How I Made a Mobile App for Tracking Blood Pressure Using MongoDB Realm and Xamarin
summary
A cross‑platform blood‑pressure tracker is built with Xamarin.Forms (migrated toward .NET MAUI) using MongoDB Atlas + Realm for local device storage and automatic sync, email/password auth, a trigger/function that inserts new users into an Atlas users collection, and RealmObjects that map C# properties to MongoDB _id/ObjectId. Readings save in transactions and sync by user partition, charts embed via a single webview URL to MongoDB Charts, and the app works end‑to‑end except for a MAUI display bug with list rendering. The chart integration is one line of code and the entire app is a few hundred lines.
