The things people actually ask before downloading.
What is Midline?
+
Midline is a personal health journal for people managing diabetes. It captures the daily context a glucose chart can't — mood, meals, insulin timing, stress, life events — in 15 seconds a day, so you walk into your next doctor's appointment with three months of organized context on one page. Most diabetes apps track your numbers. Midline tracks the story around them.
Is Midline free?
+
Yes. The full daily journal is free forever — mood and symptom check-ins, blood sugar, meals, insulin, manual entry, pattern insights, and full data export. Premium ($4.99/month or $29.99/year) adds AI-generated doctor summaries, photo-based blood sugar reading, photo-based meal estimation, and Ask My Health conversations. No trial expiration, no bait-and-switch — your data stays on your phone whether you pay or not.
Is Midline a glucose meter or CGM?
+
No. Midline is a journal, not a meter or a continuous glucose monitor. You take your blood sugar reading from a fingerstick meter or a CGM like Dexcom or Libre, and Midline is where you record it alongside the context — what you ate, how you felt, whether you pre-dosed. The numbers come from your devices. Midline gives them a story.
Does Midline give medical advice or replace my doctor?
+
No, and it shouldn't. Midline is a journal with a very good memory, not a medical device. It's not FDA-cleared, it doesn't diagnose, and it never tells you what to do with insulin or food. The whole point is the opposite — it organizes what's been happening in your life so your doctor has the context they need to give you better advice.
Where does my Midline data go? Is it private?
+
It stays on your phone. There's no Midline account to make and no server storing your health data — we never built one. When you use a premium AI feature, the request goes through a stateless proxy, gets a response, and isn't retained. When you want to share something with your doctor, it leaves through your phone's share sheet on your terms. Privacy isn't a marketing claim here; it's the architecture.
Does Midline work with Dexcom or other CGMs?
+
Today, you log CGM readings into Midline manually or by photo — point your camera at the Dexcom or Libre screen and Midline reads the number. You don't get a live data feed yet. Direct CGM integration (Dexcom, Libre, HealthKit) is on the roadmap, and HealthKit support is the most-requested next feature. For now, photo logging keeps it under five seconds.
Is Midline only for Type 1 diabetes?
+
No. Midline supports Type 1, Type 2, gestational, and prediabetes. The journal adapts to what you actually log — if you don't take insulin, the insulin prompts get out of your way. If you're tracking diet-controlled blood sugar, that's the flow. If you're managing blood sugar for any reason, Midline fits.
How does the doctor appointment summary work?
+
On Premium, Midline turns three months of your daily entries into a one-page summary written in plain language — your patterns, what you've been logging, the things worth flagging. You hand it to your endocrinologist or share it through the share sheet before your visit. It's not a clinical report; it's a memory aid. Most people walk in better prepared than they've been in years.
