HomeHistory: Log for HomeKit

HomeHistory keeps the history of your Apple Home accessories and charts it the way the Health app charts your steps. A spare iPad (iPadOS 16 or later) or a Mac (macOS 14 or later) becomes the Hub. It records every reading and change: temperature, humidity, light level, air quality, CO₂, PM2.5, battery level, brightness and thermostat targets; every door and window opening, motion, occupancy and lock change; every switch turned on or off. Your iPhone, other iPads and Macs show that history, synced through your own iCloud. WHAT YOU GET • Day and week charts for each sensor it records: lines break where nothing was recorded, and a coverage bar shows how much was • Month and year views: readings' low, average and high by the hour for a month, by the day for a year (Full) • An event list: when the door opened and for how long, how long the lights were on • Up to four rooms on one chart (Full) • Export to CSV or JSON (Full) • A wall dashboard on the Hub: live values, 24-hour lines, and controls for lights, brightness and thermostat targets • Night Mode for the wall iPad, and Guided Access support • Widgets on iPhone and iPad • °C or °F, in English, German, Dutch and French HOW IT RECORDS HomeKit gives apps no history, so the Hub keeps it. An iPad records while HomeHistory stays open on its screen: iPadOS stops apps in the background, so the app keeps the screen on, and dims it at night if you like. A Mac keeps recording while you use other apps. Every chart shows how much of its time was recorded. NO SERVER, NO ACCOUNT Your history stays on your devices and in your private iCloud database, which the developer cannot see. HomeHistory has no server, no account and no analytics. Its privacy label is "Data Not Collected", and Settings › About › Transparency explains how to check that with a network monitor. FREE AND FULL Free shows the last 7 days, records with one Hub, and shows one home and two dashboard rooms; widgets show your first series. HomeHistory Full is a one-time purchase that unlocks all your history, including what was recorded while you used the free version, any number of Hubs, every room and home, export, room comparison and any series in widgets. No subscription. One purchase covers your iPhone, iPad and Mac, and Family Sharing shares it. HOW IT WAS MADE HomeHistory is made by one developer working with an AI coding assistant, Claude by Anthropic. The AI is not part of the app and never sees your home. The room photos in some screenshots are AI-generated; the app screens are real. The Transparency page in the app says exactly what that means. You need Apple Home accessories, and an iPad or Mac that stays on to record.
