Fitness app ideas – the development perspective

Fitness App Development Technologies

Certain hardware requirements and tool integrations need to be met to satisfy the most desired features of fitness apps and activity tracking devices. In this section of the blog, we would discuss the development perspective of fitness apps that have been split into three subsections below.

Hardware requirements

Smart fitness wearables are providing extraordinary features and facilities that require a wide variety of sensors to transmit data to their mobile apps. Here is a descriptive list of key sensors needed by fitness tracking devices.

Global Positioning System or GPS

GPS or Global Positioning System, a space radio-navigation system is a collection of 31 GPS satellites orbiting Earth currently. The constellation of GPS satellites is responsible for broadcasting navigation signals to provide us with accurate position and time information anywhere on Earth.

Fitness apps and fitness trackers employ GPS sensors to benefit users with their position & location information, allowing them to track their motion, and monitor their speed. This is ideal for users who hike, run, walk, and ride cycles to stay fit.

ECG Sensors

ECG Sensors

Inactive life poses the biggest threat to our cardiac muscle’s healthy functioning. According to WHO, about 17.9 million people die every year from cardiovascular diseases. Cardiac problems continue to remain the most prominent cause of death in the United States to date.

Therefore, ECG sensors, in the form of optical sensors, help to measure heart rate, blood saturation changes and thereby determine the cardiac cycles. The ECP app of the Apple Smartwatch Series 4 can even generate an electrocardiogram report for users.


Barometric Altimeters

A barometric altimeter helps to measure altitude. Thus, an altimeter can measure elevation and atmospheric pressure. So, it aids in measuring the number of stairs or an elevated level climbed up by the user and consequently calculating the number of calories burnt in the process.

Gyroscopes & Accelerometers

Gyroscopes & Accelerometers

A gyroscope measures the orientation and angular velocity of an object. Smart wearables and fitness apps employ a gyroscope, accelerometer, and a compass to measure the distance traveled by the users.

Along with this, the activity tracker also records the speed of travel to ultimately calculate the number of calories burnt by the wearer. These are essential because the detection of motion is one of the most primary functions offered by fitness apps.

Accelerometers that are mostly used to measure the acceleration of motion also help to monitor the sleep pattern and sleep duration of the user.

Tools to support a broad range of features

Now that you have vividly understood the hardware requirements of the fitness trackers, you will now look at the requisite tools to provide various app functionalities.
