Useful smartphone apps. For leisure and not only

There are a huge number of different smartphone applications in the Google Play and App Store. However, finding useful and relevant things among them can be quite difficult. We have selected unusual programs that will come in handy in everyday use.

Using augmented reality technology, this “app” allows you to measure distances using a smartphone camera. It can be useful if you are planning a rearrangement in a room or, for example, buying a new wardrobe and want to make sure that it fits into the living room space.

There is no need to remove things from the room – the application automatically detects where the floor intersects with a given point, even if it is behind furniture. All you need is good lighting and a textured floor (that is, with visible details, not uniform).

CamToPlan can build a floor plan and calculate the approximate area. Keep in mind — the measurement results will not be very accurate and are only suitable for visual guidance. If you are planning construction or finishing work, it is best to use a regular tape measure or laser rangefinder.

WiFi Analyzer
Application for analyzing WiFi networks. It clearly shows the signal strength and distance to the router, as well as secondary data: connection frequency (2.4 or 5 GHz), encryption type, number of channels and MAC address. It is useful if you are looking for a high-speed access point in an entertainment complex or a large office center. It will also be useful if you need to find out detailed data about a specific network, but this can be done only after connecting to it.

A startup of Russian developers who have noticed that recently people are increasingly looking for background music for work or sleep. The application analyzes the owner’s data (for example, heart rate and cadence), adds information about external factors (time, weather, location) and based on this generates a unique sound background. The algorithm was written on the basis of the book “Physics and Anatomy of Music” by Alexey Nasretdinov

“I’m tired of writing about what others are doing, and I wanted to do something myself,” says Oleg. “Therefore, I left journalism and created an agency that was engaged in the development of mobile applications.”

“… on streaming services, the demand for playlists for sleep, relaxation or concentration has increased. People actively consume this content, and it’s understandable why: they are trying to help themselves solve the problem of lack of sleep and fatigue. That is, many listen to music not in order to enjoy some of its artistic qualities, they turn on the playlist not because they like the tracks from there, but simply use sounds as medicine ”.

The name of the application speaks for itself – it is an analogue of a device for measuring sound. Using the built-in microphone, it measures the amount of noise and outputs the result in decibels (dB).

To understand what is hidden behind dry numbers, we give an approximate noise scale:
