Fair questions
Is this financial advice?+
No. These are observations from tested patterns, not financial advice. Cards are collectibles first. Whether anything belongs in your collection is your call.
How do I know it works?+
Don't take our word for it. Every call ever made sits in the public ledger with its outcome. Check the record, then decide.
What happens when you're wrong?+
It stays on the record forever. Go look. A record with the losses removed isn't a record.
Where do the prices come from?+
TCGplayer for the US market, Cardmarket for Europe, and Japanese market prices, refreshed daily, with real eBay sold listings alongside and PSA, CGC and BGS population counts on the card page. No estimates, no vibes.
Do I have to pay to track my collection?+
No. The binder is free and unlimited. Your cards are valued daily and the playbook runs on everything you hold. You only ever pay if you want today's calls the moment they fire.
How is this different from other collection apps?+
Other apps tell you what your collection is worth. We tell you what the data says to do about it, and we publish the record of every call so you can check whether that's worth anything. Nobody else in the hobby shows you their misses.
Does Buy Watch mean I should buy?+
Buy Watch means our system expects the card is more likely to rise than not. A tested buy pattern is firing: the kind of setup where, on our live record, 2 in 3 cards finished higher within 8 weeks, averaging +24.8%. Sell Watch is the mirror: the patterns that historically kept falling. It's the odds, read from the data, not a promise. Whether the card belongs in your collection is your call.
Is there a mobile app?+
Yes. The Android app is live on Google Play and the iOS app is on the way. Same live board, same binder, in your pocket.
Can I cancel anytime?+
Anytime, from your own account page, no emails and no hoops. Your binder and the free tier stay exactly as they were. The mid-year sale rate covers your first 12 months; after that plans renew at the standard rate, and we'll never move you to a new price without telling you first.
Observations from the data, not financial advice. The Ledger is public so you can judge every call before spending a dollar. Prices in USD; your card is charged in your local currency at checkout.
