Your sensor's value on your phone, on the Lock Screen, on Apple Watch and — with iOS 26 — in the widget area of the CarPlay dashboard. Without opening anything. WHAT IT DOES - The live value, a trend arrow and the last 3, 6, 12 or 24 hours as a curve - Low, high, urgent-low and no-data alerts - Separate thresholds for the night, and a snooze — never for an urgent low - Emergency plan: when the value crosses a line you drew, the message you wrote and a call are one tap away in the Lock Screen notification (up to three contacts) - Friends and family — whatever sensor they wear, in one app; each with their own account - The board: time in range today and this week, a streak, estimated HbA1c - Home Screen and Lock Screen widgets, an Apple Watch app and a watch-face complication - Make it yours: light or dark theme, a colour, a pattern or your own photo - Siri: "What is my glucose in GlucoPop?" - Writing readings to Apple Health — only for the people you tick SENSORS Dexcom G6, G7, ONE and ONE+ · FreeStyle Libre 2, 2 Plus, 3 and 3 Plus · Medtrum TouchCare A6, A7 and Nano · and everything else through Nightscout. GlucoPop does not read the sensor itself; it signs in to your sensor's own service (Dexcom Share, LibreLinkUp, Medtrum EasyView, Nightscout) with your account. Dexcom, FreeStyle Libre and Medtrum are trademarks of their respective owners; GlucoPop is independent and is not affiliated with or endorsed by them. PRIVACY It has no account of its own. Your credentials stay in your phone's keychain (and, while the watch reads for itself, on your paired Apple Watch), your readings stay on your phone, and the app, its widgets and the watch talk to your sensor's service directly. Your credentials and readings never reach us. The one exception is optional and off by default: if you switch on "Wake-ups from the server", our server is told your phone's notification address and nothing else. PRICE Everything is free today. The day I can no longer carry the app's costs on my own, a few advanced features move to a subscription; the live value, the curve and the alerts stay free for good. The alert that warns you about a hypo is not a feature to be unlocked. IMPORTANT GlucoPop is not a medical device and must not be used to make treatment decisions. The values it shows come from your sensor's own service and can be delayed. Confirm with your sensor's official app or a finger-prick, and talk to your doctor before treating. iOS decides for itself how often an app may run in the background. GlucoPop is not an alarm system and does not take the place of the app your sensor came with. When it loses sight of your value, it tells you.

Verdict
The clearest difference is update cadence: GlucoPop at every 3 days against ChronoDiary's every 6 weeks. On price, ads, in-app purchases and device support there is nothing between them.
