People are turning to the 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 the recordings of high quality.

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.

The app also has the wave/PCM encoding with an adjustable sample rate (8-44 kHz). The interface is super simple. All you need to do is simply open the app and you see the record button.

Just one more aspect that we need to mention. Note, that the app does not always record the 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.

2. Smart Recorder and transcriber

There are numerous life situations when we need to secretly record a conversation. The main problem is, that because we have to hide a phone during a recording it may be hard to recognize the conversation on it later and make transcriptions.

You can always push the app to the playback and it will start making recording latently so the person you are talking to won’t notice anything. After you made a recording, you can proceed to it and mark the part that you would like to transcribe into the written form. Then the app will transcribe it into the text. It works with the English language only.

In fact, the app includes far more options than those, it is highly customizable in terms of record settings and even allows you to tag your recording by geolocation. With call recording – the situation is the same, it is not clear if it’s going to work.

5. Automatic Call Recorder

Now let’s talk about recording the calls. It may be an important part of hidden recordings as well. With this app, you can switch its function so it records all your calls automatically. You can easily record phone calls from both sides with a clear voice.

Both incoming and outcoming calls can be recorded in high quality. The problem is that many voice recording apps don’t include that function as it is considering spying. Well, if you install this app as an addition you will be fully equipped.

The app supports AMR, 3GP, MPEG4 format to record. You can record your phone calls both manually and set an automatic mode. Another additional feature here that may be useful is that Automatic Call Recorder can identify the unknown and hidden numbers.

What is more, nowadays we have such a big problem with spammers, telemarketers and phone fraudulence which get to know our number from nowhere and then they call us all the time. So, in this case, the app identifies such numbers as well and it gives you an immediate warning.

Important information for  Xiaomi and Huawei devices owners: you need to add the app into the White List on your device, otherwise it will be blocked by the system and your calls are not going to work.

6. Automatic call recorder

Now let’s see what iOS has to offer us in terms of recording the phone calls. Speaking roughly, it is an analog of the previous app, but for iOS. Well, maybe the interface is different. It can record your phone calls in the 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?

Editing of recorded audios is also possible. You can cut a file or accelerate its speed. Then, if you want, you can quickly upload recordings to Slack, Google Drive, Dropbox, Onedrive.

7. Voice Recorder & Audio Editor

This app is probably is a cherry on our list. It combines almost all the functions of the apps we mentioned before. So if you planning a really serious business with your hidden records this might be your universal tool. This Voice Recorder allows you to record unlimited time of conversations, voice and all the stuff you want.

In order to start recording quickly, you can simply place the recording button form the app to your home screen. What is more, this app includes an option of transcribing records into the text as well.

Also, if you upgrade your profile, you can add notes to the various recordings you made previously. The app allows to record voice in different formats, there are also some possibilities for editing, for example, you can trip or slow down the record.

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 that 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

Originally this app was not made for the secret recordings but you can turn it into software like this since there are all the ways to do that.
