Up and running in 60 seconds

1
Import your BGG collection
Enter your BoardGameGeek username and your whole collection imports instantly — names, box art, player counts, and play times included.
2
Set what you paid
Enter the price you paid for each game. Shelfworth autofills MSRP as a starting point — adjust as needed, or confirm what looks right.
3
Log plays, watch the number drop
After each session, tap to log the play. Cost-per-play falls. Your Shelf of Shame shrinks. The collection starts earning its keep.
Shelfworth uses the BGG XML API to import your collection — game names, box art, player counts, and play times — so you never have to type a game title manually.
