Picture a Tuesday morning. Your mum has her tablets lined up on the kitchen bench, but she can't remember whether she's already taken the blue one. She rings to ask. You're in a meeting, so she waits. By lunchtime she has either taken it twice or not at all, and neither of you is quite sure which.
For many families living with dementia, this is the hard part. It's rarely one big moment. It's a steady stream of small uncertainties. Did I take it? Is the appointment today or Thursday? Has anyone called?
The phone in her handbag can help answer a surprising number of those questions.
This article covers four things:
what mobile technology can realistically do for someone living with dementia
what the research says
what to look for in an app
how to introduce one without it becoming another thing to worry about
What does the research say about smartphones and dementia?
Researchers have found encouraging signs, with some honest caveats.
A 2022 systematic review published in Innovation in Aging looked at 28 studies on how older adults use smartphones and tablets as memory aids. It covered people both with and without cognitive impairment. The researchers found modest evidence that these devices can support memory, including for people living with dementia.
Participants also found smartphones and tablets acceptable, enjoyable and less stigmatising than traditional assistive devices. That last point matters. A phone looks like everyone else's phone.
The same review was clear about the barriers:
Older adults vary a lot in digital confidence.
Many apps don't account for changes in eyesight, hearing or dexterity.
Clinicians and researchers have had too little say in how these tools are designed.
Much of the evidence also comes from case studies and small trials. So it's fair to say mobile technology is promising rather than proven.
In practice, the right tool, set up well, can make daily life easier. The wrong tool, or a good tool introduced badly, usually ends up unused in a drawer.
Where mobile technology helps most
Medication and appointment reminders
Remembering medication is one of the most common reasons families look for help. Alzheimers.gov suggests simple options like a weekly pillbox, a pillbox with an alarm, or an automated dispenser.
A phone reminder builds on the same idea and adds flexibility. It can:
go off at the right time
show which medication to take
let the person confirm they've taken it, which answers the "did I or didn't I?" question for everyone
The same approach works for appointments. A reminder the day before and another an hour before gives someone time to get ready without feeling rushed.
Staying connected with family and friends
People living with dementia can easily become isolated, especially if they live alone. The National Institute on Aging recommends using smartphones and tablets for video calls and messages. It also suggests choosing products that are easy to use, such as phones that let you dial by tapping a photo.
Some devices are built entirely around this idea. The RAZ Memory Cell Phone has a single screen of contact photos, and a family member manages the settings from their own phone.
Keeping the day steady
When memory is changing, having the same shape to each day helps. Regular prompts can cover meals, drinking water, a walk or a favourite radio programme.
When the reminder comes from the phone rather than a family member, it can also take some tension out of the relationship. Nobody likes being nagged, and nobody likes doing the nagging.
Giving families a clearer picture
Families often tell us the hardest part of supporting someone from a distance is simply not knowing. Was today a good day? Did Dad eat lunch?
A care partner might be able to see that the morning reminders were acknowledged or that a daily check-in was done. Then they can stop ringing four times a day and save their calls for real conversation.
Better conversations at appointments
Appointments are short, and memory is often the very thing being discussed. A doctor gets far more to work with than "I think I've been fine" when someone brings a record of:
how they've been feeling
how they've been sleeping
any changes family members have noticed
Elli Cares brings these pieces together in one app. Older adults get medication, appointment and daily reminders, including video reminders recorded by someone they know, along with a simple daily wellbeing check-in. Family members in the shared care circle can see how the day is going, add their own observations, and download a report to take to the next appointment. See how Elli supports seniors and families.
What to look for in a dementia-friendly app
Not every app designed for older adults works well for someone living with dementia. A few questions help separate the useful from the frustrating.
Is it simple? Look for large text, clear buttons and only a few screens. If you need a tutorial to find the main feature, it's probably too complicated. Our article on universal design and accessibility goes into more detail on what good design looks like.
Does it use familiar faces and voices? A reminder recorded by a daughter or grandson carries more weight than a generic beep.
Can family help from a distance? If a care partner can set up and adjust reminders remotely, the person living with dementia doesn't have to manage the settings themselves.
Does it respect independence? The goal is support, not surveillance. Look for tools that keep the person in charge of their own day. Any information shared with family should be shared in a way everyone has agreed to.
Does it work on a phone they already own? Learning a new device and a new app at the same time is a lot to ask.
Is it honest about what it doesn't do? Reminder and support apps are not emergency response services. If falls or wandering are a worry, those need their own plan.

How to introduce a new app without overwhelming someone
The NIA's guidance includes a piece of advice worth repeating: whatever technology you choose, start early. That leaves time to learn it and build it into a routine. A new habit is much easier to form in the early stages of dementia than later on.
A few approaches tend to help:
Start with one thing. One daily medication reminder is enough for the first week or two. Add more once that feels normal.
Set it up together. Sit side by side, let them hold the phone, and talk through what each reminder is for.
Record the first video reminder together. Hearing a familiar voice makes the app feel personal from day one.
Check in after a fortnight. Ask what's working and what's annoying, then adjust.
Look for local help. The NIA suggests asking your local library or community centre about technology classes if confidence is low.
What mobile technology can't do
Apps are a support, not a substitute for people. They don't diagnose, they don't replace a doctor's advice, and they won't notice everything.
If you're worried about changes in memory or behaviour, talk to your loved one's doctor. In the US, the Alzheimer's Association 24/7 Helpline is available on 800-272-3900 for families who need information or someone to talk to.
Think of technology as one part of a wider circle of support that includes family, friends, neighbours and care professionals.
Where this is heading
Researchers are also exploring how everyday signals might reveal early changes in health. One example is walking patterns picked up by a phone or smartwatch. It's early work, but the direction is hopeful: technology that supports people quietly in the background rather than asking them to do more. Our article on walking steadiness explains one of these signals and why it matters.
For now, the most useful thing mobile technology can do is simpler. It can help someone take the right tablet at the right time, see a familiar face at the end of the day, and feel a bit more in charge of their own life. For families, it can turn a stream of worried phone calls into a clearer, calmer picture of how things are going.
