Read full description

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 that’s 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 YOU’LL LIKE IT β€’ See what’s still returnable β€” and the total dollars on the table β€” the moment you open the app. β€’ A countdown for every purchase: what’s due today, what’s expiring soon, what’s safe. β€’ Gentle reminders before a window closes, so a deadline never sneaks past you. β€’ Track refunds you’ve recovered, so you can watch the money you didn’t 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 it’s 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 don’t have to look it up. ADD IT TO YOUR CALENDAR Send any return deadline to Apple Calendar with a tap, if you’d 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.
