This app protects you from nosy friends

Both Google’s Play Store and Apple’s App Store contain countless apps, some of which are free and others for a fee. That’s not too much of a secret. However, what many people don’t know or don’t pay attention to is that paid full versions can often be downloaded without paying as part of an offer. We have picked out some particularly interesting free apps for you.

These pro apps are currently free (Android)

• AppLock PRO (4.79 euros) – With this app you can put a stop to any application on your smartphone. You want to show your friend a few pictures, but you don’t want him to open WhatsApp without being asked and look at your chats? Absolutely no problem with this app. (3.9 stars, 5,480 reviews)
• Date Calculator Pro (1.09 euros) – With this handy application you can calculate the time between two dates in just a few clicks. In addition, the tool offers many additional functions. For example, if you wish, you can only display the working days between two dates. (4.7 stars, 1,250 reviews)
• Heartless Knight (059 euros) – This app is a jump ‘n’ run game like it is written in the book. Even the look is based on classic pixel art. Just the thing for nostalgics and old-school gamers. (Over 1,000 downloads, no reviews)
• Demon Hunter: Premium (1.19 euros) – This game is really convincing. With almost 40,000 reviews, the average rating is an impressive 4.7 out of 5 stars. Only a few apps can keep up with that. But be careful: the game offers in-app purchases. (4.7 stars, 39,100 reviews)

• Aqueduct 101 (2.29 euros) – This puzzle game focuses on the so-called aqueducts or water pipes. These have become confused and no longer allow the flow of water to pass through. Now it’s up to the player to change this. (4.8 stars, 200 reviews)

FREE APPS WITH TRAPS – THIS IS WHAT YOU NEED TO BE AWARE OF

All applications listed above were available free of charge at the time of writing. Unfortunately, developers rarely indicate how long the offer lasts. If you like an app, you should download it as soon as possible.

Before downloading the free apps, however, we recommend taking a closer look at the respective pages in the Play Store or the App Store. Because some programs have various stumbling blocks.

In-app purchases and advertising

As a rule, in-app purchases and advertising are more common in free applications, but full versions are often not spared – regardless of whether they were downloaded for free or for a fee. This is especially relevant if the program you downloaded is a game intended for children. In such and similar cases, one of the following parental controls can help:

App permissions

Some applications rent by collecting user information and reselling it. If you want to be on the safe side, you should make sure that you only grant apps the permissions they need to work. An alarm clock typically doesn’t require access to the camera or your contacts, while a flashlight doesn’t need to care about your location data.
