Return Window Radar is the quiet, private way to make sure you never miss a return deadline β or leave a refund on the table. Most of us lose money the same way: we mean to return something, the window quietly closes, and thatβs that. Return Window Radar watches every return window for you and shows, at a glance, exactly how much money you can still get back. Everything stays on your iPhone. No account. No cloud. No tracking. WHY YOUβLL LIKE IT β’ See whatβs still returnable β and the total dollars on the table β the moment you open the app. β’ A countdown for every purchase: whatβs due today, whatβs expiring soon, whatβs safe. β’ Gentle reminders before a window closes, so a deadline never sneaks past you. β’ Track refunds youβve recovered, so you can watch the money you didnβt lose add up. SCAN A RECEIPT, DONE Scan a receipt with your camera β or pick one from Photos β and Return Window Radar reads it on-device and fills in the store, date, and total for you. Snap it, confirm, and itβs tracked. KNOWS THE POLICIES Add a store and the app suggests its return window automatically from a built-in catalog of common retailers β so you donβt have to look it up. ADD IT TO YOUR CALENDAR Send any return deadline to Apple Calendar with a tap, if youβd rather be reminded there. PRIVATE BY DESIGN Return Window Radar has no servers and no analytics. Your purchases, receipts, and reminders live only on your device and are never uploaded β receipt text recognition happens entirely on-device. Stop giving away money you could get back. Put your returns on the radar.
