What does Diabetes Hacker actually do?
Snap a photo of your meal, enter how many units you bolused, and the app pulls your blood glucose from Dexcom for the next 3 hours. The journal shows what happened to your sugar after every meal — over time you build a real memory of how foods affect you.
My Dexcom won't connect.
Open Settings inside the app → Connect to Dexcom. Use the same username and password you use for the Dexcom Share / Follow app. If you can log in there and still can't here, email me and I'll dig in.
I logged a meal but there's no 3-hour chart for it.
Usually this happens when you log a meal right after opening the app, before your BG number has finished loading from Dexcom. The app backfills the chart in the background as long as you open it within ~24 hours of the meal — just sit on the home screen for ~30 seconds with Dexcom connected and it'll heal itself. If the meal is older than 24 hours, Dexcom's API has already rolled off the data and it's gone.
The home screen takes a minute to show my BG. Is that normal?
Yeah — Dexcom Share takes a few seconds to authenticate the first time per app session, then refreshes every 30 seconds after that.
Does the app tell me what to bolus?
No. It's a logging and tracking tool, not a medical device. It shows what happened so you (with your healthcare provider) can decide better next time.
Do I need a Dexcom?
A Dexcom Share connection is what powers the automatic 3-hour glucose chart. You can still log meals and bolus units without it, but the response chart depends on Dexcom data.
What about FreeStyle Libre, Medtronic, or other CGMs?
Right now: Dexcom Share only. Other integrations are on the roadmap — email me if you want one prioritized.
Can I edit a past meal entry?
You can swipe to delete entries in the Journal, and tap the time at the top of a meal to fix a wrong timestamp. Full editing is on the roadmap.
How do I export my data?
In the Journal, tap the share icon in the top right. The app generates a CSV of all your meals — send it via Mail, AirDrop, save to Files, whatever you want.
How do I delete all my data?
Delete the app from your iPhone. Everything is stored locally — uninstalling wipes it for good. The app doesn't sync to iCloud.
Privacy?
Your meal log and Dexcom credentials stay on your device — there's no Diabetes Hacker server. The only thing that leaves your phone is the request to Dexcom's own servers when you have Dexcom Share connected. Full details in the Privacy Policy.
