Five health apps that actually make sense for people over sixty

The apps in the stores are mostly aimed at fit twenty-year-olds. These aren’t. Simple step counters, blood pressure logs, and one food tracker that shows most older adults they aren’t eating enough protein.

A lot of the health-tracking apps in the app stores are aimed at fit people in their twenties who want to log gym workouts and see charts of their macros. That is not the audience for this piece. What we need — what my residents actually use, what their families actually use — is something simpler. Big fonts. Automatic tracking wherever possible. Data you can print out or hand to a doctor. Ideally something a person who has never touched a smartphone before can figure out inside an afternoon.

There aren’t as many of these as you’d hope. But there are enough. Here are five that hold up.

Why a phone can be useful at all

The gap between average life expectancy and healthy life expectancy is around nine years for men and twelve for women in Japan. Most of what closes that gap is small daily adjustments — walking a little more, blood pressure trending down instead of up, weight steady rather than climbing. The only way to know whether the daily adjustments are producing anything is to measure. That used to mean a paper notebook, which most people abandoned after a month.

A phone in your pocket, if it’s counting your steps whether you asked it to or not, and if you tap in your blood pressure reading once a morning, produces graphs that show trends even the doctor can’t easily see over the course of a fifteen-minute appointment. That is the modest but real value of these apps.

Five that work

Aruku365 (Walk 365)

A Japanese step-counter app designed with older adults specifically in mind. Big buttons. Big numbers. It doesn’t try to do everything — just steps, walking time, and a simple monthly view. You can join walking events organized by municipalities and companies, which some people enjoy and some ignore. Free. Available on both iOS and Android.

The virtue is that it’s not overwhelming. If someone in their eighties has never used a health app, this is the one I’d start them with.

Apple Health (iPhone)

If your phone is an iPhone, an app called Health is already installed. You don’t have to download anything. Carry the phone, and it counts steps, tracks distance, and estimates activity. You can manually add blood pressure, weight, and sleep data, and it will graph them for you.

The best feature for older adults: you can share your Health data with family members or with participating clinics. Some Japanese hospitals now accept data uploads directly from Apple Health during appointments, which is faster than reading a paper log to the doctor.

Google Fit (Android)

The equivalent for Android phones. Automatic step counting. Two custom metrics — Move Minutes and Heart Points — that were designed with the WHO physical activity guidelines in mind. You get points for movement that gets your heart rate up. Not gamified in an annoying way — just a simple daily target.

Both Apple Health and Google Fit work in the background without draining your battery noticeably, and the data quality is high enough to be useful for tracking real-world walking.

Ketsuatsu Note (Blood Pressure Notebook)

For people whose family doctor has asked them to log home blood pressure readings, this is the app I’ve seen used most. Enter your morning and evening reading, and it makes a graph automatically. It also generates a printable summary you can bring to appointments — which doctors love, because it saves them the fifteen minutes it would otherwise take to read a handwritten log.

If you’re on blood pressure medication and your doctor is titrating the dose, the print-out from this app is genuinely useful. Free.

Asken

Food logging. Take a photo of your meal or search for what you ate, and the app estimates the calories and major nutrients. It also flags whether you’re low on protein or short on vegetables that day.

For older adults specifically, the value is different than for younger dieters. Most older adults are undereating, not overeating — particularly on protein — and Asken shows this quickly. If your log says you’re hitting 45 grams of protein a day and your body needs 65, that’s a signal to add an egg to breakfast. That is the sort of adjustment that matters at seventy.

What to actually do with any of them

Pick one. Not five.

The mistake almost everyone makes with health tracking is trying to log everything at once. Sustained is better than comprehensive. If you can only stick with one thing, steps is the highest-yield choice, because it comes automatically once your phone is in your pocket.

Second highest yield is morning blood pressure, if it’s a concern. It takes 30 seconds to enter, and the trend line over months is exactly what your doctor needs.

Third is a food log during specific investigative periods — say, four weeks to see whether you’re really getting enough protein. Then stop logging once you know. Food logging every day forever is unsustainable and, in older adults, sometimes counterproductive.

Two setup tips

Increase the font size in your phone’s system settings. All these apps inherit the system font size, and the default is too small for most people over sixty. Setting → Display → Text Size on iPhone; similar on Android. You’ll appreciate this in every app you use, not just the health ones.

Turn on the app’s summary widget or lock-screen display, if it has one, so you see your daily steps every time you check your phone. Visibility drives habit.

What these apps are not

They are not medical devices. The step count is accurate enough for tracking trends. The heart rate reading from a phone camera is approximate. Sleep tracking on your phone is a rough estimate at best. None of these should replace a doctor’s assessment or a proper measuring device — a validated home blood pressure monitor for hypertension, a proper scale for weight.

What they can do is give you enough continuous information to notice when something is drifting, before the annual health check tells you it has already drifted for a year. That is a modest goal, and it’s a valuable one. Start with one app. Stick with it for a month. Then decide whether to add anything.
