This is an independent UX expert review based on my proprietary UX checklist for digital health apps. The checklist is based on findings from user testing of 20 health and wellbeing apps. The apps are reviewed against 70 guidelines in 5 categories:
Onboarding and homepage – checkpoints related to first-time user experience (from sign up flow to reaching the home screen of the app)
Tracking – tracking of users’ health data and/or symptoms
Data visualisation – how well the app uses data from tracking to display and visualise insights, progress and patterns
Content – findability and presentation of content
Support and education – how well the app uses both data and content to guide and educate users

Onboarding and homepage | Guideline #2
Include a prominent button to register for
a new account.
The registration button is clearly more
prominent than Sign in button.
Since most of the users on this screen will be
new users, this is the right approach.
Onboarding and homepage | Guideline #1
Consider delaying account creation until
user has tried the app.
Caria app doesn’t allow users to use the app as
At the point of download, the user doesn’t know
whether the app will meet their needs or not.
The onboarding ﬂow should prioritise
establishing trust over collecting users’
Onboarding and homepage | Guideline #4
Make sure there is a clear and explicit opt-
in to terms and conditions.
Caria app asks users to provide an explicit opt-
checkbox and it isn’t preselected).
Onboarding and homepage | Guideline #8
Explain why you need the data
and how you use it.
The information that anonymised
user data is shared with research
organisations is buried in the Privacy
Policy which isn’t written in a user-
Additionally, the app states that
personalised programme will help
users achieve their goals, however, it
seems that all users are presented
with the same content, regardless of
the goals they selected in the
Onboarding and homepage | Guideline #12
Account for edge cases and when things
aren’t as usual.
User testing showed that people might be
suﬀering from health issues that make the
‘standard’ set of answers irrelevant to their case.
They might also lack the knowledge necessary to
conﬁdently answer those questions. In those
cases, participants typically looked for ‘I’m not
sure’ or ‘I don’t remember’ option to carry on
with the onboarding ﬂow.
Caria app supports these options and explains
the terms used in the questions in case users
were not familiar with them.
Onboarding and homepage | Guideline #19
Keep the home screen simple.
The app’s home screen displays
With this approach, quite a few
diﬀerent things are competing for
An improvement would be to
establish clearer information
priority and display one primary
call to action. This way the core
purpose of the app would be
reinforced on the home screen
and users’ attention would be
focused on the next most
Tracking | Guideline #20
Give people useful pre-sets but allow
them to add custom categories.
Caria app doesn’t allow users to add
custom categories or tags. They do,
however, allow to hide the categories
that the user isn’t interested in.
This allows the user to simplify the
tracking experience by removing
distracting, unwanted categories, and
focus on the things that are relevant to
Tracking | Guideline #25
Streamline the process of
adding entries as far as possible.
The app allows users to create Siri
shortcuts in case they preferred to
add their entries this way.
Regular tracking requires a lot of
eﬀort. You can help users to stay
consistent by making it as
convenient as possible.
Visualising data | Guideline #31
Provide a useful empty state
before enough data is available.
If there are no entries available for the
given period, the app displays a useful
message to prompt the user to log
Visualising data | Guideline #32
Help people understand patterns.
One of the common goals people
have when using health and wellbeing
apps is to understand patterns in
their symptoms and behaviour.
Caria app helps them do that by
displaying a correlation between
symptoms and triggers.
Content | Guideline #41
Provide useful ﬁltering options.
When looking for relevant content, users
often want to ﬁlter the results based on
Caria app doesn’t provide ﬁltering
options. While the list of courses is short
enough for the user to scroll, the recipes
page would beneﬁt from ﬁltering option
to allow users to ﬁnd meals based on
symptoms or dietary preferences.
Support and education | Guideline #52
Provide practical tips related to
Caria app provides articles and
community discussions related to
practical issues women experience
While a healthcare professional
can discuss the medical side of
symptoms, people are often
interested in the practical side of
what is happening to them e.g.
how it aﬀects their work and social
Support and education | Guideline #55
Showcase real experts and coaches.
Caria app allows users to connect with
health coaches and experts.
However, it’s not clear whether the
courses and articles presented in the
app are curated or written by those
experts. If that is the case, it should be
highlighted in the app to build more trust
Support and education | Guideline #57
Make it relevant based on the information
you have received from the user.
The articles presented in the Insight tab are
personalised based on users’ logged symptoms
One of the pain points with health information
online is the eﬀort it takes to sift through it to
ﬁnd the pieces that are relevant to the user and
their situation. By personalising the insight, the
app makes the hard work for them.
Support and education | Guideline #70
If the topic is sensitive, consider allowing
people to post anonymously.
Users have a choice to post anonymously or
add their name. This approach creates a safe
space and encourages users to share their
