How does one forget about a subscription? Doesn't everyone periodically review charges to their credit cards and bank withdrawals to make sure they make sense, and to pay bills that are due? If not, how do you know day-to-day how much money is available in your account or discover fraud? I'd be bouncing checks left and right if I didn't keep a close eye on my balances.
I'm not living paycheck to paycheck, so I'm not in the habit of looking at every transaction. The monthly/quarterly budget and subscription reviews that truebill prompts are massively helpful.
It is a bit aggressive in classifying recurring charges as subscriptions, but that's better than the alternative.
