● A hybrid app is a software application that is built using a
combination of web technologies and native code.
● These apps can be run on multiple platforms, and are typically
easier and less expensive to develop than native apps.
● They are downloaded and installed from an app store, and
they also can be accessed through a web browser.
11

12. Pros of Hybrid Apps
● Cross-platform compatibility: Hybrid apps can run on multiple
platforms, such as iOS and Android, using a single codebase. This
reduces development time and costs, as well as maintenance.
● Access to device features: Hybrid apps have access to some
device features, such as the camera, GPS, and accelerometer,
through the use of APIs and plugins.
● Cost-effective: Hybrid apps are typically less expensive to
develop and maintain than native apps because they use a single
codebase.
● Reusability of code: The code can be reused for different
platforms, reducing the development time.
12

13. Cons of Hybrid Apps
● Performance: Hybrid apps may not perform as well as native apps, as
they have to rely on web technologies to access the device's features,
which can slow down the app and create a less responsive user
experience.
● Limited access to device features: Hybrid apps may not have access to
all the device's features and capabilities, as they are reliant on the
availability of APIs and plugins.
● Device fragmentation: There is a large number of devices and
versions of the operating system, making it hard to ensure
compatibility and test on all devices.
● Dependence on 3rd party tools: The app's performance, security and
user experience can be affected if the 3rd party tools used are not
well-maintained or updated 13

14. Web apps
● A web app is a mobile-optimized website that can be
accessed through a web browser.
● They do not require installation and can be run on any device
with a web browser.
● These apps can be accessed via a URL and they don't need to
be downloaded and installed on the device.
14

15. Pros of Web Apps
● Cross-platform compatibility: Web apps can run on any
device with a web browser, regardless of the operating
system or device type.
● No installation required: Web apps do not require installation
and can be accessed immediately through a web browser.
