Every impulse buy starts the same way. You see it, you want it, you tap. CutCut puts time between the wanting and the tapping. Instead of buying it, you save the wish. CutCut sets a cooling-off period based on the price: a couple of hours for something small, days or weeks for something big. When the timer runs out, you decide with a clear head. Most of the time the wanting is already gone, and the money stays yours. HOW IT WORKS 1. Save the wish. Share a link from Safari, paste a URL, or type it in. CutCut fills in the name, price and photo. 2. Wait. Every wish gets a timer that scales with its price. Choose Classic, Strict or Extreme. 3. Decide. Buy it without guilt, or let it go and watch the money you didn't spend add up. FREE ⢠Wishlist with automatic cooling-off timers ⢠Import from Safari, Amazon and most webshops ⢠A reason for every wish and a note to your future self ⢠Calculators for work hours, cost per use, investment and impact ⢠A reminder the moment a wish is ready to decide ⢠Your real numbers: saved and spent ⢠Share cards for your progress CLARITY ⢠Unlimited active wishes (the free version keeps two at a time) ⢠The Outlet: a shop where nothing is real. Put your own wishes in the cart, walk through the entire checkout, track the delivery, and when the pretend parcel arrives, the money you never spent is booked as savings. ⢠Circuit Breaker: a one-minute intervention for the impulse that hasn't even made it onto the list yet. ⢠Clarity Score: a score from 0 to 100 across five dimensions, with a short check-in every month. Your real decisions count towards it, not just your answers. ⢠Monthly Focus: one area to work on, plus two or three small actions you tick off straight from the widget. ⢠Ten guides on how spending really works ⢠Home Screen and Lock Screen widgets ⢠Detailed charts and the full history ⢠Six extra notification styles, from gentle to drill sergeant ⢠12 extra app icons PRIVATE BY DESIGN No account, no sign-up. Your wishes stay on your device. Where supported, personalised insights are generated on-device with Apple Intelligence. WHY IT WORKS Budgeting apps count the damage once the money is gone. CutCut works one step earlier, while the decision is still yours. Clarity is available as a monthly or yearly subscription, or as a one-time lifetime purchase.

Verdict
The clearest difference is ads: Stop Impulse Buying at none against Compound.'s shown. Stop Impulse Buying also leads on update cadence (every 3 weeks vs every 8 months). Compound.'s advantage is iOS requirement (18.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.
