Everyone starts with a spreadsheet. Here is where they stop working, and what to do about it.
Where a spreadsheet breaks
- Values go stale immediately. A spreadsheet records what a card was worth the day you typed it.
- Set completion is manual, and recalculating "what am I missing" across a dozen sets by hand is miserable.
- Variants get muddled. Recording "Charizard, holo" is not enough to price it — printing, condition and language all change the number.
- It does not tell you anything. A list of cards is not the same as knowing what moved, what is close to complete, or what to sell.
What to look for instead
- 1.Prices that update themselves, with the source and refresh rate stated openly.
- 2.Condition and printing recorded per copy, so two copies of one card can be valued differently.
- 3.Fast entry — searching a catalogue or scanning with a camera beats typing.
- 4.Set completion worked out for you.
- 5.Export. Your data should be yours to take.
What this site does
Log what you own and you get a running total, a 30-day change, an all-time high, a singles/sealed split, completion rings per set, and the movers among the cards you actually hold. Add cards by catalogue search, by camera scan, or by bulk import if you already keep a list elsewhere.
It is free, with no card required, and the collector guide documents each part. Browsing set lists and prices needs no account at all.
