I have a spreadsheet that has grown from a basic checking account ledger to include a full list of all of my card, signup bonuses, reward tracking, interest tracking, and all kinds of other stuff. I now keep it in Google sheets for easy access.
I tried Mint and didn't find much use for it. I just looked at Wallaby and don't see much use there. It does not seem to get the right card, for example telling me to use my Blue Cash Preferred for 3% at gas stations instead of my PenFed for 5%. It also does not seem to let you assign values to points or consider a branded hotel card might be better than the 3X of a Citi Prestige.
Part of my spreadsheet has a listing of cards and the point values I assign based on my historical redemption. I then use conditional formatting to color the matrix for at a glance review. If my value of a point changes it is a simple matter to update one cell and it will recalculate.
