Obstacles

This is not the first time you have thought about it

Something stopped it last time, and unless that something has changed, it will stop it again.

How many subscriptions are you paying for right now?

Four reasons, four different starting points

No time

Then the first step has to be small. One screenshot of one screen produces a partial list, and a partial list is already more than nothing.

Did not know where to look

Then the problem is a map, not willpower. Card, App Store, Google Play, PayPal, e-mail receipts — five places, and that is the whole list.

Tried it and it did not stick

Usually a spreadsheet, abandoned because it needed manual upkeep. Anything that depends on monthly discipline fails for the same reason.

Did not want to hand over bank access

A reasonable objection, and the reason this particular tool reads a screenshot instead.
