Hi there! I understand you feel the SmartBP app isn't tracking your blood pressure automatically and only records what you manually enter, which was not clear to you before purchasing it for £40. Let's see if we can clarify how the app works and how you might get the features you expected.

Just to confirm: Are you using a Bluetooth blood pressure monitor device alongside the app, or are you entering readings manually? The SmartBP app primarily records the blood pressure data you input. If you have a compatible Bluetooth blood pressure monitor and want automatic tracking, the app supports that but it requires connecting the device properly.

Also, do you have the premium version active? Sometimes the free and premium versions differ in features, and restoring your purchase can unlock more functionality. You can check this by opening the app, going to the "More" section, and tapping "Restore Purchase" to ensure premium features are enabled.

Here’s what I suggest:

1. Verify you are using a Bluetooth-enabled blood pressure monitor that pairs with your iPhone.
2. In SmartBP app, check the premium status and restore purchase if necessary (from "More" > "Restore Purchase").
3. Pair your Bluetooth BP monitor with your iPhone via Settings > Bluetooth.
4. In the app, look for a device connection or sync option to link your BP monitor.
5. Once paired, take a measurement with your device and see if the reading automatically appears in the app.

If you don’t have a compatible external device, the app won’t be able to auto-track your blood pressure because it relies on input from your device or manual entries.

If you’re still unsure about your monitor's compatibility or steps to sync, I can guide you through that. Does your blood pressure monitor support Bluetooth or smart features? Let me know!

Are you satisfied with this guidance so far, or would you like me to help you with detailed pairing steps or checking your purchase status?
