iOS vs Android
iOS has an edge on providing secure apps over Android:
“The risk of malicious apps tends to be higher on Android because it’s
a more open operating system. It’s incredibly difficult to download an
app that isn’t from the Apple App Store on an iOS device, which is one
of the benefits of the company’s walled garden approach.

"Android’s open Google Play Store marketplace has far more apps to
choose from than on Apple's App Store, but there’s a far greater
chance that hackers can make it onto the platform to distribute
malware through malicious apps.
On numerous occasions, highly ranked apps with hundreds of thousands
of downloads from the Google Play Store have been discovered to
contain Android malware.

"Android operating system Popularity: The Android operating system is
hugely popular. This means that developers are constantly building new
apps designed to run on the system. That’s good for users ... mostly.
The problem comes when hackers create apps designed to infect your
mobile devices.
There is an app review process for Google Play. Unfortunately, the
process is far less stringent than what developers face when adding
apps to Apple’s App Store.
It's easier, then, for malicious apps to sneak onto the Google Play
store and easier for users to accidentally install one."

F-Droid
We do not currently recommend F-Droid as a way to obtain apps. F-Droid
is often recommended as an alternative to Google Play, particularly in
the privacy community. The option to add third-party repositories and
not be confined to Google's walled garden has led to its popularity.
F-Droid additionally has reproducible builds for some applications and
is dedicated to free and open-source software. However, there are
notable problems with the official F-Droid client, their quality
control, and how they build, sign, and deliver packages.
Due to their process of building apps, apps in the official F-Droid
repository often fall behind on updates. F-Droid maintainers also
reuse package IDs while signing apps with their own keys, which is not
ideal as it gives the F-Droid team ultimate trust.
Other popular third-party repositories such as IzzyOnDroid alleviate
some of these concerns. The IzzyOnDroid repository pulls builds
directly from GitHub and is the next best thing to the developers' own
repositories.
However, it is not something that we can recommend, as
apps are typically removed from that respository when they make it to
the main F-droid repository. While that makes sense (since the goal of
that particular repository is to host apps before they're accepted
into the main F-Droid repository), it can leave you with installed
apps which no longer receive updates.
That said, the F-droid and IzzyOnDroid repositories are home to
countless apps, so they can be a useful tool to search for and
discover open-source apps that you can then download through Play
Store, Aurora Store, or by getting the APK directly from the
developer.
It is important to keep in mind that some apps in these
repositories have not been updated in years and may rely on
unsupported libraries, among other things, posing a potential security
risk. You should use your best judgement when looking for new apps via
this method.
Note
In some rare cases, the developer of an app will only distribute it
through F-droid (Gadgetbridge is one example of this). If you really
need an app like that, we recommend using Neo Store instead of the
official F-droid app to obtain it.
