Wearables, health data and apps — what helps and what doesn’t.
Wearables & Health Data
- GuideWhat Twikka does with your health dataApps should ask your permission before they read data from Apple Health or Health Connect, and you choose what to allow. Who else sees your data depends on the app, so read what it says about sharing. You can take permission back later, but that may not delete data already collected.
- GuideUsing a tracker well, and its limitsA tracker helps most people move a little more, especially if you're not yet active, and it works best with one small goal and some support. Treat its numbers as a rough guide, look at trends rather than single days, and expect your interest to dip.
- GuideUnderstanding your dataTreat tracker numbers as rough guides and look at patterns over time, not single days. Heart rate can help you judge effort, but the talk test works without a device. Wrist heart rate is fairly dependable, sleep stages are the roughest reading, and sleep apps are no substitute for tested treatment.
- GuideTracker accuracyTrackers give rough guides, not exact figures. Step counts can be off in either direction, wrist heart rate is the most dependable measure, and calorie estimates are the weakest. Use them to watch your own pattern over weeks, and go by how your body feels.
- GuideThe future of wearablesWearables are expected to move towards personalised, real-time coaching, but for now that is mostly a projection. Today, trackers are linked with more steps, and they seem to work best with feedback or support. Treat one as a helpful tool, not a requirement.
- GuidePrivacy and your health dataWearables and health apps often collect and share more of your data than you might expect, and removing your name doesn't make data fully anonymous. Read the privacy information, choose the most private settings, protect your phone with a password, and don't treat a high rating as proof an app handles your data well.
- GuideChoosing a fitness trackerChoose a tracker you find comfortable and easy to use: a clear screen, buttons you can press, a strap that suits your wrist and battery life you can manage. Steps and active time are its most dependable numbers; treat calories, sleep and score figures as rough guides.
Apps
- GuideChoosing apps you can trustLook for an app that names who made it, where its health advice comes from and what it does with your data, because many health apps give little evidence that they work. Try free options first, and start with one app that lets you set goals and see your progress.
- GuideMindfulness and nutrition appsMindfulness apps may ease everyday stress a little, but the effects tend to be small and short-lived. Food-tracking apps are linked with weight loss in some research, but many people stop using them. Keep both simple, and drop either if it isn't helping.
