Frequently asked questions
How do I connect FreeStyle Libre?
In the FreeStyle Libre app open Menu → Connected Apps → LibreLinkUp and invite your own email address. Install LibreLinkUp, create an account with that email and accept the invite. Then in DiaFitus go to Settings → Glucose sensor and sign in with the LibreLinkUp email and password. Your login is stored only in your iPhone's Keychain.
How do I connect Dexcom?
In the Dexcom G6, G7 or ONE+ app open Connections (or Settings) → Share and turn Share on. Then in DiaFitus go to Settings → Glucose sensor, choose Dexcom, sign in with your Dexcom account and select your region. Alternatively, readings your sensor app writes to Apple Health are picked up automatically (Dexcom may add a delay).
My glucose isn't showing or is out of date
DiaFitus refreshes every 5 minutes while the app is open, and iOS decides when to refresh in the background. Open the app to refresh. Check that Share / LibreLinkUp is still on and that your sensor app is syncing. Third-party services occasionally change; if sign-in suddenly fails, update DiaFitus and contact us.
Are DiaFitus alerts a replacement for my CGM alarms?
No. Keep the urgent low/high alarms in your Libre or Dexcom app switched on. DiaFitus alerts are a helpful extra, but iOS controls background timing and they can be delayed.
How do I restore my data on a new iPhone?
Install DiaFitus, sign in with the same Apple ID you used before, and your workouts, logs and settings will be restored from your account backup. CGM readings come back from Libre, Dexcom or Apple Health, and CGM logins must be entered again.
How does the AI food scanner work and how accurate is it?
Take a photo of your meal or nutrition label. The AI estimates carbs, fibre, protein, fat and calories, which you can edit before saving. Estimates can be wrong, so always check them before calculating an insulin dose.
How do I post workouts to Strava?
Go to Settings → Strava, connect and approve access. After a workout you can post it, including the muscle map or route image. You can disconnect at any time.
Why aren't notifications arriving?
Check iOS Settings → Notifications → DiaFitus and that Focus modes aren't silencing it. Notifications don't work in the iOS simulator.
Which iPhones are supported?
iPhone running iOS 17 or later. The Apple Watch app needs a paired Apple Watch.
How to delete your account and data
You can delete your account and all data inside the app:
- Open DiaFitus and go to Settings → Coach account.
- Tap Delete account and confirm.
This permanently removes your account, profile, backup (including meal photos), personal programs, coach messages, check-in answers, coach notes, feedback and push tokens. Data you saved to Apple Health stays in the Health app until you remove it there (Health → Sharing → Apps → DiaFitus). Also revoke Sign in with Apple if you wish under Apple ID settings → Sign-In & Security → Sign in with Apple.
Can't open the app? Email support@diafitus.com from the email address linked to your account and ask us to delete it.
