Why patients stop using health apps after week two, and how design keeps them
Most health apps lose their users within two weeks. The research on why patients drop off, and a design framework to keep them, with lessons from Elli Cares.
Short answer
Patients stop using health apps when the app asks for more than it gives back. Logging takes too long, nothing visibly changes, reminders turn into noise and nobody else is in it with them. Design keeps them by cutting effort to a tap, showing progress they care about, timing reminders well and bringing family or clinicians in.
Day one is lovely. The download is fresh, the onboarding is friendly, and the patient dutifully logs their mood, their medication and their sleep. Day three, they log two out of three. Day nine, a reminder arrives during dinner and gets swiped away like a wasp. By day fourteen the app lives on the third home screen, next to the airline app from last summer.
That isn’t a hunch. In a panel-based analysis of 93 mental health apps, Baumel and colleagues found a median 15-day retention of 3.9% and a 30-day retention of 3.3%. Nearly everyone who installed those apps had quietly left before the end of week two.
At Dtail Studio, a Barcelona design studio working with HealthTech and renewable energy startups, we spend a lot of product time on that second week. Much of what we know about it comes from designing Elli Cares, an app for people living with cognitive impairment and their families (Elli Cares case study).
Why do patients stop using health apps?
Because opening the app keeps getting more expensive while the reward stays the same. Patients tell researchers the same things again and again: it takes too long, they get bored, it costs more than they expected, it’s confusing, and they don’t trust what happens to their data.
In a US national survey, Krebs and Duncan found that 45.7% of people who had downloaded health apps had stopped using some of them. The top reasons: data entry taking too long (44.5%), losing interest (40.5%), hidden costs (36.1%), confusing apps (32.8%) and not liking how data was shared (29.0%).
Read that list again. Almost every item on it is a design decision someone made in a meeting.
Why is week two the drop-off point?
Week one runs on novelty. Week two runs on habit, and most apps haven’t built one yet. The curiosity has worn off, the results aren’t visible, and the app still asks for exactly the same effort it asked for on day one.
It isn’t just a consumer app problem. A meta-analysis of app-based interventions for chronic disease found pooled dropout of 43%, rising to 49% in real-world observational studies. Those were people who signed up for research, often with someone checking in on them. An app store download comes with no such moral support.
Does a prescription fix it?
No. A prescription gets the app onto the phone. It doesn’t make anyone want to open it.
Germany is the clearest test, because its DiGA scheme lets doctors prescribe approved health apps that insurers pay for. A 2025 survey of 246 patients at German rheumatology clinics found that 72.4% were willing to use a DiGA at least weekly, yet only 39.8% had heard of them and 12.6% had ever used one.
The willingness is there. The gap sits in awareness, recommendation and the first few weeks of use, which is exactly where design and onboarding earn their keep. The first minute gets its own post: HealthTech onboarding, consent, permissions and trust in the first 60 seconds.
Reason people drop off, and the design response
Here’s the scorecard we use when we audit a health app. The first five come straight from the Krebs and Duncan survey. The last three are patterns we keep seeing ourselves.
Logging takes too long (44.5%).
In the app: forms with eight fields, free text and a save button at the very bottom. The fix: one-tap entries with sensible defaults, under ten seconds, and pull in what the phone already knows.Lost interest (40.5%).
In the app: it collects and collects, and never says anything back. The fix: give something back on every visit, like a pattern, a streak or a short weekly summary in plain words.Hidden costs (36.1%).
In the app: the paywall appears after a week of carefully entered data. The fix: show the price, or that it’s reimbursed, before setup starts.Confusing to use (32.8%).
In the app: lots of features shouting at the same volume, low contrast, medical jargon. The fix: one main action per screen, clear hierarchy, high contrast, everyday words.Worried about data sharing (29.0%).
In the app: vague permission prompts and no idea who sees what. The fix: say who sees each piece of data, in one sentence, at the moment it matters.Reminders become noise.
In the app: generic notifications at fixed times, several a day. The fix: fewer reminders, each one actionable, timed around the patient’s actual day.Nothing has changed.
In the app: the home screen looks the same on day 1 and day 30. The fix: a home screen that reflects today, with what’s next, what’s done and what improved.The patient is alone in it.
In the app: only the patient can see or do anything. The fix: bring in a caregiver or clinician, with clear and limited permissions.
If your app shows more than two of these symptoms, your retention problem is probably a design problem wearing a growth hat.
What does good re-engagement design look like?
It looks like an app that gets lighter over time. Week one can ask questions. By week two, the app should know enough to ask less and show more.
A few patterns that work:
Reminders that carry the action.
“Take your 9:00 tablet” with a Done button beats “Don’t forget to check in!”, which only adds a step.A rhythm that matches the condition.
Not every health app needs a daily open. A weekly check-in people actually do beats a daily one they ignore.Progress in the patient’s terms.
“You slept better on days you walked” means more than a chart with seven unlabelled bars.Someone else in the loop.
The chronic disease meta-analysis found lower attrition among people who wanted to be involved in their care, and among interventions using more than one channel. Shared care gives the app a second reason to be opened.
Regulated products don’t get a pass on any of this. If anything, clinical requirements push you towards clearer screens, which we argue in why healthcare UI regulation makes products better.
Elli Cares: designing for the people who use it every day
The Elli App is for people living with cognitive impairment and their families. When we started working together in November 2023, the problem was clear: high cognitive load, low contrast and an unclear hierarchy. For someone living with dementia, every extra decision on a screen is a reason to put the phone down.
So we took decisions away. We simplified the flows, moved to a high-contrast interface and built a calm visual language across the website, platform and app. The features are the everyday ones: reminders, mood tracking, scheduling, location and messages with caregivers. That last one matters here, because the Elli App is designed for the person and the people around them. We’ve written more in designing for patients and caregivers and designing apps for dementia.
The Elli App is used in 19 countries.
“Working with Dtail felt like having a senior team that truly cared about results and users.” Angela Edwards, CEO, Elli Cares
We don’t publish retention numbers for client products. What we can say is that designing for people with cognitive impairment raises the bar for everyone. If an older user with memory loss can log their mood in one tap, so can a busy 35-year-old on a train. More on that in designing tech for older adults.
FAQ
What is a good 30-day retention rate for a health app?
There’s no single benchmark. One large analysis of mental health apps found a median 30-day retention of 3.3%. Define “active” by what your treatment needs, weekly or daily, then compare your cohorts with each other.
Do push notifications help or hurt retention?
Both. A reminder that lets the patient finish the task from the notification helps. Generic nudges several times a day teach people to swipe you away.
Should patients use a health app every day?
Only if the condition needs it. Match the rhythm to the care plan. A weekly check-in people do is worth more than a daily one they skip.
Do caregivers improve engagement?
Research on chronic disease apps links lower dropout to people who want to be involved in their care and to interventions with more than one channel. A caregiver gives the app a second reason to be opened, as long as permissions are clear.
Is a prescribed app (DiGA) easier to retain?
Easier to get installed, not easier to keep. German survey data shows high willingness but low awareness and use, so the first weeks still depend on design.
The fourteen-day test
Install your own app on a clean phone and use it as a patient for fourteen days. Every time it asks you for something, make a mark in one column. Every time it gives you something useful, make a mark in the other. If the first column is winning by day seven, congratulations: you’ve found your week-two problem before your patients did.
Losing patients after week two? We’d happily take a look with you.
