Best App or website for tracking the value of your collection. Vcp? Something else?

[BoxOfOldCards]

I collect mostly off back t206 cards. Mix of psa, sgc, raw. Also have a decent 50s/60s singles collection. I have my own spreadsheet i use to track what i have but it doesnt track value. I would like to find something else i can use that would be easy for my wife/kids to use if I ever get hit by a bus.
Really looking for something that can report a potential value difference between a common piedmont back and a drum back for example. If if can distinguish an SC 350/25 from a 350/30 even better.

Anybody have anything they use and like?

95% of this board will recommend VCP

They are right.

But I will offer up an alternative that you can explore for a week with a free trial (just cancel your membership if you do not like it before it charges you)

Card Ladder which is now owned by Collector's (i.e., PSA) is an emerging favorite of mine.

Card Ladder's quickness as well as its user interface and user experience is incredible.

You can get a full list of its features and pricing here (remember, you can start with a free trial)

I am a paid subscriber of both VCP and Card Ladder and do not see them as an exclusive pick one or the other choice. I use both while at card shows and while researching auctions.
