Google Fit

Google Fit is a health-tracking platform developed by Google for the Android operating system and Wear OS. It is a single set of APIs that blends data from multiple apps and devices.[1] Google Fit uses sensors in a user's activity tracker or mobile device to record physical fitness activities (such as walking or cycling), which are measured against the user's fitness goals to provide a comprehensive view of their fitness.

Google Fit was announced at the Google I/O conference on June 25, 2014. A software development kit for Google Fit was released on August 7, 2014.[1] Fit launched to the public on October 28, 2014.

In August 2018, Google announced a revamp to its Android Fit platform which adds activity goals based on activity recommendations from the American Heart Association and the World Health Organization.[2] The updates are meant to help Fit better provide metrics for activities other than walking, and encourage users to engage in activities that will raise the heart rate without necessarily requiring a trip to the gym.[3]


Google Fit provides a single set of APIs for apps and device manufacturers to store and access activity data from fitness apps and sensors on Android and other devices (like wearables, heart rate monitors or connected scales). Users can choose who their fitness data is shared with as well as delete this information at any time.[1]

Activity tracker

An activity tracker, also known as a fitness tracker, is a device or application for monitoring and tracking fitness-related metrics such as distance walked or run, calorie consumption, and in some cases heartbeat and quality of sleep. It is a type of wearable computer. The term is now primarily used for smartwatches that are synced, in many cases wirelessly, to a computer or smartphone for long-term data tracking. There are also independent mobile and Facebook apps. Some evidence has found that the use of these type of devices results in less weight loss rather than more.

Android Lollipop

Android "Lollipop" is a codename for the Android mobile operating system developed by Google, spanning versions between 5.0 and 5.1.1. Unveiled on June 25, 2014 at the Google I/O 2014 conference, it became available through official over-the-air (OTA) updates on November 12, 2014, for select devices that run distributions of Android serviced by Google (such as Nexus and Google Play edition devices). Its source code was made available on November 3, 2014. It is the fifth major update and the twelfth version of Android.

One of the most prominent changes in the Lollipop release is a redesigned user interface built around a design language known as Material Design, which was made to retain a paper-like feel to the interface. Other changes include improvements to the notifications, which can be accessed from the lockscreen and displayed within applications as top-of-the-screen banners. Google also made internal changes to the platform, with the Android Runtime (ART) officially replacing Dalvik for improved application performance, and with changes intended to improve and optimize battery usage.

As of October 2018, statistics issued by Google indicate that the Lollipop versions have 17.9% share combined of all Android devices accessing Google Play.Lollipop is succeeded by Marshmallow, which was released in October 2015.

Google Calendar

Google Calendar is a time-management and scheduling calendar service developed by Google. It became available in beta release April 13, 2006, and in general release in July 2009, on the web and as mobile apps for the Android and iOS platforms.

Google Calendar allows users to create and edit events. Reminders can be enabled for events, with options available for type and time. Event locations can also be added, and other users can be invited to events. Users can enable or disable the visibility of special calendars, including Birthdays, where the app retrieves dates of births from Google contacts and displays birthday cards on a yearly basis, and Holidays, a country-specific calendar that displays dates of special occasions. Over time, Google has added functionality that makes use of machine learning, including "Events from Gmail", where event information from a user's Gmail messages are automatically added to Google Calendar; "Reminders", where users add to-do activities that can be automatically updated with new information; "Smart Suggestions", where the app recommends titles, contacts, and locations when creating events; and "Goals", where users enter information on a specified personal goal, and the app automatically schedules the activity at optimal times.

Google Calendar's mobile apps have received polarized reviews. 2015 reviews of the Android and iOS apps both praised and criticized the design. While some critics praised the design for being "cleaner", "bold" and making use of "colorful graphics", other reviewers asserted that the graphics took up too much space. The Smart Suggestions feature was also liked and disliked, with varying levels of success in the app actually managing to suggest relevant information upon event creation. The integration between Google Calendar and Gmail was praised, however, with critics writing that "all of the relevant details are there".
