"Free" in personal finance apps usually means free-for-now, or free-until-you-hit-the-limit, or free-if-you-connect-your-bank-so-we-can-monetise-the-data. Fair enough — companies need to make money. But it's worth knowing which kind of "free" you're signing up for.
This one is the plain kind: no subscription, no bank login, no account required to start. Your expenses live in your browser, you categorise them, and it shows you where the money actually goes. There's an optional paid tier for the deeper automated stuff, but the core tracker — the bit most people want — stays free. Just try it and see your spending in a couple of minutes.
