About this app

Baby Monitor (Baby Alarm/Radio Nanny) - a godsend for parents! Courtship of the child - is a hard and troublesome work, which occupies all the free time! And when the child falls asleep finally appears free time to relax and give yourself time! Baby Monitor will help you in this! Baby Monitor will call you if your child wakes up or specified noise level will be exceeded. It works without Internet. The second phone can be a simple phone, not a smartphone (it's may be a second parents phone). You can also use this app as a (noise) SPL meter

Briefly the main features:
- work on the 2 (dual) SIM phones
- you can select SIM-card slot for making calls
- function "Call Me Back"
- pause at start and after alarm/call
- Two-way (loud) talkback
- turning on the speakerphone delay
- microphone sensitivity adjustment
- auto silent mode

- No advertising
- Pause after alarm
- Fine-tuning alarm noise level
- Low battery consumption
- Delayed start
- Does not require Internet
- It does not require a second phone to be a smartphone

Tips before you start to use:
- The phone receiving a call from the Baby Monitor can be any phone
- Ensure that the device has enough power (or better yet leave on charge)
- A call is made immediately, without select the SIM dialogue or the method call
- Set the phone at a distance of less than 2m from the child
- It is desirable to test the application multiple times

To start the Mary Baby Monitor/Radio Nanny configure it. To do this, click the Settings button.

Select a phone number from the phone book or enter it with the keyboard. This is the number to which calls will be received from the radio nanny when the surrounding noise exceeds the preset level.

Adjust the noise level to the desired parameter. To be able to quietly leave the baby alarm area after its launch switch on the Pause at startup. Note that this pause will also be applied after each alarm or incoming/outgoing call.

During an active call the speakerphone can be turned on. Just enable this option in the settings. So you can listen to surrounding sounds in the room where the baby sleeps and the ability speak soothing words to a child through the phone.

Do you want to know what is currently happening in the room where the child? Just call on the phone with the Baby monitor app from the number, which is specified in the settings. Radio Nanny will call you back immediately, within a few seconds!

Would you like automatically switch to silent mode when the application starts? Simply activate this option in the settings. Thus, incoming calls to your phone, where works Mary Baby Monitor, will have not vibrate or loud playing of a ringtone. Only silence.

Mary Baby Monitor can call you with any SIM-card (does not work on all devices!). We are constantly adding support for new Dual SIM phones.

We are always open to dialogue! Leave your comments and we will be happy to answer them!

Health to you and your baby!

Excellent app, simple and powerful. However on the screenshots on Google play there is an option 'speakerphone' which in my version can't be seen. Anything I'm missing here?!

This is just what you look for, and I don't even use the pro version. Simple and effective. The ads are not that anoying, just some random banners at the bottom of the screen. My advice: make a test call every time you use it and pay attention while setting it up, because if you set the noise level too low you will be prompted every time someone outside your baby's room slams the door. It really does the job. Thank you for this app!
