Drive Logic← Glucose Thread
Updated public TestFlight beta
Help make glucose patterns easier to understand.
Glucose Thread brings CGM readings together with food, medications, sleep, workouts, and Apple Health context—so you can review timing, trends, and possible relationships across your day.
No cost · Request validation · No health data requested
About the app
More than another glucose number.
Use trends and daily context to ask better questions about what may be affecting your glucose. Glucose Thread shows associations and timing—not proof of cause and effect.
Notice patterns
Explore 24-hour graphs, longer-term trends, and clearly labeled delayed or stale information.
Stay informed
Keep useful context available across supported iPhone, Mac, Apple Watch, widgets, Lock Screen, and Live Activities.
Who we’re looking for
Simple requirements.
The updated public beta is open now. We are looking for adults who can install it and already use a continuous glucose monitor.
- ✓An iPhone
Your phone must be able to install the current TestFlight build.
- ✓A continuous glucose monitor
Libre and Dexcom users are especially helpful; tell us your exact model in the form.
- ✓Age 18 or older
This recruitment form is for adults participating on their own behalf.
- ✓Willingness to give usability feedback
We want candid feedback about setup, clarity, accessibility, and usefulness—not your medical information.
Private by design
Your health data is not part of recruitment.
Drive Logic does not ask for or receive your glucose readings, insulin doses, medication list, diagnoses, medical records, or CGM credentials through this page.
Read the full Glucose Thread privacy notice →App data stays on your Apple devices and, if you enable synchronization, in your private iCloud account.
LibreLinkUp, Dexcom Share, and optional AI-provider credentials are stored in Apple Keychain, not in the recruitment database.
Drive Logic does not sell health information or recruitment contact details, and does not use them to build advertising profiles.
The app contacts a CGM-sharing service only after you configure it. Optional external AI is used only when you configure a provider and choose content for a request.
Technical diagnostics may include app version, device type, error category, and timing. Credentials and Apple Health data are excluded.
Your name, email, Apple device, reason, and consent timestamp are stored only to manage this beta. Genuine requests are enrolled through App Store Connect and summarized to the Glucose Thread team.
Important safety boundary
Glucose Thread is a personal recordkeeping and visualization tool. It is not a medical device, medical alarm, dosing tool, or substitute for your official CGM app, approved device, care plan, or professional medical guidance. Readings, estimates, and trends can be delayed, incomplete, or inaccurate. Never use Glucose Thread to calculate insulin or medication doses or make treatment decisions.
