TapBack: One-Tap Memory

About

Did I lock the door? Is the dog already fed? When did I last change the filter? Where did I put the spare key? Who has my drill? These are too small to justify a note, a calendar event or a whole productivity system — so we carry them around in our heads instead, and then wonder. TapBack is a one-tap external memory for tiny real-world facts. Set a card up once. After that, the normal action is a single tap. SIX THINGS IT REMEMBERS Did I? — Record that you did something. Front door: Locked, 18 min ago. State — Open or closed, on or off, fed or not fed. One tap moves to the next. Last time — When you last watered, changed, cleaned or serviced something. Where — The last place you put something, chosen from your saved places. Count — How many coffees, glasses of water or trips outside. One tap adds one. Who has it — Who has your drill, your spare key or your trailer. BUILT TO BE BORING IN THE RIGHT WAYS • One tap. No second confirmation step and no save button. • A visible Undo for five seconds after every record. • Human times: "Just now", "2 hr ago", "Yesterday · 21:14", "4 days ago". • Full history on every card, with the ability to correct a mistaken record. • Dark Mode, Dynamic Type and VoiceOver from day one. • No streaks, no scores, no guilt. Nothing turns red because you forgot. PRIVATE BY CONSTRUCTION Everything stays on this iPhone. There is no account, no sign-in, no server, no analytics and no advertising. TapBack works with the network switched off, because it never needed it. ONE PURCHASE Buy it once. No subscription, no in-app purchases, no upsells. A NOTE ON WHAT THIS IS TapBack is a memory aid, not a sensor. It cannot see your door, your stove or your medication. It only ever tells you what you recorded and when — never that something is definitely true. That distinction matters, so the app is careful about it everywhere.
