$35 Bluetooth Blood Pressure Monitor Works with Android and iOS
People with hypertension or other heart conditions may want to monitor their blood pressure daily, and since I was asked recently, I studied blood pressure monitors available on the market from Chinese websites. The simplest ones that simply display the results on an LCD are quite inexpensive since they cost about $15 shipped, unless you buy brands like Omron. You’d then need to enter the data in a spreadsheet or on paper after each measurements, so you’d rather have the process more streamlined, you could consider a Bluetooth version that will automatically keep measurements stored in your Android or iOS smartphone, such as the model below that sells for around $35 on Aliexpress and Ebay.

You’ll need to download “Bluetooth BP monitor” app for Android or iOS, and pair the monitor with your mobile device over a Bluetooth connection using 00000 pin key. The reviews are not so positive for the Android app due to a lack of timezone support.
The app will also let you get the historical results in text format to send by email. The unknown with this type of inexpensive device is the accuracy, but it could be easily tested during your next doctor visit.
If you don’t feel like buying a brandless medical device, but don’t want to spend $100+ on an Omron blood pressure monitor, Xiaomi has also launched iHealth Bluetooth blood pressure monitor going for $50, but it has no display, and only supports Android for now.
