MIKU

Review by eFreeware

MIKU is a Parenting app from MIKU, INC. that pairs with a Miku device to monitor video, audio and breathing. It is free to download, carries no ads, and offers in-app purchases. For parents who already own the matching hardware, it is the intended way to see what that device is picking up.

The appeal is straightforward: one app that covers three monitoring streams rather than separate tools for each. Anyone weighing a Miku device should treat the app as part of the package, since the monitoring itself comes from the device rather than the phone.

What the app actually does

The app's job is to display what a Miku device captures. Video, audio and breathing are the three streams it handles, which covers the usual concerns of a nursery monitor: seeing the crib, hearing the room, and tracking breathing.

That is the whole scope. The app is not a game or a general parenting tool. It exists to connect you to a piece of hardware.

Because the monitoring depends on the device, the app is best understood as a viewer rather than a standalone product. Without the hardware, there is nothing for it to show.

The hardware requirement shapes everything

MIKU needs a Miku device to do its job, which makes it a companion rather than a replacement for a monitor.

This is not a flaw so much as the nature of the product. If you already own a Miku device, the app is the natural companion. If you do not, the app on its own will not give you video, audio or breathing monitoring.

The free download and absence of ads are worth noting, though the app does offer in-app purchases. I would treat the in-app purchases as something to check before committing.

A long-running app with a mixed reception

MIKU has been on the Play Store since June 1, 2018, and was most recently updated on July 27, 2026. That is a long lifespan for a companion app.

It has over 50,000 installs and a 1.5 average from 1,392 ratings, with 943 written reviews. That average is low, and anyone considering the app should weigh it alongside their own needs and the hardware they already own.

Ratings do not tell you whether the app will work for your setup, but they are a signal worth acknowledging. The combination of a long lifespan and a low average suggests the experience has not satisfied everyone.

Who MIKU is built for

MIKU is for parents and caregivers who own a Miku device and want to view its video, audio and breathing monitoring in one place. That is the audience the app is designed around.

If you are shopping for a baby monitor and do not yet own the hardware, the app is not the starting point; the device is. The app comes into its own once the device is in the nursery.

For existing owners, the free download and the absence of ads make it easy to try. The in-app purchases and the low rating are the two things I would look into before relying on it.

A companion app for Miku device owners

MIKU does one thing: it shows what a Miku device sees, hears and tracks.

The 1.5 average from over a thousand ratings is a caution, and the in-app purchases are worth understanding before you rely on it.

My recommendation is for existing Miku device owners who want the official companion app and are willing to weigh the rating against their own experience. If you do not own the device, the app has nothing to show you.
