Budgeting apps tell you what you already spent. Banks send summaries after the damage is done. None of them are there in the moment — when you're hovering over "Add to Cart" at 11pm.
Mull is a windshield. It steps in before you spend, connects the purchase to something you actually want, and gives you a real choice — not guilt, not a lecture. Just a moment to think.
"Most finance apps are rearview mirrors. Mull is a windshield."— Mull product philosophy
Most tools find you a coupon after you've already decided to buy, or just track the damage afterward. Mull works before you spend.
Pick a goal, then tell Mull a bit more about it. That's it — Mull connects every purchase to it from then on.

Some links in Mull earn us a commission. This includes the popup's "Buy anyway" and "See a smarter option" buttons, as well as links on the settings page — like investing platforms shown for the Build Wealth & Invest goal, and partner links shown when you complete a Travel, Home, or other goal. If you complete a purchase or sign up through one of these links, the retailer or platform pays Mull a small commission — at no extra cost to you. The price you see is the same price you'd pay going directly to the site. On the settings page, each platform is clearly tagged with its current commission status, so you never have to guess.
Not every link earns us anything. Some sites Mull links to — including Amazon — do not pay Mull any commission at all, due to their own program restrictions on browser extensions. We still show you these options because they're useful — not because they pay us. We'd rather tell you the truth than pretend otherwise.
We never let commissions influence what we recommend. The "smarter option" shown for each category is chosen because it's genuinely a good, trusted place to compare — not based on which one pays Mull the most. If a category has no monetized option at all, we still show you the best one, clearly labeled either way.
Your data is never part of the deal. Mull doesn't collect or sell your information to anyone, ever. Affiliate commissions come only from completed purchases you choose to make — never from your data. See our privacy policy for the full details on what Mull does and doesn't collect.
