March arrives, the month of change to the spring season and the eve of Holy Week. Coinciding that it is Monday, it is time to look for the paid applications that Google Play makes free for a few days, like we always do.
So, it is the opportunity to start the month on the right foot to equip our Android with a series of applications that can be very useful, and that we are going to reel them in the following lines.
ProCam
We start with what is a very complete camera app, with advanced settings to take the best possible picture, since some native cameras do not usually offer as much parameterization as this. White balance, ISO, Focus / Defocus mode, recording time lapse, etc.
Learn Business English Premium
Knowing English to chat with people on the street is very good, but ... what if we want to talk business or know how to sell our company well? For this, the vocabulary of the language changes a lot, so it is necessary to have this millennials app to know how to formulate a proposal or speak at a conference in that language.
TechproSS Plus
This app allows control the entire security system including cameras, Wi-Fi or alarms. Of course, it is only useful if we are clients of the company of that name.
iPray BCP
It is a project originally thought for the iPhone but brought to Android shortly after, with the idea of taking the Book of Common Prayer in a single app, as if it were a digital Bible. In this case, it shows lessons and events following the church calendar.
3D Penguins Pro Live Wallpaper
If you are a fan of this seabird, you can always have them present on your mobile screen, set in an icy environment similar to that of the Poles.
Determinant of the matriz Pro
It is perfect to save us the work of calculating the determinant, especially when dealing with somewhat large matrices, although it only shows the solutions directly.
90X Duplicate File Remover Pro
Use the Artificial Intelligence to automatically eliminate all those duplicate files that reside on our device.
Erosion - Icon Pack
It offers a particular design of the icons, with compatibility for many applications and a chat with developers for suggestions or notifications of problems.

Silence Camera - SLCamera
It is a simple tool to block the display of notifications on screen while we use the camera, so that it does not bother us if we are taking a photograph or a video.
Christmas 3D Live Wallpaper
It is not that it is the most suitable date to offer this app, but we can take advantage of the occasion and have it installed for the following Christmas as a wallpaper.
Shot on Watermark on Photo
A few years ago, having a photograph with a watermark was almost like jumping out of a window, it became very annoying. Now the opposite happens, it has become fashionable to wear watermark on images as one more effect, and that is the function that this app fulfills.
