What the app does, who it is for, and what you can track.
Glucose helps you record and understand blood glucose and related health information in one place. You can add readings, review trends, manage medications and reminders, connect supported devices, share supported entries with Apple Health, and create reports for your healthcare provider.
Glucose is designed for people who want a clearer record of glucose and related health information, including people managing prediabetes, Type 1 diabetes, Type 2 diabetes, gestational diabetes, or another metabolic condition. It can also be used as a general health log.
No. Glucose and its insights are for informational purposes only. The app does not measure blood sugar, diagnose a condition, or recommend insulin doses. Always consult a qualified healthcare professional before changing medication or making treatment decisions.
Glucose can record blood glucose, carbohydrates and meals, insulin, A1C, blood pressure, heart rate, weight, ketones, medications, temperature, exercise, blood oxygen, notes, and INR. The exact log types available can vary by app version. You can hide log types you do not use from Settings under Show/Hide Log Types.
No. You can use Glucose and save records locally without creating an account. An account is recommended if you want supported glucose history and medication records backed up and synced across devices.
Add readings, correct records, and choose the right units.
Open the History tab and tap the + button or floating quick-add button. Choose Glucose, enter your reading, and optionally add insulin, tags, notes, or a different date and time. Tap Save when you are finished.
Tap a record in History to open and edit it. To delete a record, swipe left on it and choose Delete. Review the record before deleting it because deleted records cannot currently be restored from within the app.
Yes. Go to Settings, open Preferences, and choose Change glucose unit. Select mg/dL or mmol/L. Glucose displays, target ranges, graphs, and supported alert values will use the unit you select.
Connect supported sources and troubleshoot missing readings.
Go to Settings and open Connect Bluetooth Meter, then tap the + button. Choose your exact device in the setup guide and follow its pairing instructions. Keep Bluetooth enabled, the meter close to your iPhone, and the meter in its required pairing or transfer mode.
The in-app catalog includes devices from several major manufacturers, but a device appearing in your profile does not necessarily mean it supports direct Bluetooth syncing. The current source of truth is the device list inside Settings under Connect Bluetooth Meter. If your exact model is not shown there, request the device or contact support before relying on an automatic connection.
Yes. Open Settings and Apple Health Settings to review the data categories and read or write permissions available in your version of Glucose. You stay in control of each Apple Health permission. If access was previously denied, use Manage Access in Apple Health or iOS Settings to change it.
Glucose can work with supported CGM connection methods shown in the app. Available devices, status details, alerts, and data-sharing routes can vary by model, region, permissions, and app version. Confirm your exact CGM in the current Connect Bluetooth Meter setup guide before depending on automatic readings.
Check that Bluetooth is on, Glucose has Bluetooth permission, the device is charged and nearby, and it is in the correct pairing or transfer mode. Confirm that the device still appears in Connect Bluetooth Meter and review Apple Health permissions if that is part of your setup. Keep Glucose open during initial pairing or sensor warm-up. If reconnecting fails, send debug diagnostics to support and include the exact brand and model.
Share useful summaries, move devices, and manage your plan.
Open Report for a doctor from Settings or choose Create Report from Insights. Select PDF or CSV, the reporting period, the log types to include, the sorting order, and any available averages or personal details. Tap Next to generate and share the report. Some reporting options may require a subscription.
Go to Settings and choose Login/Signup to Sync Data. Create an account, then sign in with the same account on another device. Pull down on History to request another sync. Supported glucose logs and medication records sync with the account; preferences, report templates, reminders, and other locally stored settings may need to be configured again.
Manual logging and basic history are available without a subscription. Advanced insights, longer graph ranges, sharing tools, reports, AI-assisted features, additional statistics, and customization may depend on the current plan. The purchase screen in Glucose is the source of truth for the current feature list, price, billing period, and any trial.
Make sure the device is signed in to the same Apple ID used for the original purchase, then open Settings in Glucose and choose Restore Purchase. If no purchase is found, verify the Apple ID in the App Store and confirm the subscription is active in Apple’s subscription settings.
Open Settings and choose Email Support or Help & feedback. For a technical problem, use Send Debug Diagnostics when available and attach the generated file. You can also email hello@glucoseforiphone.com. Include your iPhone model, iOS version, Glucose version, and the exact meter or CGM model for a device-sync issue.
