People are turning to voice recorders all the time – and the popularity of this app confirms it one more time. This is a basic voice recording app that is easy to use and which makes recordings of high quality.

One of them is that the app can automatically skip the silent parts during the recording, thus saving the memory space on your phone and also not making the conversation as long as it is in real life. It allows you, for example, to catch night sleep talks or maybe some snoring, whatever comes first.

There is actually a funny story behind how this app was invented. The wife wanted to prove to the developer that he talks during his sleep. Well, the app then proved that he does. In the sense of making the hidden recordings, it is also perfect – you just need to start a record and then just roll down the app so nothing is visible on your screen. You can even block your phone and leave it in your pocket.

Just one more aspect that we need to mention. Note, that the app does not always record phone calls. Some manufacturers simply block this function in the gadget itself (for privacy rights reasons). So in case, you need specifically to record a phone call – go for another app.

It can record your phone calls in automatic mode as well. Well, maybe here you will find a little bit more possibilities to manipulate the records.

Here you can organize your recorded calls into categories. For example, if you work as a receptionist at a hotel and receive lots of calls every minute it may be hard to write everything down. So why not just record a call, create a separate category for it and then listen to it later?

And finally, we got an app that can record phone calls and make regular records at the same time! The third “caller” is our recording line which will save your phone call. By the way, it is not possible to record phone calls using the built-in microphone on your iPhone.

The interface of the app is also worth mentioning. It differs significantly from the rest of the apps in the best way. If all the voice recorders are simple apps that tend to have a black or white background and nothing else, this one is decorated with small pictures and it is stylized to the old-fashioned recorder which looks really good for ann like this.




8. Easy Voice Recorder

10. Secret Voice Recorder

If you try to search for hidden voice recorder apps in Google Play you’ll discover that it’s really tricky when it comes to this topic.

Indeed, it’s a really simple software where you can just put the recorder running in the background and then just save a recording.
Another additional feature of this app is that you can choose the formats of recording. What is more, there’s an analyzer of the sound, however, we didn’t really understand its purpose and its functionality since it just colors the diagram into another shade.
What really deserves your attention is the possibility to edit the recordings. You can also view and delete your previous files. After you have made a recording you can choose a format in which you want to save it.
However, remember all the personal data protection policies. All in all, this is not the best app that you can use, but this is one of the few ones that are strictly related to the topic.

And for those who don’t have the burden of timing, there is an option to just start recording by pressing the red button start.

Additionally, the app has the feature of the automatic detection of the Voice and it will start running automatically each time it detects The Voice nearby. In all other aspects, the app is extremely simple if not to say boring. The interface design is really dull and it’s obvious that the app doesn’t have lots of features.
